Field of Nine is a Japanese collectible card game published by Konami in October 2000, centered on the Nippon Professional Baseball (NPB) league. The game released in multiple series, with Series 1 and Series 2 confirmed in trading card databases alongside a third series and premium and all-star pack variants. Cards depicted individual Japanese professional baseball players, and parallel versions including Lattice variants added collectible appeal. Field of Nine was produced exclusively for the Japanese domestic market, reflecting Konami's broader strategy in the early 2000s of developing licensed sports card games tied to domestic leagues. The game is now considered a rare collectible, with individual cards appearing on auction platforms.
