There is a large area (about 162 m2) where the floor was hardened with the soil.
About one-third of the building’s area is the soil in the Egawa House.
It was used as a kitchen and workplace.
You can see the kitchen kilns, the cannons, and the main pillar.
The cannon exhibited beside the kiln is a boat-haw whistles gun that was made in the United States in the latter half of the 19th century.
It was awarded to the Tokugawa shogunate from Perry in 1854. (However, barrels and shells are replicas in the Exhibit.)
This Doma Floor is the room where the dry bread was baked the first time in Japan.
As Hidetatsu is well known for manufacturing the long life breads for the Japanese.
