Opened in the corner of the warehouse area in Nanotsu, Fukuoka in December 2000, Sangosoko serves as a production space for young artists. Closed in April of 2011.

This place was offered by an anonymous benefactor living in Fukuoka who wishes to support culture development and who financially supports young artists there; a true story, like a modern version of “Daddy-Long-Legs". There are three studios on the first floor and two studios and an exhibition space on the second floor for artists who produce and exhibit their work. The studios are usually used as production spaces, but when a regular exhibition is held, it is opened to the public for viewing. It is a one of this gallery’s features to be able to observe the site of production while also viewing the exhibition itself. An artist, Sho Kazakura, took over as director between 2001 and 2007 and Tadaomi Sakai succeeded the position in 2008. Yumi Nagasaki is in charge of management. This is a place in which various kinds of people who share the same sentiments have come together and realized the establishment of this place through such volunteer work as redecorating the warehouse.
