A white hood made from silk, it covers the entire head except for the eyes, meaning that while it hides the wearer's expression, it does not affect their vision. The Otani family crest of two facing butterflies ("mukaicho") is depicted on the back. Yoshitsugu favoured it over his usual helmet when he was struck by illness. This Tosei—gusoku armour was worn by Otani Yoshitsugu, the famous ally of Ishida Mitsunari and senior vassal of the Toyotomi clan. Yoshitsugu was given the role of the Deputy Minister of Justice, earning him the title Deputy Otani. At the Battle of Shizugatake and during the attack on Kishu, Yoshitsugu aided in Hideyoshi's attempts to unite the country, gaining him his lord's confidence and earning him a place on the battlefield at Kyushu, Odawara, Oshu, and other locations.
Upper body armour coated with black lacquer, it was later modified into a double—plated design that incorporated clasps and was decorated with gold. The minimal sleeve armour is designed to reduce the overall weight.
Gauntlets made by layering scale—like curved plates. They feature sharpened fingertips and black—lacquered iron, hemmed with a golden colour.
Waist and thigh protection made by layering thinly cut hemp over traditional pants. Though not offering a lot of protection, their lightness allows for ease of movement. Their effectiveness as protective wear can be increased, for example, by utilising a thick belt.
Greaves made by joining together scale—like curved plates and fixing them with cord. Unlike their corresponding upper body armour, they have a thin, rustic—coloured coating which protects them from wear and tear.
