Honolulu, Hawaii
Hawaii's judo scene runs through Shobukan and the broader Hawaii Judo Federation, with deep ties to Japan and a uniquely community-driven culture. Many dojos have been operating in the same spaces for 50+ years, with senseis whose lineage traces directly to early Kodokan teachers. The military presence (Pearl Harbor, Hickam, Schofield) adds a rotating contingent.
The local picture
Why it works for Honolulu
OLM's seminar billing handles registration, capacity caps, and a clean Stripe payout for high-cost mainland-instructor visits. PCS rotations carry verified Hawaiian-earned ranks to the member's next assignment intact. Multi-generational families use the guardian / dependent profile model — three or four family members under one billing relationship with separate kyu ranks and journals.
In every Judo gym, anywhere
Kyu and Dan tracking with promoter lineage
Every grading recorded with the issuing sensei, date, and context. If a student moves to another dojo that also runs OLM, their Dan rank lineage travels with them.
Attendance against grading minimums
Set mat-hour requirements per rank. OLM tells you who meets the threshold for their next grading and who's short.
Shiai & event registration
Stripe-powered sign-ups for tournaments and events. Members pay from the app, you get a clean registration list with waiver status.
Multi-discipline aware
A judoka who also trains BJJ keeps separate ranks per art. Cross-training students are first-class in the system.
