A Superb Edo Period Samurai Jingasa War Hat Helmet

A Jingasa Ichimonji Gasa, circa 1800. The clan mon [family crest] is very distinctive indeed. A lacquer over cloth and paper constructed helmet, as is traditional of the era. The most used and famous are the various round jingasa that are basically flat with just a small raised central part. Akemi Masaharu calls this type ichimonji gasa (straight-line hats), hira gasa (flat hats) or nuri gasa (lacquered hats). The vast majority of these are made in what Akemi Masaharu calls the dry lacquer technique. This would involve gluing layers of cloth and / or paper together into a wooden mould, perhaps with some thin wood or bamboo strips as reinforcement, until a sufficient thickness was obtained, then lacquering. An alternative was to make them from coiled twisted paper strings, with each turn sewn to the next with another string. When lacquered, the whole structure was stiffened sufficiently to hold its shape. In both cases the result is a lightweight basic shape that could be individualised with decorations in lacquer. Not all of these are made in this way. Most ichimonji jingasa are black lacquered on top with the owner's, or his lord's, kamon in gold on the front. No liner.
