We read everything. Email hello@judoclasses.net and we'll get back to you — usually within a couple of days.

Listing corrections

Spotted wrong hours, a dojo that's moved, or one that's closed for good? Include the dojo name and city and we'll fix it in the next data refresh. If a listed business shouldn't be here at all — it doesn't actually teach judo — tell us and we'll remove it.

Dojo owners

Own a dojo in the directory? Claiming your listing is free — email us from an address at your dojo's domain (or your dojo's public social account) and we can correct details, update hours and photos, fix your listed classes and disciplines, add your free-trial or schedule link, and mark your listing as owner-verified.

Not listed yet? Send your dojo name, address, and website and we'll review it for inclusion. We list dojos and clubs open to the public that teach judo — dedicated dojos, community and nonprofit clubs, and martial-arts schools with judo on the schedule.

Press & data

Want the dataset behind Judo Classes by the Numbers — the Judo Class Cost Index, the capitals, or the disciplines mix — for a story? Email us. We're happy to cut the numbers by state, metro, or discipline, with attribution.
