KEY WORD :@architecture / folk dwellings

1@The posts which support the ends of the principal transverse beams *jouyabari ã‰®—À, in the main structural frame of traditional vernacular houses *minka –¯‰Æ, with thatched roofs. In cases where the roof was carried down beyond the ends of the jouyabari to create a lower peripheral zone *geya ‰º‰®, they were also called irikawabashira “ü‘¤’Œ. When the geya space was incorporated into the interior of the building, jouyabashira were often left as freestanding posts *dokuritsubashira “Æ—§’Œ. These were found to be inconvenient and carpenters devised various ways to eliminate them, most notably by inserting deep section lintels, sashimono ·•¨ or sashigamoi ·Š›‹ (see *kamoi Š›‹), which spanned from posts at the center of the building to the peripheral posts or *geyabashira ‰º‰®’Œ. They also supported the upper stub of the jouyabashira which was reduced to a strut *tsuka ‘©. jouyabashira usually define the boundary between the jouya and geya, but in certain cases, the situation is ambiguous because the ends of the jouyabari project beyond the line of the jouyabashira.

2@In fishermen's houses gyoka ‹™‰Æ, in Niigata prefecture, a large post that was placed at the boundary of the earth-floored area *doma “yŠÔ, and the living rooms, kyoshitsubu ‹Žº•”, approximately at the center of the building's cross section. See *daikokubashira ‘单’Œ.
