This inn is located at the foot of the mountain at the Iwamura Castle ruins, which has been selected as one of Japan's 100 most famous castles and is one of the three major mountain castles. The exterior design is inspired by the Ninomaru area. The high atrium lobby has a gassho-zukuri style, and the large dining hall has thick beams, creating an atmosphere that takes you back to the Showa era.
