Tatsuo learned Tensho, Seiunchin ("Seize-Control-Fight") kata and Sanchin ("Three-Fights/Conflicts") kata. Prior to studying with Miyagi, Shimabukuro, in 1942, sought out another famous Shorin-Ryu instructor, Choki Motobu, who was probably the most colorful of all of Shimabukuro's instructors. Motobu had had many teachers for short periods of time, including some notable ones such as Anko Itosu (Shuri-te), Sokon Matsumura, and Kosaku Matsumora (Tomari-te). Motobu was known for often getting into street fights in his youth to promote the effectiveness of karate. Shimabukuro studied with Motobu for approximately one year. Shimabukuro opened his first dojo in 1946 after the war in the village of Konbu, near Tengan village. From World War II until death Turning point Coming from a farming family, Shimabukuro had always been poor, but he was very innovative and opportunistic. He had a natural talent for adapting things. As a young man in Kyan (Chan) (チャン) Village, he discovered a way to bind tiles to the roofs of homes without using mud, which had been the traditional way. During World War II, as part of the Boetai, he was forced to help construct the airfield in Kadena with his horses and carts. During the October 10, 1944 bombing raid by the Allied Forces, he lost his horses and carts.

His interest in weapons (Kobudo) grew, and he sought out the most renowned weapons instructors, because he only knew the one bo (staff) kata, 'Tokumine no Kun' and basic sai techniques he had learned from Chotoku Kyan. He soon became a master in the Bo and Sai weapons. During the late 1950s and early 1960s, he continued his study of Kobudō with one of Moden Yabiku's top students, Shinken Taira. This training took place in Shimabukuro's dojo in Agena. He learned Hama Higa nu Tuifa, Shishi nu Kun, Chatan Yara nu Sai, and Urashi Bo. Shimabuku created Kyan Chotoku nu Sai and Kusanku Sai using sai techniques he learned from Chotoku Kyan. To honor Chotoku Kyan, he named his first sai after him. However, Kyan nu Sai was replaced by 1960 with Kusanku Sai. Creative years During the late 1940s Shimabukuro began experimenting with different techniques and kata from the Shorin-Ryu and Goju-Ryu systems as well as Kobudo. He first
