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.

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.
