Read Japanese with confidence, right on the page.

BunSense helps you understand Japanese text as you read. It adds furigana to kanji, provides instant translations, and explains grammar directly on any website, so you can stay focused without switching tabs or apps.

The name BunSense comes from 文 (bun), meaning “sentence” or “text,” and sense, meaning “understanding” or “intuition.” It reflects the idea of developing a natural feel for Japanese through real reading.
