2hongo

Look it up, understand it, save it, review it — in one app. 200,000+ entries, camera lookup, JLPT N5-N1 vocabulary and grammar, kana and kanji practice, and Sensei AI.

Japanese study works better when your dictionary, lessons, practice, and review schedule stay connected.

2hongo is an all-in-one companion for learners from their first hiragana to advanced JLPT study. Look up a word, understand it in context, save it, and review it later without switching between apps.

What you can do

Dictionary and search

Search more than 200,000 Japanese dictionary entries with readings, localized meanings, audio, example sentences, related words, and conjugation tables. Meaning search lets you describe the word you are looking for in your own words, even if you do not know its spelling.

Camera lookup

Scan Japanese with your camera or a photo. Recognition happens on your device, so the image never leaves your phone. Tap recognized words to open them in the dictionary.

Reviews, kana, and kanji

Remember vocabulary with swipeable spaced-repetition flashcards, personalized scheduling, streaks, and progress tracking. Learn hiragana, katakana, and kanji with audio, quizzes, mastery tracking, animated stroke order, guided tracing, and memory drawing.

JLPT grammar and reading

Study vocabulary from JLPT N5 to N1 and explore more than 470 searchable grammar patterns with clear formation rules and contextual examples. Read graded Japanese articles with tappable words, grammar highlighting, translation, audio narration, and comprehension quizzes.

Personalized guidance

Follow a daily plan from Sensei, personalized to your level, goals, weak areas, and available study time. Ask Sensei AI questions while viewing a word, grammar point, article, or basics lesson, so the answer already understands your context.

Your own study system

Organize saved words in custom notebooks and keep your study progress synced across devices. Use practical tools for Japanese text parsing, kana conversion, full-width and half-width conversion, and Japanese era dates. Review reminders open directly into the items due that day.

Built for real study

Use 2hongo alongside your textbook, class, or self-study routine. Study in English, Japanese, Simplified Chinese, or Traditional Chinese. The app follows your device language, supports light and dark themes, and includes grammar browsing plus selected tools that continue to work offline.

2hongo is free to use, and you do not need an account to look up words — every meaning, example sentence, and conjugation table is open to everyone. A free account adds saved words, notebooks, review scheduling, audio, JLPT N5 and N4 vocabulary and grammar, and your daily Sensei study plan. Some advanced content, subscription features, and higher AI usage limits require an optional Premium or Pro plan.

Subscriptions

Premium and Pro are optional auto-renewing subscriptions, and either plan can start with a 7-day free trial.
