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.

What We Offer

Everything you need to build, retain, and deepen your Japanese vocabulary — in one place.

Comprehensive Dictionary

214,000+ entries with contextual example sentences, pitch accent, audio pronunciation, word relationships, and JLPT classifications.

Structured Learning

34+ learning pages covering writing systems, verb conjugation, essential vocabulary, and quick-reference tables — all fully localized.

Stroke Practice

Animated stroke order playback and freehand drawing practice with real-time validation for hiragana, katakana, and kanji.

Curated Vocabulary

Thematic and JLPT-leveled word lists with filtering, sorting, and direct integration into your personal notebooks.

Grammar Reference

400+ grammar patterns organized by JLPT level, each with formation rules, examples with interactive tokenization, and related content.

Reading Articles

JLPT-leveled stories, conversations, and cultural pieces rendered as interactive text — every word is clickable and grammar patterns are auto-highlighted in context.

Notebook

Save words into your own notebooks, organize them with tags and personal notes, and review them with swipeable spaced-repetition flashcards.

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.

Free During Early Access

2hongo is completely free while in early access. All features — word lookup, grammar reference, learning pages, stroke practice, notebooks, spaced repetition, and language tools — are available to everyone at no cost. The core learning experience will always be free. To keep the project sustainable long-term, some advanced features may move to a paid plan in the future. Early supporters will be taken care of.

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.
