This helmet was owned by Tachibana Akinao, the 7th lord of the Yanagawa domain. It is one of his collection of Kawari Kabuto, the so-called “unusual helmets”. It seems that Akinao, who was eager to compile the history books of the Tachibana family, had collected arms and armours related to his ancestors.
The design of this helmet shows the dynamism of warrior culture that is the characteristic of Kawari Kabuto seen in the early Edo period (17th century). It is embellished by a wooden structure in the shape of the Kanji character of ‘Dai’ (means great)’ on the top and a silver skull on the front of the Zunari (head-shaped) helmet, which are both bold and splendid designs. The character ‘Dai’ was favored by warriors since its shape, which spreads out wide toward the end, signifies being increasingly successful. ‘Dai’ is also a part of the name of the person who presented this helmet to Lord Akinao.
