This kabuto features a black-lacquered iron bowl of fifty-eight plates in the suji-bachi style, signed by Myochin Nobuie and dated Tenbun 2 (1533), placing its origin in the Muromachi period. The bowl is distinguished by four arrow-like shinodare ridges, a configuration known as yon-houjiro.

The shikoro (neck guard), hachimanza, houjiro metalwork, kuwagata, and maedate are late Edo period (19th century) additions, reflecting a revivalist aesthetic. The shikoro is iron, black lacquered in kiritsuke kozane style with blue lacing and a silver lacquer circle at the rear, finished with white mongara odoshi. The fukigaeshi display the Odamokkou crest, while the kuwagatadai is openwork chrysanthemum, and the maedate is a gold-lacquered wooden dragon.

This helmet exemplifies the enduring prestige of the Myochin school, combining a robust 16th-century bowl with ornate 19th-century mountings. The master, Myochin Nobuie, is considered one of the most important armor makers in Japan and founder of the Myochin School It is accompanied by a certificate from Kozu Yoshiyuki, a noted authority on Japanese arms and armor.
