Saginomiya joseki
In shogi, the Saginomiya joseki is a joseki for a Left Silver-5g Rapid Attack vs Fourth File Rook opening. It was originally conceived by Teruichi Aono between 1975 and 1985, and further popularized in title matches by Kunio Yonenaga. The name Saginomiya comes from the fact that both Aono and Yonenaga lived in the Saginomiya District of Nakano in Tokyo.
