The forecrest on this armour is a game piece from shogi, a board game of strategy native to Japan. The kyosha piece, (literally "incense chariot") is sometimes refered to as the "lance". During a game kyosha is allowed to move forward an umlimited number of spaces on the board. It is not, however, allowed to move backward. For this reason, kyosha was thought to embody the ideal warrior spirit of unrelenting advance with no retreat. This forecrest is made in the form of a box that may have been used to hold charms or invocations to deities.
