Taikai App

Kenji Nakata

About this app

Taikai is the companion app for karate tournament day — built for the families, coaches, officials, and directors who live the six hours around four minutes of competing.

★ KNOW THE MOMENT THEY COMPETE
See your athlete's next division, mat number, and estimated start time, updated live as the event runs. Get a notification the moment they're called — never miss the match you came to see.

★ ONE TAP TO EVERYTHING
• Digital check-in badge — a scannable QR you show at the door
• Live results and placements as they're posted
• Watch live scores from any ring in the venue
• A timestamped feed of match calls, results, approvals, and schedule changes

★ FOR THE WHOLE FAMILY AND TEAM
Follow every competitor on your account, and — if you coach — see your whole dojo's athletes, mats, and who's up next on one screen.

★ RUN YOUR DOJO
Create your dojo, manage your roster, and approve join requests from your phone.

★ FOR OFFICIALS, STAFF, AND DIRECTORS
Judges, coaches, and staff carry their own credentials and check-in badges. Directors approve role requests and scan competitor and staff badges with the built-in check-in scanner — no laptop required.

★ FIND YOUR NEXT TOURNAMENT
Browse the karate tournament directory, view event details, and register on the web when you're ready.

Made for karate — kata and kumite, WKF and AAU formats. Registration and payment happen on taikaiapp.com.
