We have various locations, but all currently in Leytonstone, East London. Most can be visited without advance notice. The addresses for these are on the jujutsu and karate class pages. Alternatively, you can email us. You may provide your phone number if you'd like a call-back. In case you're interested to know, in Japanese culture and especially martial arts, it is polite and respectful to address the teacher as 'sensei', and it goes a long way.
