What azumadachi means
Azumadachi is a farmhouse form common in western Toyama Prefecture, especially the Tonami area. The main house is entered from the gable end (Tsumairi) under a large gabled roof, with the gable turned to the front to display a broad triangular wall. The gable wall is said to show a grid of beams, through-ties and posts against white plaster. Records usually write the name in katakana.
Lower lean-to roofs, Geya, typically run round three or four sides, with the gable wall of the main roof rising above them. The form was used for the houses of wealthy farmers and for residences meant to convey standing.
Some have inside a construction called wakunouchi, a main room framed by heavy posts, beams and ties set like a frame, which gives azumadachi houses a distinct regional character.
Reading the records and the house
Records describe houses as so-called azumadachi. The former Otani family house in Oyabe, Toyama, seven bays across its gable front and four and a half bays deep, gabled, pantiled and gable-entry with one-bay lean-tos on three sides, is described as a so-called azumadachi house befitting a residence of the district. The main house of the Okuno family in Tsubata, Ishikawa, was moved there from western Toyama; it is recorded as a large azumadachi farmhouse whose main room behind the formal entrance uses the wakunouchi method with many heavy ties.
In a gable-entry building the front width is the dimension across the ridge. At the Otani house that is seven bays, wider than the depth of four and a half, and the figures themselves show a broad gable wall presented to the front.
On site, look at the great gable wall at the front. White plaster framed by a grid of timber, with lean-to roofs running beneath, marks the form. Some houses have been moved, so check the record rather than judging from location alone.
