Challenge your speaking skills in a unique sumo-style tongue twister game!
Speak each phrase correctly within the time limit to win the match. If you
finish speaking before the timer runs out—even if the pronunciation is not
perfect—you still pass the round. The key is speed, clarity, and rhythm!

Win enough matches in a tournament to move up the sumo ranks—from Jonokuchi
to Yokozuna!

■ Fun and engaging training
As your rank rises, the tongue twisters become longer and more challenging.
Improve your pronunciation, timing, and speaking speed naturally while
enjoying the game.

■ Voice recognition battle
Your voice is judged with real-time speech recognition. Speak clearly and
quickly to get a successful reading and claim the win.

■ Sumo ranking system
Each tournament has 15 matches. Achieve winning records to advance to higher
ranks and face harder tongue twisters.

■ Simple and intuitive design
Designed for all ages. Just speak into your microphone within the time limit
and enjoy the fast-paced rhythm of each match.

■ Perfect for language practice
Great for improving Japanese pronunciation, clarity, and reaction speed.
