A sturdy helmet with a sinewy appearance, it features a "shikoro" neck guard and wing—like flaps known as "fukikaeshi." The sharp crescent moon is tilted at an angle so as not to get in the wearer's way when they swing their sword. Part of a traditional armour set known as Tosei—gusoku in Japanese, this armour was favoured by Date Masamune, a feudal lord who ruled over Oshu. It was created by Myochin, a famous armourer from Kamakura in Sagami province (present—day Kanagawa prefecture). Despite losing an eye to illness as a child, Masamune became the head of his clan at a young age; his aggressive territorial expansion earning him the name "The One—Eyed Dragon." Clad entirely in black, his Yukinoshita—style armour was said to have captivated even his enemies.
Upper body armour made from thick iron plates set with vertical joints in the Yukinoshita style. It comes complete with black—lacquered armoured sleeves.
Gauntlets made from thin iron plates layered and fixed together with cord, providing protection down to the back of the hand.
Waist and thigh protection. The "haidate" is made from black cloth, and features tassets along the lower portion.
Greaves made from thin iron plates fashioned into a cylindrical shape that covers the shin and ankle; the heel is protected by "kogake" (foot guards).
