Wa shogi

Wa shogi (和将棋, wa shōgi, harmony chess) is a large board variant of shogi (Japanese chess) in which all of the pieces are named for animals. It is played either with or without drops. Because of the terse and often incomplete wording of the historical sources for the large shogi variants, except for chu shogi and to a lesser extent dai shogi (which were at some points of time the most prestigious forms of shogi being played), the historical rules of wa shogi are not clear. Different sources differ significantly in the moves attributed to the pieces.
