OUR ROOTS

SEIBUKAN SHORIN-RYU KARATE-DO

Our mission is to preserve, teach, pass down and further the art of traditional Seibukan Shorin-Ryu Karate-do as taught by the Shimabukuro family, honoring its roots of Okinawan culture, history in Okinawa, and perfection of technique.

HISTORY
 Okinawa, Japan, is the birthplace of modern-day karate and kobudo (weapons fighting). Historians believe these martial arts originated over 1,000 years ago, essential for the self-defense of the islanders. Throughout this thousand-year history, unarmed and armed defense techniques were influenced by contact with China and its martial arts systems.
Continual subjugation of the Okinawans by the Japanese and the banning of weapons on the islands further necessitated the practice of martial arts for safety. Due to the secrecy required, karate and kobudo were passed down from master to student through kata for hundreds of years. Sometimes, this teaching was comprehensive and spanned many years. Other times, teaching a kata might occur briefly, such as during a chance encounter.
Seibukan Shorin-Ryu is one of the many styles of Okinawan Shorin-Ryu that developed in the Shuri region in the 1800s. Also known as Sukunaihayashi, this traditional karate style was established in 1962 by Master Zenryo Shimabukuro, a student of the legendary Master Chotoku Kyan. Zenryo Shimabukuro cultivated his 11 years of training with Kyan into Shorin-Ryu Seibukan Karate-Do and built the Seibukan Karate School to preserve Kyan's powerful karate. This style requires power, precision, speed, and agility, with repetition of basic techniques and kata forming the foundation of training. Dedicated practice is a path to self-discovery and self-improvement. After Zenryo’s unfortunate passing in 1969, his son, Hanshi Zenpo Shimabukuro, continued in his father's footsteps to maintain and spread Shorin-Ryu Seibukan worldwide without changing the techniques his father learned from Kyan. Under Zenpo’s guidance, Seibukan Shorin-Ryu continues the legacy of its founder, Master Zenryo Shimabukuro.
"Seibukan is very traditional and steeped in Okinawan culture. It seeks precision in technique, strength and grace in the body, effectiveness in self-defence, and elevation of the spirit." ~ Sensei Doug Aoki, Head instructor, Seibukan Karate School, Edmonton CA - www.Nantanreikan.ca

In 1962, he established his own dojo, naming it Seibukan, which means "Holy Art School." This name soon came to represent the karate style itself, embodying Sensei Shimabukuro’s philosophy of karate. Highly respected in his community, he received numerous certificates of appreciation from city officials for his contributions to the betterment of the Okinawan people.In 1964, the All Okinawan Karate-do Federation awarded him the highest rank in Karate, the 10th Dan Red Belt.

EXTENDED HISTORY:

10th Degree Black Belt and Supreme Instructor* Hanshi Zenpo Shimabukuro, 10th Degree Black Belt and Supreme Instructor of the International Seibukan Shorin Ryu Karate Association, was born in Chatan Cho, Okinawa, in 1943. He was the fourth of five children of Master Zenryo Shimabukuro. Born during the tumultuous period leading up to World War II, he experienced significant loss, including the deaths of one sister at the war's onset and a younger brother shortly after its end. The war left the Shimabukuro family destitute, forcing them to relocate to northern Okinawa until the conflict subsided. Before World War II, Master Zenryo Shimabukuro was a baker and tatami maker. After the war, he briefly worked for the United States military before resuming his profession and also serving as a city government official. Hanshi Zenpo Shimabukuro helped his father teach Seibukan karate on US military bases and played a role in constructing the Seibukan Dojo in Jagaru. Hanshi Shimabukuro graduated from Futema High School in March 1962. In September 1963, at his father's request, he traveled to the United States to teach Sukunaihayashi karate-do to Seibukan students in Philadelphia, Pennsylvania, becoming one of the first Okinawan Sensei to teach karate-do in America. He returned to Okinawa in 1966 to assist his father with the Seibukan Honbu dojo and succeeded his father as Supreme Instructor upon his father's death in October 1969. In 1975, the International Seibukan Karate-do Association was formed. Sensei Shimabukuro returned to the United States for a three-month stay in Mississippi to meet with prominent American Seibukan Sensei and formalize the organization. His global visits to Seibukan students in America, Japan, Malaysia, Germany, Poland, South America, the Middle East, and India became essential for updating and standardizing karate techniques and katas. Fluent in English, he effectively shared his profound knowledge of karate-do with English-speaking karate-ka worldwide.
