In shogi, the Pinwheel (風軠kazaguruma) is an uncommon opening with the rook on the bottom rank 9 enabling it to switch between a Ranging Rook and Static Rook attack.
The pinwheel name comes from the way the king is able to rotate around the gold positioned on the 58 square as if it were a wheel.
Example of development from Habu (1992).

A similar position occurs in a 1991 game between Yasuharu à Âyama (Black) and Michio Ariyoshi (White).
