Fighters Kamagaya Stadium is a stadium located in Kamagaya, Chiba Prefecture, Japan, and is primarily used for baseball.

It is home to the Kamagaya Fighters, the Eastern League farm squad of the Hokkaido Nippon-Ham Fighters of the NPB.

Fighters Kamagaya Stadium opened in March 1997 as a replacement for the Fighters farm stadium located near the Tama River.

Also, the stadium was near a bridge on the Tokyu Toyoko Line, so games had to be interrupted when a train passed by.

The stadium construction only had a few issues, primarily with opposition with residents of Kawasaki.
