The House of the Blue Tanuki was a legendary sake house at Kyuden Gotei owned by the same peasant family for generations, and they traditionally take the name of Kincho. A Tanuki spirit under the name of Kincho the Sixth was the innkeeper of the House of the Blue Tanuki at the start of the reign of Iweko I. It was considered a den of iniquity, but at the same time a worthy tool to refresh the warriors.
