I recommend for all ages and skill levels. The technical level and experience of instructors and several of the students are like no other. A large number of them are international champions and more are getting ready for the challenge, like me. It is a traditional dojo, it is expected discipline, respect and hard work. Two things I think to be unique, first is the supportive environment (competitive yes, but it is like a big family of champions sharing their best) and the second is the intellectual teachings (origin of techniques, comparisons with other martial arts) which is making me sharper as a karate-ka and a person.
