Learning Japanese is an exciting goal, but finding the right tools can feel overwhelming. Between paid subscriptions, expensive textbooks, and confusing apps, it is easy to waste time and money. The good news is that you do not need to spend a single yen to make real progress. This guide covers ten free and genuinely useful apps that will help you learn Japanese effectively. Each one offers solid features without hidden costs or gimmicks.
Before we dive into the list, remember that no single app will teach you everything. Language learning requires a mix of reading, writing, listening, and speaking practice. The apps below are chosen because they are reliable, regularly updated, and trusted by learners around the world. They work for beginners, intermediate students, and even advanced learners looking to sharpen specific skills.
Whether you are preparing for the JLPT, planning a trip to Japan, or just love anime and want to understand the original dialogue, these apps will give you a strong foundation. Let’s look at the top ten free and guaranteed apps for learning Japanese.
1. LingoDeer
LingoDeer is often called the best free app for Asian languages. Unlike many general language apps, LingoDeer was built specifically for Japanese, Korean, and Chinese. The Japanese course starts from hiragana and katakana, then moves into grammar and vocabulary. Each lesson explains sentence structure clearly, so you understand why a sentence is formed a certain way.
What makes it unique is the grammar notes. Most free apps skip detailed explanations, but LingoDeer provides short, simple notes after each lesson. You can review these anytime. The app also has a travel phrasebook and a flashcard system for reviewing words. The free version gives you access to the first few units of each level, and you can earn daily streaks without paying.
2. Anki
Anki is a spaced repetition flashcard app. It is completely free on desktop and Android (the iOS version has a one-time fee, but the web version is free). Anki lets you create your own decks or download shared decks made by other users. For Japanese, there are thousands of pre-made decks covering JLPT vocabulary, kanji by grade level, and common phrases.
The real power of Anki is its algorithm. It shows you cards right before you are about to forget them. This makes memorization much more efficient than traditional studying. You can add your own example sentences, images, and audio. Many learners use Anki alongside other apps to lock in new words.
3. Duolingo
Duolingo needs no introduction. It is one of the most popular free language apps in the world. The Japanese course is extensive and covers hiragana, katakana, basic kanji, and grammar. The lessons are short and game-like, which makes it easy to practice for five minutes a day. Duolingo now includes listening exercises, speaking prompts, and stories for Japanese learners.
While Duolingo alone will not make you fluent, it is excellent for building daily habits and learning common vocabulary. The free version includes ads, but the core features are fully accessible. Use Duolingo as a warm-up or a quick review tool.
4. Tae Kim’s Guide to Learning Japanese (App)
Tae Kim’s grammar guide is a classic resource. The official app is free and contains the complete grammar guide in a mobile-friendly format. It covers everything from basic particles to advanced verb conjugations. The app includes example sentences and practice exercises. There are no ads and no in-app purchases.
This app is not a game. It is a straightforward reference and textbook replacement. If you want to understand how Japanese grammar actually works, this is one of the best free tools available. Pair it with a flashcard app for vocabulary, and you have a powerful learning system.
5. Japanese Kanji Study (by Mindtwister)
Kanji can be intimidating, but this app makes it manageable. The free version lets you study a limited number of kanji per day, which is actually a good thing. It forces you to focus on a few characters at a time. Each kanji comes with stroke order diagrams, readings, and common vocabulary words. The app uses spaced repetition and quizzes to test your memory.
The writing practice feature is especially helpful. You trace the kanji with your finger, which helps you remember the shape and stroke order. The app also groups kanji by JLPT level and grade school level. If you upgrade to the paid version, you unlock all kanji, but the free version is more than enough for serious beginners.
6. NHK Easy News
Reading real Japanese news is a great way to improve, but regular news is too hard for beginners. NHK Easy News writes simplified news articles with furigana (small hiragana above kanji). The app is free and updates daily with current events. Each article includes a slow audio recording by a native speaker.
The vocabulary is practical and relevant. You learn words related to weather, politics, culture, and daily life. The app also highlights difficult words and gives you a built-in dictionary. Start by reading one article per day. Listen to the audio first, then read along. This will improve your reading speed and listening comprehension at the same time.
7. HelloTalk
HelloTalk is a language exchange app. You connect with native Japanese speakers who want to learn your language. The free version lets you chat, send voice messages, make corrections, and even call other users. It is not a structured course, but it gives you real-world practice.
You can post moments (like social media updates) and get corrections from native speakers. The built-in translation, transliteration, and text-to-speech tools help you understand messages. The key is to be active. Write a few sentences every day, ask questions, and help your language partners with their English or other languages. It is a two-way street.
8. Obenkyo
Obenkyo is a lesser-known but highly effective app for Android. It is completely free with no ads. The app covers hiragana, katakana, kanji, vocabulary, and grammar. It has a built-in drawing recognition feature for kanji practice. You can test yourself on stroke order, readings, and meanings.
The grammar section is particularly good. It explains Japanese grammar points with clear examples and quizzes. The app is a bit old-fashioned in design, but the content is solid. If you want a no-frills, all-in-one study tool, Obenkyo is worth installing.
9. Jisho (Dictionary App)
Jisho is the most popular online Japanese dictionary. The official mobile app is free and mirrors the website. You can look up words in English, Japanese, or by drawing kanji. It shows example sentences, common word combinations, and JLPT levels. The app also includes a radical search for finding unknown kanji.
Use Jisho whenever you encounter a word you do not know. It is faster than Google Translate and more accurate. The app works offline for basic searches, but you need internet for full features. Keep it open on your phone while reading or watching Japanese content.
10. Yomiwa (Dictionary with OCR)
Yomiwa is a dictionary app with optical character recognition (OCR). You can point your camera at Japanese text, and the app will identify the words and give you translations. The free version is limited in daily scans, but it is still very useful. It also includes handwriting recognition and a built-in flashcard system.
This app is perfect for reading signs, menus, manga, or book pages. Just snap a photo, and the app reads the text for you. It also gives you the pitch accent for each word, which helps with pronunciation. If you are in Japan or reading real materials, Yomiwa is a lifesaver.

How to Use These Apps Together
No single app will teach you everything. Here is a practical routine using several of these tools:
- Morning (5 minutes): Do one Duolingo lesson to warm up.
- Lunch break (10 minutes): Review 10 new Anki cards from your JLPT deck.
- Evening (20 minutes): Complete one LingoDeer unit, then read one NHK Easy News article with audio.
- Before bed (5 minutes): Chat with one language partner on HelloTalk or write a short post.
This routine uses five different apps and covers reading, writing, listening, vocabulary, and grammar. It takes about 40 minutes total and is completely free.
Frequently Asked Questions
Are these apps truly free with no hidden costs?
Yes. All ten apps listed offer a substantial free version. Some have optional paid upgrades (like Anki’s iOS app or LingoDeer’s full course), but you can learn effectively without spending money. Duolingo and LingoDeer show ads in the free version, but the ads are not intrusive.
Can I become fluent using only free apps?
Fluency requires active speaking and real conversation practice. Free apps can take you to an intermediate level (around JLPT N4 to N3). To become fluent, you will eventually need to speak with native speakers, write essays, and consume media like podcasts or TV shows. HelloTalk helps with speaking, but you should also consider joining a local conversation group or using a tutor for occasional paid sessions.
How long should I study each day to see progress?
Consistency matters more than hours. Aim for 20 to 30 minutes daily. Even 10 minutes every day is better than two hours once a week. With regular use of these apps, you can expect to learn basic hiragana and katakana in two weeks, about 300 common words in two months, and enough grammar for simple conversations in four to six months.
