Meibukan (明武舘) is a version of goju-ryu karate and was created by Sensei Meitoku Yagi (born in 1912). Yagi was a student of Goju-ryu's founder, Chojun Miyagi (and arguably his most sentior student as he was:

• passed Miyagi's belt (althouugh this was done ten years after Miyagi's death)
• the first student of Miyagi Sensei recorded to be given permission to open their own dojo (which he did in 1952)

Yagi Dai Sensei was a founding father of the Okinawa Goju-Kai and All Okinawa Karate-Do Association both of which the Meibukan Hombu Dojo has been actively a part of since their formation.

His style, Meibukan, translates as a name to"House of the pure-minded warrior." Meibukai practice Goju-ryu kata, as well as its own set of kata developed by Dai Sensei. Wikipedia states that Yagi Meitoku (in his late teens) was the first to learn the complete early set of Goju-ryu Kaishu Kata (Geki Sai Ichi, Geki Sai Ni, Saifa, Shisochin, Sanseryu, Seisan, Seienchin, Sepai, Kururunfa, Suparinpe). Yagi Sensei also adapted some of the Meibuken Kaishu kata to bō and sai, and are commonly referred to as Meibuken Kobudo
