Mission: To preserve and teach the traditional martial arts of Japan (including Okinawa). We strive to accomplish this in an environment free of intimidation, politics, and other distracters. We further seek to foster a spirit of fellowship and understanding, welcoming all like-minded individuals, regardless of race, gender, ethnic background, religion, national origin, or physical handicap.

Vision: Build healthy minds, bodies, and spirits through the study of traditional martial arts.

Motto: One World – One Dentokan – One Family

Dentokan Logo: The Imperial Regalia of Japan, also known as the Three Sacred Treasures of Japan, consist of the Kusanagi sword, the Yata No Kagami mirror, and the Yasakani No Magatama jewel. The regalia represent the three primary virtues: Valor (the sword), Wisdom (the mirror), and Benevolence (the jewel). These three items have been a part of the Emporer's imperial enthronement ceremony since 620 [Source: Kido Koichi Nikii, Tokyo, Daigaku Shuppankai, 1966, pp. 1120-21]. This is a long standing tradition which is at the heart of the Japanese nation and its culture.

For centuries depictions of the Yasakani No Magatama jewel have appeared on Japanese family crests, cultural symbols, and business logos. It is regarded as a symbol of the human spirit, and is considered good luck by many. We have it at the core of our Dentokan logo as a way of symbolizing all things truly traditional as it relates to Japanese Budo/Bugei. Benevolence, the underlying meaning, reflects the Dentokan's mission of bringing traditional martial arts to everyone regardless of their ability to pay, cultural backgrounds, ethnic origins, nationalities, religious persuasions, physical handicaps, etc.

We chose the color purple for the Yasakani No Magatama jewel depiction because it is considered an imperial color in Japan. The green background symbolizes eternity or forever, meaning that through us the traditional martial arts of Japan will continue into the future.

The Dentokan Logo is registered with the United States Patent and Trademark Office (USPTO), Application Serial Number: 85077661.

Arts Represented: Shorin-Ryu Karate-Do, Goju-Ryu Karate-Do, Okinawa Kobudo, Ju-Jutsu/Aiki-Jutsu, and Iai-Jutsu/Batto Do.

Membership/Affiliation: The Dentokan is largely made up of students of Sensei Hobbs, and their students. Others wishing to join should seek out a Dentokan dojo, attend one of the Dentokan's regularly scheduled international courses, or sponsor a Dentokan Shihan to visit one's dojo. Membership/affiliation cannot be granted without first having one's technique evaluated. For more information please contact Sensei Hobbs (see below).

Reorganization: Some parts of the worldwide Dentokan were reorganized in late 2012, and early 2013. This resulted in some Dentokan members being asked to leave or being expelled. This has enabled the Dentokan to better enact its vision, to reduce the technical variances, to preserve the strong lineages of our traditional martial arts, and streamline operations.
