I am planning to study Japanese in Japan for about six months. I am thinking about training in the martial arts there. I will probably be studying near Tokyo. I am looking for a karate school, a jujutsu school or a school that teaches a jujutsu/karate hybrid because I have a brown belt in Kyokushin Karate and I will be tested for my brown belt next month in jujutsu (my current teachers teach a jujutsu/karate hybrid based on Kyokushin Karate and Genbukan Jujutsu). Have any of you every trained in Japan? If so, what schools can you recommend? I also heard that looking for a dojo in Japan is very different from looking for a dojo in the West. Is that true?
