Ota-ya in Higashi-Iwase was a lodging used by feudal lord for stay and rest in Kanazawa-Han and Honjin in Toyama was a similar lodging in Toyama-Han in Edo-Era. Through the examination of historical materials, following results were ascertained;
1)Ota-ya in Higashi-Iwase and Honjin in Toyama were both composed of two parts, rooms for lord and private rooms for dweller.
2)Honjin in Toyama had two sets of rooms for lord. Such a plan was uncommon among lodgings used by feudal lord in Japan in Edo-Era.
