JapaneseMod - Learn Japanese while you play Minecraft

Beta!

A Minecraft companion that actually speaks Japanese back — grammar, listening, and a friend who never runs out of patience.

A collab mod by Masa (Comprehensible Input Japanese) & Ubonga

JapaneseMod is a free Minecraft mod (Java Edition, Fabric) that teaches you Japanese while you play. You talk to an in-game companion out loud; it answers in natural Japanese, names the blocks and mobs around you, and explains grammar the moment you ask.

The mod

Not a translator. A tutor.

Everything below is a real, shipped feature — not a roadmap.

🗣️

Talk to it, out loud

Push-to-talk voice chat in-game, with a companion that answers in natural Japanese and English support.

⛏️

Learns from what you do

Say the name of the block you're holding, the mob nearby, the thing you just crafted — it's grounded in your actual game state.

📖

Grammar that sticks

Built-in grammar and reading tools surface the pattern behind a sentence the moment you ask about it, mid-game.
