About 2hongo
A comprehensive Japanese learning companion — combining the depth of a dictionary with the intelligence of a learning system.
Our Mission
To provide Japanese learners — from early stages through advanced proficiency — with the most comprehensive, context-rich dictionary and learning platform available. We believe effective language learning requires more than isolated definitions. It demands real-world context, systematic review, and instant access to the reference materials learners need at every stage of their journey.

Comprehensive Dictionary
214,000+ entries with contextual example sentences, pitch accent, audio pronunciation, word relationships, and JLPT classifications.
Spaced Repetition
An intelligent review system using the proven SM-2 algorithm with swipeable flashcards, progressive reveal, and personalized scheduling.
Grammar Reference
400+ grammar patterns organized by JLPT level, each with formation rules, examples with interactive tokenization, and related content.
Stroke Practice
Animated stroke order playback and freehand drawing practice with real-time validation for hiragana, katakana, and kanji.

34+ learning pages covering writing systems, verb conjugation, essential vocabulary, and quick-reference tables — all fully localized.
Language Tools
Text parser, full-width/half-width converter, kana converter, and Japanese era converter — handy utilities for daily study.
Our Story
2hongo was born from a simple frustration: existing Japanese learning tools lack depth. Traditional dictionaries give definitions without context. Flashcard apps offer review without reference. Grammar sites explain rules without vocabulary integration. Learners are forced to juggle multiple apps and websites, creating a fragmented, disjointed experience.
We set out to build something different — a unified platform where looking up a word leads naturally into understanding its grammar, practicing its writing, and adding it to a personalized review schedule. Every feature connects to every other, so learning flows instead of fragmenting.
With one of the largest Japanese-English/Chinese dictionaries available, 2hongo combines breadth with depth — contextual example sentences, interactive tokenization, grammar detection, and stroke validation — to create a learning experience that complements textbooks, courses, and classroom instruction.
Built for Global Learners
Language learning shouldn't be limited by which language you speak. 2hongo is fully localized in English, Chinese (Simplified & Traditional), and Japanese — not just translated UI, but culturally appropriate content and professionally translated learning materials throughout.
Generous Free Tier
Core features — word lookup, grammar reference, learning pages, stroke practice, and language tools — are free for everyone. Create an account to save words, build notebooks, and review with spaced repetition. Some advanced features and expanded limits may be available through a future premium plan.
The Team
We are a small team of passionate developers and language learners dedicated to improving the Japanese learning experience. We use 2hongo ourselves every day, and that personal investment drives the care we put into every feature.
