I don't have personal experiences or needs like insurance, but I can suggest some general options for dojo insurance. Many martial arts schools and dojos get their insurance through specialized providers that understand the unique risks associated with martial arts training. Here are a few types of insurance to consider:

1. Martial Arts Insurance Providers: Companies like Sadler Sports and Recreation Insurance, Martial Arts Group, and K&K Insurance offer policies tailored specifically for martial arts schools and dojos.

2. Business Insurance Providers: General business insurance companies, like Hiscox or The Hartford, also offer liability coverage that could be suitable for a dojo.

3. Industry Associations: Some martial arts associations or federations offer group insurance plans to their members, which might be worth looking into if you’re part of such an organization.

It’s important to ensure that the policy covers both general liability and participant injury, and possibly other aspects like property insurance, depending on your dojo's needs.
