About Us

NPO Triton Arts Network (TAN) was founded by people in and around Triton Square with the missions to promote both arts and community activities. Having the Dai-ichi Seimei Hall as its home for arts activities, NPO Triton Arts Network contributes through arts and community activities expanding chances for social education, revitalizing communities, promoting arts and cultural activities, and preparing a safe and sound environment for children.

TAN was approved as a non-profit organization by the Tokyo Metropolitan Government in April 13, 2001.

In 2009, Dai-ichi Life Insurance Company won the Grand Mécénat Award in Japan Mécénat Awards for their support of the music activities of NPO Triton Arts Network at Dai-ichi Seimei Hall.
