What hachimaki means
Hachimaki is the thick band of plaster run around the top of the walls of a clay-walled storehouse just below the eaves; the name, meaning headband, is said to come from the way it encircles the top of the building. A storehouse is sealed in clay and lime plaster from wall to eave soffit, but the junction of wall and eaves is prone to cracks and gaps, and the hachimaki thickens and strengthens it against fire and rain.
It is also part of the design. A band of black plaster on a white wall, or a band built out in steps, sharpens the outline of the storehouse. It may be combined with a stepped Nokijabara, and the two terms are sometimes used loosely for the same zone.
Reading the records and the building
Records describe the band and its finish. The tool storehouse of the Tanaka family in Hirakata, Osaka, has plastered walls with tall vertical boarding at the base and a hachimaki under the eaves. A storehouse of the former Marunaka Yokonaka shop in Nagai, Yamagata, contrasts its white walls with a north wall and surrounding hachimaki in black plaster. The archive storehouse of Nagano Meijo in Chikuma has black plaster walls with a drip moulding and hachimaki, and the archive storehouse of Shioya Brewery in Suzaka uses black plaster on its window frames and hachimaki.
On site, look at the wall just below the eaves. A band projecting a step beyond the wall surface and running all round is the hachimaki; its colour and number of steps vary and reflect the plasterer's craft.
