Of pechin descent, he was small in stature and introverted as a youth. At age 9 Odo began his martial arts training in judo. At age 13 Odo met Koho Kuba of Kawasaki, Okinawa. Kuba taught Odo the art of Okinawa-te. At the age of 20, Odo began to study Okinawan kobudō. He studied weapons arts diligently to ensure the preservation of the old ways. Odo's kobudō instructors included many of the leading practitioners of Okinawa, such as Mitsuo Kakazu, Kenko Nakaima, Shimpo Matayoshi and Seiki Toma. At 23 Odo began to study karate under Shigeru Nakamura. Odo studied both kobudō as well as karate and kobudō with Seiki Toma, who was a student of Zenpo Shimabukuro who was taught by Chōtoku Kyan. Odo considered Nakamura as his primary instructor as well as mentor.
Shigeru Nakamura
Nakamura was born on January 20, 1894. His karate training started whilst in attendance of Icchu Middle School in Shuri. It was here that both Kanryo Higashionna and Chomo Hanashiro were the karate instructors. Itosu Ankō as well as Kentsu Yabu also made visits to the school. After middle school, Nakamura returned to Nago city where he trained under Shinkichi Kuniyoshi. In 1953, Nakamura opened his own dojo in Nago city and called his form of karate "Okinawa kenpo". Seikichi Odo took over teaching in the dojo as Nakamura aged. Odo asked Nakamura if he would allow incorporating kobudō with karate teachings. Nakamura was hesitant to allow this, but in the end did. Odo incorporated Kobudo in the mid 1970s. In July 1983, Odo restructured the Okinawa Kenpo Karate-Kobudō Association, renaming it the Okinawa Kenpo Karate Kobudō Federation. In 1998 to ease derisiveness, Odo changed the federation name to the Ryūkyū Hon Kenpo Kobujutsu Federation. Odo's Ryūkyū Hon Kenpo Kobujutsu Federation teaches a total of 50 kata; 20 open hand forms and 30 weapons kata. As Odo said, "You keep, keep my kata straight".
Bogu Kumite
Bogu Kumite is a form of armored training used in some Okinawan kempostyles of karate. The origin of this unique training approach is credited to Shigeru Nakamura. Shorin-ryu, Chito-ryu, Isshin-ryu, Shorinji-ryu and Nippon Kempo also employ this training method. Bogu Kumite is a rough, full contact training method in which the participants are discouraged from using feints and jabs and are expected to throw full-power blows. Rules vary between practitioners, but a generally accepted norm is to only count strikes that would incapacitate the opponent, had they not been wearing the gear. Hits must land on the gear and on the steel cage of the mask.
Equipment
Bogu gear is made of pieces analogous to those of kendobogu. Men- steel cage mask that covers the anterior and lateral head, with an opening in back. It extends to the neck to provide a degree of control during heavy impacts. Kumite men usually have shorter neck pieces since they do not usually need to stop the heavy blows to the clavicle as with kendo armor. Kote- padded gloves, often of the Kempo variety with finger articulations. Do- semi-rigid chest protector made with several padded plates of various materials such as heavy plastic or light metals sewn into it. Participants also usually wear a groin protector, elbow pads and shin protectors as with other karate training methods.
