The Tangoubukan was founded in August 2014 to provide a venue for martial artists to study and train in  Naginata. Its name comprises the following Japanese characters: 鍛 (tan, to forge, to train), 剛 (gou, strength, indomitable), 武 (bu, martial), and 館 (kan, hall). The characters were chosen to evoke the idea of a martial arts hall where a strong spirit is forged through Naginata training. 

Its students are currently small in number, but among them are active members of the San Jose State University Kendo and Naginata Club as well as current and former members of the US national naginata team. They all have in common a passion to practice, share, and promote this little-known martial art to the general public.

The Tangoubukan is part of the Northern California Naginata Federation (NCNF), the regional arm of the US Naginata Federation (USNF). The USNF represents the United States in the International Naginata Federation (INF).
