1 A service or tradesmen's entry. A house entry that lead to the kitchen; *katte 勝手, *daidokoro 台所. The formal entry for guests was called *genkan 玄関. The family entry was called *uchigenkan 内玄関. The katteguchi was used particularly in late Edo period houses of middle ranking warriors, chūkyū bushi jūtaku 中級武士住宅 where the earth-floored area *doma 土間 was small and the kitchen entry often tucked away at the rear. In farmhouses nōka 農家 and in the houses of traders and artisans *machiya 町家 where the doma was more extensive and its entry more prominent, the term *ōdoguchi 大戸口 (great doorway) was commonly used for the main entrance.

2 Used in parts of Aomori Prefecture instead of ōdoguchi for the main entry to the doma in large-scale nōka which also had a genkan (here referred to as genkanguchi 玄関口).
3 In vernacular houses *minka 民家 in parts of Saitama Prefecture, a secondary entry to the doma distinct from ōdoguchi. Usually at the rear of the house or in the gable end, it was in close to the food preparation area.
4 In tea houses *chashitsu 茶室, either an alternative term for *sadōguchi 茶道口, the door dividing the chashitsu from the preparation area; *katte 勝手, *mizuya 水屋, or as an alternative entry to the katte from the exterior, as at Shōiken 笑意軒, Katsura Rikyū 桂離宮 in Kyoto.
