Hon-jin was a lodging used by feudal lords in Edo era. Miyaichi was a stage of both Sanyou Road and Hagi Road in Mouri-han and Koube managed the hon-jin. While a lord was staying at hon-jin, the main part of hon-jin building was occupied as a dwelling of a lord and followers and cookroom. The spare house that Koube family could use while a lord was staying was not prepared. Lords entered this hon-jin by way of the garden in front of the main room, Gozama. So, Genkan was not used as an entrance of lords.
