Okinawa is the birthplace of self defense karate.

We trace our lineage back to the recognized father of traditional Okinawan karate: Sokon Matsumura (1809-99), a personal body guard to the last three Okinawan Kings who named his self defense techniques Shuri-te. Shuri being the Okinawan capital. Te meaning hand. Another name used is Sui-de, or "our hand". Matsamura was also widely known as Bushi Matsamura, or Warrior Matsamura.   

Anko Itosu (1831-1915) was one of Matsamura's most famous students.  He also studied with Gusukuma (unrelated to the one mentioned below)  He also used the name of his karate as: Shuri te (Shuri hand) and taught:

Shinpan (Shiroma) Gusukuma (1890-1954) was a school teacher and acupunturist.  He was well known for his sturdy, powerful karate even though he was small in stature.  Okinawan Shuri-te evolved from Gusukuma's senior students.

Choshin Chibana(1886-1969) was known as the ultimate karate expert on Okinawa and taught a wide range of students.  Many of his students developed their own karate schools. Chibana called his karate: "Kobayashi", yet others called it "Shorin ryu".

Katsuya Miyahira, Hanshi, 10th Degree (1918-2010) studied longer with Chibana than any other student. In 1948 Miyahira named his karate school or dojo: Shidokan.  Shidokan means "Warrior Way", "Right Way", "Heart Way" or "Gentleman's Way".  Chibana relinquished his karate association duties to Miyahira before his death.

Seikichi Iha, Hanshi, 10th Degree, was Katsuya Miyahira's senior student.   Iha Sensei's name is still listed in rank order right after Katsuya Miyahira's name in the Shidokan Dojo Rank Board in Okinawa as of 2017 long after Miyahira's death.  (See photo below)

Iha began his karate studies with his uncle and then with Shinpan (Shiroma) Gusakuma in 1950. When Gusukuma died in 1954 he then began studying at the Shidokan Karate Dojo with Katsuya Miyahira.

Seikichi Iha received his 10th Degree in 2001.  Iha began teaching in the Original Okinawan Karate school/dojo in 1975 in Lansing, Michigan and continues to teach there even today.  Upon receiving his 10th Dan he named his Association Beikoku Shidokan.  Beikoku meaning American, so it means American Shidokan.   

Virginia okinawan karate dojo members
The Alexandria Karate Dojo reports directly to Grand Master Seikichi Iha, Hanshi, 10th Dan, an internationally reknown Okinawan Shidokan Shorin Ryu Karate Master and one of the senior-most Karate Masters in Okinawa. We follow his Beikoku Shidokan Shorin Ryu curriculum. Sensei Iha visits us in Alexandria at least once per year and we attend his seminars throughout North America and Asia.

Our senior instructor, Robert Roberto Curtis, 8th Degree, Kyoshi, has been a direct student of Seikichi Iha since 1979. He began his martial arts journey in 1969 practicing Judo, Kung Fu, Shotokan and Shorinkan karate before beginning training directly with Sensei Iha. During long term overseas diplomatic assignments he taught karate self defense to US Embassy Personnel, US Marines, foreign security operatives and people like you.

Robert Roberto Curtis is a member of the East Coast Regional Beikoku Shidokan Black Belt Testing Committee as well as the National Black Belt Testing Committee. He teaches self-defense seminars and is sought out for individual or small group self defense training and to provide proven effectives self defense applications found in other martial arts styles' katas and movements. 

We focus on proven effective self-defense karate applications.  Surviving an unexpected violent encounter while learning the beautiful, gentle art of Okinawan Karate body movements motivates our training.  Big egos, trophies and competition are for other schools. 

We welcome black belts and students from other karate and martial arts styles.
