This is a pioneer inn in Akasawa-shuku along with Osaka-ya, and it still serves as an inn. The first floor of the building was built in the Tempo Period (1831-1845), and the second floor was added in the early Meiji Period. It is a traditional Kochu-yado, inn for worshippers The first floor has an L-shaped veranda called a mawari-doma (L-shaped earthen floor) where many guests can take step out of their Japanese sandals at the same time. Many tags with the name of the group, addresses, and individual names written on them (called itamanegi) are hung under the eaves. The oldest itamanegi tag in Akasawa-shuku was for a group of Myoho-ko worshippers in 1875 that can still be seen at Edo-ya Inn. Many kochu tags for worshippers are affixed on the ceiling in the drawing room. They show how busy it was at the time.
