This building is established in 1910 as a welfare facility of Kosaka Mine. This is a half-Japanese and half-Western style wooden theatre. A clapboard style is adopted in the front exterior. That is painted in white. There are double-hung windows and serrated decorations which are lined up regularly. About the interior, there are tulip-shaped lamps on the ceiling. As you can see the octagon framework inside, it can be said that it is an elaborate western-style building. The tradition of Edo period is remained strongly in the gallery, two stage passages, the cut-out hole, the revolving stage and so on. Even now, many customers enjoy the regular performances and Kabuki play by famous actors.
