The IKKU sets itself apart from other Traditional Karate Organizations through the extensive kata and bunkai exposure we offer our members in live dojo classes, seminars, weekend camps, and now via digital video formats. You will experience this early on with our Taikyoku Katas 7-10 offering. While most traditional organizations only have access to the Taikyoku 1-3 kata developed by Gigo Funakoshi, our Soke had exposure to an expanded Taikyoku Series (4-10) that Aihara Sensei developed after training directly with Funakoshi, Egami, and Izumikawa.
Kiyoshi Aihara (1932–2017), founder of the Zen Shoto Kai, Sensei Kiyoshi Aihara, a Waseda University graduate and direct student of Gichin Funakoshi, played a pivotal role in expanding the foundational training methods of Shotokan Karate. While Gigo Funakoshi developed the original Taikyoku Kata series (1–3) as introductory kata, Aihara recognized the need for greater progression between beginner and intermediate kata. Building on his teaching experience in Japan and later in Hawaii, he extended the series by creating Taikyoku 4–6 during his years at Waseda University in the early 1950s.
Taikyoku 7–10 (Shichidan–Judan) were developed and introduced by Sensei Kiyoshi Aihara between the late 1950s and early 1960s. As an extension of the simplified Taikyoku series, these kata added flowing directional complexity while reinforcing kihon. They became an early component of the beginner curriculum taught at the Butoku Karate Club in Honolulu and were later preserved and formalized within the IKKU system.
By the early 1960s, Taikyoku 7–10 were firmly integrated into the curriculum at the Butoku Karate Club and became staples among his students, including Soke Joseph Ruiz of the International Karate Kobudo Union (IKKU). These kata were a vital link between the more linear Taikyoku and the more complex Pinan series, effectively bridging gaps in coordination and flow for beginner-level practitioners. These kata were designed to expand the curriculum and challenge students with new embusen (movement lines), timing shifts, and directional transitions. Aihara’s unique approach emphasized balance, rhythm, and the “Odori” or dance-like flow characteristic of his advanced beginner forms.
Though less known outside of the IKKU and Aihara’s direct lineage, Taikyoku 7–10 remains a testament to his pedagogical innovation and creative legacy. They represent a functional yet graceful extension of the Shotokan system—forms that continue to be practiced, preserved, and passed on to future generations through Aihara’s students and the structured teaching systems they’ve maintained.
Due to the informal nature of kata transmission in the 1950s, Aihara’s contribution is not always widely cited in mainstream Shotokan texts. However, his students—including Soke Joseph Ruiz of the International Karate Kobudo Union (IKKU)—preserved and propagated these kata in Japan and Hawaii. Today, Taikyoku 4–10 remain essential to IKKU’s foundational curriculum and represent an innovative phase in Shotokan’s postwar karate evolution.
“These kata reflect Sensei Aihara’s deep understanding of how to gradually prepare students—not only physically but mentally—for the rigors of traditional Karate. They are elegant in their simplicity but powerful in their application.”
— Soke Joseph Ruiz, Founder IKKU
Soke Ruiz learned this kata series as a youth while studying under Aihara and has generously shared the kata knowledge with the IKKU members during previous seminars and camps. Our organization is lucky to have this elite Taikyoku Series to offer to our members.
We hope you enjoy the exposure to this rare traditional karate kata series.
