Auxiliary armours of Japan

Auxiliary Japanese armours are optional armour items worn by the samurai class of feudal Japan in addition to the traditional six armour components.

Description
The six major articles or components of Japanese armour (hei-no-rokugu, roku gu, or roku gusoku) are the dou or dō (chest armour), kabuto (helmet), mengu (facial armour), kote (armoured sleeves), sune-ate (shin armour), and the hai-date (thigh armour). Additional armour protection was available for the neck, armpit, chest, waist and feet. These auxiliary armours covered areas of the body that were exposed by gaps in the regular armour items or were additional protection was required.

Wakibiki
Wakibiki are simple rectangles of cloth covered with kusari (chain armor), karuta (small rectangular or square plates), or kikko (hexagon plates), these iron or leather armors or a combination of them were sewn to the cloth backing. Wakibiki could also be made from one solid piece of iron or hardened leather. The wakibiki had cords connected to them which allowed the wakibiki to hang from the shoulder, the wakibiki was then suspended over the exposed arm pit area. Wakibiki were worn inside the of the chest armour dou (dō) or on the outside depending on the type.

Manju no wa
Manju no wa, ( also manjunowa or manju nowa ) are a combination of shoulder pads, collar and armpit guards in one that protected the upper chest area. Manju no wa were covered with different types of armour including kusari (chain armour), karuta (small square or rectangular armor plates), or kikko (hexagon plates), these iron or leather armors or a combination of them were sewn to a cloth backing. The armour could be exposed or hidden between a layer of cloth. When worn the manju no wa looked like a small tight fitting vest. Manju no wa have small wings that would pass under the arm pit area from the back and attach to the front of the manju no wa with a button, toggle or ties.
