Oshiro Dojo is the world headquarters (honbu) of the Ryukyu Bujutsu Kenkyu Doyukai (RBKD), an international organization dedicated to the study and development of traditional Okinawan martial arts. All RBKD member schools include Yamanni-ryu kobujutsu in their curriculum, typically alongside one or more empty-hand styles of martial arts. Oshiro Dojo classes are taught by experienced instructors who have practiced and taught martial arts for decades.
The Ryukyu Bujutsu Kenkyu Doyukai (Society for the Study of Okinawan Martial Arts) was founded in 1985 by Master Chogi Kishaba in Okinawa and Shihan Toshihiro Oshiro in the United States for the purpose of studying and developing traditional Okinawan karate and kobujutsu technique. Oshiro Dojo was founded by RBKD Chief Instructor (Shihan) Toshihiro Oshiro after he emigrated from his native Okinawa in 1978 to teach karate in the United States, and over the next 40 years he trained hundreds of students from across the country and around the world at his Northern California dojos. In late 2019, after moving back to Okinawa, Shihan Oshiro appointed his longtime student Daiki Takekawa, who has trained with him for over 25 years, as head instructor (Dojoshu) of Oshiro Dojo San Mateo.
Oshiro Dojo teaches in a friendly, non-competitive environment, with beginner and advanced classes for adults and children ages 5 and up. A typical class focuses on either kata (forms) or kumite (sparring). Shihan Oshiro visits the San Mateo dojo a couple of times each year and teaches group classes and private lessons during those times, and he teaches privately in Okinawa while continuing to lead the worldwide RBKD organization. Today the RBKD includes active member dojos around the world, including in the United States, Europe, and Japan, and Shihan Oshiro teaches many seminars each year around the world.
