It is presumed that this building constructed in the late 17th century is a house of

Mokushi (a government post in the Edo period which was in charge of maintaining ranches under direct control of

the bakufu, as subordinates of an officer in the bakufu), who managed the Koganemaki (a ranch where war horses were raised)

run by the Edo bakufu (Japanese feudal government headed by a shogun).
