Tanase Shogi (棚瀬将棋) is one of the important bridge engines in computer-shogi history. It came from the same development lineage as Tōdai Shogi, but it represented a rebuild by programmer Yasushi Tanase (棚瀬寧). In the late 2000s, it was strong enough to sit near the top of major computer-shogi events and became a familiar benchmark in conversations about practical, tournament-ready engine strength.
