The guest house on Rokkenjima, also known as the Toraian (渡来庵), is where the younger members of the Ushiromiya family reside during the family conference. The guest house was originally built by Krauss Ushiromiya as a hotel in a failed attempt to convert Rokkenjima into a resort. The guest house has two stories and the doors of the house can be locked from the inside.
