According to temple legend, the Tai-an Teahouse was originally a two-tatami mat sized fixed hearth teahouse built by SEN no Rikyu at the camp of Hideyoshi TOYOTOMI during the Battle of Yamazaki in 1582 which was then disassembled and relocated to its current site.
寺伝には、1582年の山崎の合戦のおり豊臣秀吉の陣中に千利休により建てられた二畳隅炉の茶室を解体し移築したとある。
