The Sekai Dentokan Bugei Renmei, Inc. (World School of Traditional Martial Arts Federation, Inc.) is an independent martial arts organization that seeks to preserve and promulgate the traditional martial arts of Japan, including Okinawa. It was founded in 1994 by Colonel (Retired) Roy J. Hobbs, Hanshi as a means of providing instruction, and certification, in the various martial arts he has studied for nearly 60 years. Hobbs Sensei holds senior grades in Okinawa Goju Ryu Karate Do, Okinawa Shorin Ryu Karate Do, Okinawa Kobujutsu/Kobudo, Nihon Karate Do, Nihon Jujutsu, Nihon Iaijutsu, and Toyama Ryu Iaido. All grades awarded by Japanese and/or Okinawa based groups.

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.
