15 Best Apps to Learn Japanese for Beginners and Beyond

Japanese is one of the most popular languages to learn worldwide. Whether you're drawn by anime and manga, planning to visit Tokyo, or pursuing business opportunities in Japan, the motivation is there. But here's the problem: Japanese is brutally difficult. You're dealing with three writing systems (hiragana, katakana, and kanji), complex grammar structures, and keigo -the elaborate system of politeness levels that changes entire sentence structures depending on social context. Most language apps treat Japanese like it's Spanish with different characters. They'll drill you on hiragana flashcards and basic vocab matching, then leave you stranded when you try to have an actual conversation.

We spent weeks reviewing 15 Japanese learning apps to find which ones actually build conversational ability, not just recognition skills. Some are excellent for specific aspects like kanji memorization or grammar drilling. Others promise fluency but deliver nothing more than gamified vocab lists. A few stand out for helping you speak Japanese with confidence.

Full disclosure: we built Victor AI, which is on this list. Victor AI is an AI language-learning app that helps you practice speaking Japanese with real-time pronunciation and grammar corrections, 3,000+ structured lessons, and a 60-Day Speaking Challenge. We're biased, obviously, but we've been honest about where other apps excel and where they fall short.

Quick Summary: What We Found

After testing 15 apps, here's what matters for learning Japanese:

• Speaking practice is severely lacking across most apps. The U.S. Foreign Service Institute classifies Japanese as Category IV (hardest for English speakers), requiring approximately 2,200 hours to reach professional proficiency. Yet most apps focus on passive recognition rather than active production.
• Kanji learning requires a dedicated system. Apps that treat kanji like any other vocabulary inevitably fail. You need spaced repetition specifically designed for the 2,136 jōyō kanji.
• Grammar explanations matter more in Japanese than romance languages. Particle usage, verb conjugations, and politeness levels cannot be absorbed through immersion alone -at least not efficiently.
• Pitch accent is almost universally ignored. Japanese is a pitch-accent language, but most apps don't even mention this, leading to comprehensible but foreign-sounding pronunciation.
• AI conversation partners have changed the game. Apps with structured speaking output and instant corrections -like Victor AI's AI conversation practice -are critical for Japanese because pronunciation mistakes compound with politeness-level errors. Getting real-time feedback prevents fossilization of bad habits.
• No single app does everything. The best learners stack tools: one for kanji, one for grammar, one for speaking practice. The key is finding your weak points and addressing them systematically.

1. Victor AI -AI Conversation Partner with Real-Time Corrections

Victor AI is our top pick because it solves Japanese's biggest learning problem: you can't improve at speaking without actually speaking. The app functions as an AI conversation partner that listens to your Japanese, corrects pronunciation and grammar in real time, and adapts difficulty based on your level.

The core structure is seven learning modes ranging from beginner drills to advanced situational conversations, supported by over 3,000 structured lessons. The 60-Day Speaking Challenge guides you through two missions daily, taking 10-15 minutes total. Every response you give gets analyzed for pronunciation accuracy, grammar correctness, and naturalness. When you make mistakes with particles (は vs が, に vs で), verb conjugations, or politeness levels, the AI explains why and shows you the correct form immediately.

What sets Victor AI apart for Japanese specifically is the focus on output from day one. Most apps let you passively consume content for months before asking you to produce anything. Victor AI forces production immediately, which accelerates learning but feels uncomfortable initially. The AI is patient though -it never moves forward until you get it right. For Japanese learners, this addresses the politeness-level problem directly: you practice formal speech, casual speech, and humble/honorific forms in context rather than memorizing abstract rules.

What's missing: Victor AI doesn't explicitly teach kanji recognition or writing. You'll learn to read and pronounce kanji that appear in lessons, but if your goal is passing the JLPT N2 kanji section, you'll need a supplementary tool. The app also doesn't focus on pitch accent training, though pronunciation feedback does catch major pitch errors.

Best for: Anyone serious about speaking Japanese conversationally, from beginners to intermediate learners who want structured daily practice.

Price: Free to start with limited lessons; $3.99/month for premium unlimited access.

2. Duolingo -Gamified Japanese with Major Gaps

Duolingo's Japanese course is where many beginners start, and it's not a terrible entry point. The app teaches hiragana and katakana efficiently through repetition-based matching exercises, and the gamification (streaks, XP, leagues) creates genuine motivation for daily practice. Early lessons cover basic sentence structures and core vocabulary in a low-pressure environment.

The problems emerge quickly. Duolingo's kanji progression is chaotic -it introduces kanji seemingly at random without teaching radicals, meanings, or systematic memorization strategies. You'll see 食べる (to eat) in one lesson and then not encounter 食 again for weeks, by which time you've forgotten it. The app offers almost no speaking practice despite having a microphone feature; the speech recognition is so forgiving that you can mumble random sounds and pass. Grammar explanations are buried in tiny "tips" sections that most users skip, leading to pattern-matching without understanding. You'll be able to translate "The cat drinks milk" without knowing what を or は actually do.

Duolingo's pedagogy treats Japanese like a word-substitution puzzle built on English grammar, which works for Spanish but fails catastrophically for a language with fundamentally different syntax. By the time you finish the course, you'll recognize a few hundred words and maybe construct simple present-tense sentences, but you won't be conversational.

Best for: Absolute beginners wanting a gamified introduction to hiragana, katakana, and basic vocabulary before committing to serious study.

Price: Free with ads; $7.99/month for Super (ad-free, unlimited hearts).

3. WaniKani -The Kanji Learning Powerhouse

WaniKani does one thing and does it brilliantly: teaching you to read and understand kanji through spaced repetition and mnemonic stories. The system teaches kanji by breaking them into radicals (the component parts), then building vocabulary using those kanji. Each level introduces 20-30 new kanji along with associated vocabulary, and you can't proceed until you've proven mastery through spaced repetition reviews.

The mnemonics are genuinely memorable -often absurd, occasionally crude, always effective. You'll remember that 休 (rest) is a person leaning against a tree, or that 働 (to work) combines person + movement because working means a person in motion. Over 60 levels, WaniKani systematically teaches all 2,136 jōyō kanji plus about 6,000 vocabulary words. Users who complete the full course report being able to read Japanese novels, news articles, and manga without constant dictionary lookups.

The limitation is severe: WaniKani teaches zero grammar, zero speaking, zero listening comprehension. It's purely a reading and recognition tool. You'll know what 勉強 means (study) but have no idea how to use it in a sentence or conjugate 勉強する. The pacing is also rigid -you're locked into the level progression even if you already know some kanji, and reaching level 60 takes most users 1.5 to 2 years of daily practice.

Best for: Learners who specifically need to master kanji for reading Japanese content, especially manga, light novels, or business documents. Must be paired with grammar and speaking tools.

Price: First three levels free; $9/month, $89/year, or $299 lifetime subscription.

4. Bunpro -Grammar SRS System

Bunpro applies the spaced repetition system (SRS) concept to grammar instead of vocabulary. The platform organizes Japanese grammar points by JLPT level (N5 through N1) and uses fill-in-the-blank sentences to drill each grammar pattern until it's automatic. When you encounter a new grammar point -say, ~てもいい (it's okay to...) -Bunpro shows example sentences, explains the usage, and then quizzes you repeatedly over days and weeks.

The explanations are detailed and often reference multiple Japanese grammar textbooks (Genki, Tobira, A Dictionary of Japanese Grammar). You can read multiple perspectives on tricky points like the difference between ~ている and ~てある. The SRS scheduling is smart: grammar points you struggle with appear more frequently until you consistently get them right.

What Bunpro doesn't do is give you speaking practice or realistic conversation. Everything is text-based, multiple-choice, or fill-in-the-blank. You're learning to recognize grammar patterns and translate them, not to use them fluently in speech. The example sentences can feel artificial -grammatically correct but not how people actually talk. Some users also find the fill-in-the-blank format frustrating because multiple grammar patterns might technically work, but Bunpro only accepts one specific answer.

Best for: Intermediate learners who want systematic, structured grammar study and are preparing for JLPT exams. Works best alongside speaking practice from another source.

Price: Free trial with limited grammar points; $5/month for full access.

5. LingoDeer -Purpose-Built for Asian Languages

LingoDeer was designed specifically for Asian languages (Japanese, Korean, Chinese) rather than being a European-language app retrofitted with Japanese. This foundational difference shows immediately. The Japanese course properly teaches the three writing systems in sequence, explains particles with actual detail, and introduces grammar concepts in a logical progression that respects Japanese's structure.

Lessons combine reading, listening, and some speaking exercises with better-than-average speech recognition. Grammar explanations appear throughout rather than being hidden, and the app explicitly teaches conjugation patterns for verb groups. Vocabulary is contextualized in full sentences rather than isolated words. The interface is clean and uncluttered compared to Duolingo's carnival of notifications.

Where LingoDeer falls short is depth and variety at higher levels. The beginner and elementary content is excellent, but once you hit intermediate territory, lessons become repetitive and the conversation practice remains limited. You're still mostly translating sentences rather than having freeform conversations. The app also doesn't integrate a dedicated kanji learning system -you'll encounter kanji in lessons, but without the systematic SRS approach that WaniKani offers.

Best for: Beginners who want clear, comprehensive grammar explanations and a structured curriculum designed specifically for Japanese's linguistic features.

Price: Free trial with limited access; $11.99/month or $79.99/year.

6. Pimsleur -Audio-Based Japanese Through Repetition

Pimsleur's method is simple: 30-minute audio lessons where a narrator guides you through conversations, asking you to respond in Japanese with progressively longer and more complex phrases. The technique, called graduated interval recall, has you repeat phrases at specific intervals to cement them in memory. Everything is audio -no reading, no writing, just listening and speaking.

For pronunciation, Pimsleur is excellent. You develop a good accent and natural rhythm because you're mimicking native speakers and receiving correction in real time (the narrator tells you the correct pronunciation if you get it wrong). The method builds conversational ability faster than text-based apps because you're practicing actual spoken dialogue from lesson one.

The problems: Pimsleur is expensive relative to other apps, the pace is agonizingly slow for motivated learners (30 minutes daily for one level takes about a month), and you won't learn to read or write Japanese at all. After 30 hours of Pimsleur Japanese, you'll have decent pronunciation and maybe 500 spoken phrases memorized, but you won't be able to read a restaurant menu. The rigid structure also doesn't adapt to your interests -you're learning the phrases Pimsleur chose, which may not align with your goals.

Best for: Audio learners, commuters, and beginners who want to develop good pronunciation without the cognitive load of learning three writing systems simultaneously.

Price: $14.95/month for one language, or $20.95/month for all languages; also available as one-time purchase of individual levels.

7. Rosetta Stone -Immersion Method Struggles with Japanese

Rosetta Stone's core philosophy is immersion: no translations, no explicit grammar explanations, just pictures paired with Japanese sentences. You're supposed to intuit meaning through context, the way children learn their first language. The method has worked reasonably well for romance languages.

For Japanese, it's a disaster. Japanese grammar is too different from English to be absorbed efficiently through pure immersion without guidance. The app will show you pictures and sentences using particles like を, が, に, で without ever explaining what they do. You might eventually intuit some patterns, but it's painfully inefficient compared to just reading a one-paragraph explanation of object-marking particles. The politeness system is barely addressed -you'll learn phrases without understanding whether you're speaking formally or casually, which can be socially disastrous in Japan.

Rosetta Stone also feels outdated in 2026. The images look like stock photos from 2003, the voice recognition is mediocre, and the price is absurdly high for what you get. Many of the lessons feel irrelevant -you're learning vocabulary about farming equipment before you can introduce yourself properly.

Best for: Learners who strongly prefer a no-translation, immersion-only approach and have high tolerance for slow, inefficient progress. Honestly, there are better options for almost everyone.

Price: $11.99/month, $143.88/year, or $299 lifetime for all languages.

8. italki -Live Japanese Tutors

italki isn't an app with lessons -it's a marketplace connecting you with Japanese tutors for one-on-one video lessons. You browse tutor profiles, read reviews, watch introduction videos, and book sessions (typically 30 or 60 minutes). Tutors range from professional teachers with credentials to community tutors who are native speakers without formal teaching training.

The advantage is obvious: real human conversation with a native speaker who corrects your mistakes and adapts to your level. You get immediate feedback on pronunciation, grammar, and natural phrasing. You can focus on your specific goals -JLPT prep, business Japanese, anime slang, whatever you need. The best tutors are genuinely excellent teachers who structure lessons, assign homework, and track your progress.

The disadvantages: cost ($15-40/hour adds up fast), scheduling friction (coordinating time zones and booking in advance), and quality variance (some tutors are just native speakers with no teaching skills). You also need to be at least a strong beginner to benefit -absolute beginners burn through expensive lesson time learning things they could've gotten from an app. And lessons require preparation and homework to be effective; if you show up having done nothing, you're wasting time and money.

Best for: Intermediate to advanced learners who need real conversation practice, have the budget for it, and are self-directed enough to prepare for lessons and practice between sessions.

Price: $10-40/hour depending on tutor; some offer discounted trial lessons.

9. HelloTalk -Language Exchange with Native Speakers

HelloTalk is a language exchange app designed to connect you with native Japanese speakers who want to learn English (or your native language). You create a profile, match with partners based on interests and goals, and chat via text, voice messages, or voice/video calls. The app includes built-in translation, correction tools, and pronunciation features.

When it works, it's fantastic. You get free conversation practice with real people, make international friendships, and learn casual, natural Japanese that textbooks don't teach. You'll pick up current slang, internet language, and regional dialects. Text chat is lower pressure than live conversation, giving you time to look up words or construct sentences carefully.

When it doesn't work, it's frustrating. Many users are more interested in free English practice than seriously helping you learn Japanese -you end up teaching English more than learning Japanese. Finding a consistent, compatible language partner takes time and luck. Conversations often devolve into small talk rather than structured learning. And the app's social features (moments, feeds) can be distracting rather than educational.

Best for: Intermediate learners who want free text-based conversation practice and are comfortable with the unstructured, social nature of language exchange. Works best when you find 2-3 serious partners and maintain regular practice.

Price: Free; $6.99/month for VIP features (unlimited translations, more advanced filters).

10. JapanesePod101 -Massive Podcast Library

JapanesePod101 offers an enormous library of Japanese audio and video lessons organized by skill level (Absolute Beginner through Advanced). Each lesson is a podcast episode (5-25 minutes) featuring dialogue between hosts, followed by vocabulary explanations, grammar breakdowns, and cultural notes. The library has thousands of lessons covering everything from survival phrases to business etiquette to news discussions.

The audio quality is professional, the hosts are engaging, and the content variety is impressive. You can find lessons on your specific interests -anime Japanese, travel phrases, job interview language. Lesson notes provide transcripts, vocabulary lists, and grammar explanations. The sheer volume of content means you'll never run out of material.

The problem is that it's all passive. You're listening, reading lesson notes, maybe repeating phrases to yourself, but there's no interactive component forcing you to produce Japanese. It's easy to binge hours of JapanesePod101 and feel productive without actually improving. The platform also suffers from aggressive upselling -constant emails pushing you toward higher-priced tiers and add-on products.

Best for: Self-directed learners who like audio-based learning and need a massive content library for listening practice. Best used as a supplement to an interactive speaking/writing app.

Price: Free basic access with limited lessons; $8/month for basic subscription, $25/month for premium with all features.

11. Memrise -Native Speaker Video Clips

Memrise's Japanese course features thousands of video clips of native speakers saying words and phrases. Instead of computer-generated voices, you see real people speaking naturally. The app uses spaced repetition to drill vocabulary, and the video component helps with pronunciation, facial expressions, and natural speed.

Seeing multiple people say the same phrase demonstrates that there's variation in pronunciation and emphasis -Japanese doesn't sound exactly the same from every speaker. This is genuinely valuable and missing from most apps. Memrise also includes some grammar explanations and cultural notes, though these are secondary to vocabulary drilling.

What's missing: no structured grammar curriculum, no speaking output requirement, and no systematic kanji learning. You're building vocabulary in isolation rather than using it in conversation. The app's courses are community-created, which means quality varies dramatically. Some courses are excellent; others are riddled with errors or poor organization.

Best for: Learners who want to hear authentic Japanese pronunciation from multiple native speakers and prefer vocabulary drilling with real video context. Works best as a supplement.

Price: Free with limited features and ads; $8.49/month or $44.99/year for premium.

12. Drops -Visual Vocabulary in 5-Minute Sessions

Drops focuses exclusively on vocabulary through beautiful, minimalist visual design and rapid-fire 5-minute sessions. You see an image, hear the Japanese word, and swipe or tap to match or categorize it. No grammar, no sentences, no explanations -just vocab drilling in short bursts designed to fit into idle moments.

The visual design is legitimately gorgeous, and the 5-minute limit makes it easy to maintain a daily habit. You never feel overwhelmed. The app covers a decent range of vocabulary topics (food, travel, business, hobbies) with both essential and niche words.

But it's shallow. You're learning isolated vocabulary without context, grammar, or speaking practice. There's no kanji learning system -you'll see kanji in lessons, but without explanation or systematic study. You can't read a Japanese sentence with just isolated vocabulary, and you certainly can't have a conversation. Drops is a supplementary tool at best, and an expensive one at that given how limited the content is.

Best for: Beginners who want to build basic vocabulary in very short daily sessions, or as a 5-minute warmup before using a more comprehensive app.

Price: Free for 5 minutes per day; $9.99/month or $69.99/year for unlimited use.

13. Anki -The Power-User Flashcard Tool

Anki is open-source spaced repetition software that's become the standard among serious language learners. You create flashcards (or download shared decks), and Anki schedules reviews using an algorithm that shows you cards right before you're about to forget them. It's infinitely customizable -you can add audio, images, example sentences, stroke order diagrams, anything.

For Japanese, there are pre-made Anki decks for everything: Core 2k/6k/10k vocabulary, JLPT N5-N1, kanji with mnemonics, sentence mining from anime. You can also create your own decks by mining vocabulary from content you're consuming (books, shows, podcasts). The algorithm is more sophisticated than any app's built-in SRS, and power users swear by it.

The downsides: steep learning curve, zero structure (you have to find or create your own content), and it requires iron self-discipline. There's no gamification, no lessons, no guidance -just a pile of flashcards that you review daily. If you download a 10,000-card deck, you're committing to years of daily reviews. The iOS app also costs $25 upfront, though the desktop version is free.

Best for: Dedicated, self-directed learners who want maximum control over their study materials and are willing to invest time learning how to use the system effectively. Not for beginners.

Price: Free on desktop and Android; $24.99 for iOS app (one-time purchase).

14. Busuu -Community Learning with Grammar Focus

Busuu combines structured lessons with a community feature where native speakers correct your writing and speaking exercises. Lessons cover vocabulary, grammar, dialogues, and writing practice, organized into a clear progression from A1 to B2 (using CEFR levels adapted for Japanese).

The grammar explanations are decent, and the community correction feature provides human feedback on your output, which is valuable. You submit a writing or speaking exercise, and native Japanese speakers review it and offer corrections. You do the same for people learning your native language -it's reciprocal.

The Japanese course is noticeably smaller than Busuu's European language offerings, and the AI review feature (Busuu's attempt to compete with AI apps) is basic compared to dedicated AI language apps. The speech recognition is mediocre, and the lessons can feel formulaic. Community corrections are hit-or-miss -sometimes thoughtful and detailed, sometimes just a checkmark with no explanation.

Best for: Social learners who like the idea of human feedback on their output and want a structured curriculum with some community interaction.

Price: Free basic version with limited access; $9.99/month or $69.99/year for premium.

15. Tandem -Language Exchange App

Tandem is similar to HelloTalk -a language exchange platform connecting you with native Japanese speakers. You chat via text, audio messages, or video calls. The app has built-in translation and correction tools, and a "topic" feature that suggests conversation prompts when small talk runs dry.

Tandem's interface is slightly more polished than HelloTalk's, and the matching algorithm seems better at connecting people with compatible goals and interests. You can filter for partners who want structured language exchange versus casual chat, which helps. The app also offers professional tutors (paid), though this overlaps with what italki does better.

The same core problems apply: finding good language partners is competitive (many Japanese users get overwhelmed with requests from English speakers), conversations require self-direction and effort, and it's easy to end up teaching English more than learning Japanese. You need to be at least intermediate level to benefit, and you need thick skin to keep messaging people when most don't reply.

Best for: Intermediate learners who want free conversation practice and are willing to put in the work to find and maintain language exchange partnerships.

Price: Free; $6.99/month for pro features (unlimited translations, verified badge, priority in searches).

How to Choose the Right App for Your Japanese Learning Goals

The "best" Japanese learning app depends entirely on your goals, current level, and learning preferences. Here's a practical framework:

If you want to speak Japanese conversationally: Start with an app that forces speaking output from day one. Most learners waste months on passive input before attempting to speak. Apps like Victor AI's 60-Day Challenge -two missions per day, 10-15 minutes total, with instant corrections on every sentence -build conversational ability faster by focusing on production. Supplement with grammar study (Bunpro) and kanji (WaniKani) as needed.

If you want to read manga, light novels, or Japanese websites: Prioritize kanji with WaniKani or a dedicated Anki deck (Core 10k + kanji), then add grammar study with Bunpro or LingoDeer. Speaking practice is optional for this goal. Expect 1-2 years of daily study before you're reading novels comfortably.

If you're preparing for JLPT exams: Stack Bunpro (grammar), WaniKani (kanji/vocab), and a JLPT-specific Anki deck for your target level. JapanesePod101 has JLPT-focused content as well. Practice all four test sections (listening, reading, grammar, vocabulary) systematically. Apps focused on conversation are less useful here.

If you're an absolute beginner and unsure if you'll stick with it: Start with Duolingo or LingoDeer to learn hiragana, katakana, and basic phrases with low commitment. After 2-4 weeks, if you're still interested, upgrade to a more comprehensive system. Don't spend money on expensive apps or tutors until you've proven to yourself you'll practice consistently.

If you're an anime fan who wants to understand without subtitles: Focus on listening comprehension (JapanesePod101, Memrise) and conversational vocabulary (Victor AI, italki). You'll pick up casual speech, slang, and colloquialisms. Kanji is less urgent unless you also want to read manga. Be aware that anime Japanese is often exaggerated and not appropriate for real-life formal situations.

If you're learning Japanese for business: You need formal speech, keigo (honorific/humble language), and business-specific vocabulary. Pimsleur's business Japanese, italki tutors specializing in business contexts, and JapanesePod101's business lessons are your best bets. Victor AI's conversation mode includes formal speech practice, which is essential. Avoid apps that only teach casual Japanese.

The harsh truth: no single app will get you to fluency. Japanese is a Category IV language requiring 2,200+ hours of study. The most effective learners stack tools: one for kanji, one for grammar, one for speaking, and one for listening. They practice daily, stay consistent for years, and seek out real conversation practice once they have a foundation. Apps are tools, not magic solutions.

Frequently Asked Questions

Can I learn Japanese with just an app?

Technically possible, but unlikely to achieve true fluency. Apps are excellent for building vocabulary, learning grammar rules, practicing pronunciation, and developing basic conversational ability. But reaching advanced fluency requires authentic input (Japanese TV, books, podcasts) and output (conversations with native speakers, writing practice). Think of apps as structured training wheels that get you to intermediate level, at which point you need to supplement with real-world Japanese content and conversation. If your goal is traveling to Japan and having basic conversations, an app can get you there. If your goal is reading Murakami in Japanese or working for a Japanese company, you'll need more.

How long does it take to learn Japanese?

The U.S. Foreign Service Institute estimates 2,200 classroom hours to reach professional working proficiency in Japanese (ILR Level 3 or roughly JLPT N1). If you study 1 hour daily, that's 6 years. If you study 2 hours daily, that's 3 years. Conversational proficiency (JLPT N3-N4) comes much faster -600-900 hours, or 1.5-2.5 years at 1 hour daily. These are averages; your mileage varies based on prior language experience, study methods, and natural aptitude. Learning three writing systems (hiragana, katakana, 2,136 jōyō kanji) alone takes most learners 6-12 months of focused study. The key insight: Japanese requires sustained, consistent effort over years, not months. Apps that promise "fluent in 3 months" are lying.

What's the best free app for learning Japanese?

Duolingo is the most comprehensive free option for complete beginners, covering hiragana, katakana, basic grammar, and vocabulary at no cost (though with ads and limited features). For kanji specifically, WaniKani's first three levels are free and give you a taste of the system. Anki (on desktop and Android) is free and infinitely powerful if you're willing to learn how to use it and find or create your own decks. HelloTalk and Tandem offer free language exchange, though they require intermediate level to be useful. The reality: truly free apps get you to beginner level, but reaching intermediate and beyond requires paying for something -whether that's a premium app, textbooks, tutors, or living in Japan.

Is Japanese harder than Chinese or Korean?

For English speakers, Japanese and Chinese are both Category IV (hardest) languages according to FSI, requiring approximately 2,200 hours. Korean is slightly easier at 2,200 hours as well but often feels more accessible because the writing system (Hangul) is much simpler -you can learn it in a few hours. Chinese grammar is simpler than Japanese, but Chinese has tones (four tones in Mandarin, nine in Cantonese) that English speakers find difficult, and Chinese characters (hanzi) must be memorized without phonetic hints. Japanese grammar is more complex than Chinese, especially the politeness system (keigo), but pronunciation is easier (no tones, consistent sounds). Japanese kanji can be pronounced multiple ways depending on context, which is its own nightmare. The honest answer: they're all hard in different ways. Pick based on your goals (where you want to travel/work, what media you want to consume) rather than difficulty, because all three require years of study.
