Seikichi Odo

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.

Seikichi Odo (born July 26, 1927 in Okinawa – died March 24, 2002), whose name means "world walker" in Japanese, was a karateka. He combined kobudō and karate techniques to found the Ryūkyū Hon Kenpo Kobujutsu Federation.

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 (1845–1915) and Chomo Hanashiro (1869–1945) were the karate instructors. Itosu Ankō (1830–1915) as well as Kentsu Yabu (1863–1937) 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".

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, Shinpo Matayoshi and Seiki Toma. At 23 Odo began to study karate under Shigeru Nakamura. Odo studied both kobudō (with Mitsuo Kakazu) as well as karate and kobudō with Seiki Toma, who was a student of Zenpo Shimabukuro who was taught by Chōtoku Kyan (1870–1945). Odo considered Nakamura as his primary instructor as well as mentor.
