Matsumoto Baseball Stadium, Baseball stadium in Matsumoto, Japan

Matsumoto Baseball Stadium is a baseball ground in Matsumoto, Nagano Prefecture, with natural grass in the outfield, a clay infield and a foul area of sand-filled artificial turf. Its two-tiered grandstand seats 25,000 and has a roof behind home plate; six floodlight towers light evening games. The outfield is a grass seating area.

The stadium's origins lie in a 1924 proposal by the prefectural governor to mark the 25th wedding anniversary of Emperor Taisho and Empress Teimei; the baseball ground was built near Asama Onsen and opened on 21 September 1926 as Nagano Prefecture Matsumoto Baseball Field. It was rebuilt and reopened in 1991 after the prefecture transferred it to the city in 1989, and floodlights were added later.

The stadium regularly hosts school tournaments that draw families and supporters from across Nagano Prefecture. On match days, the stands fill with students and parents in a way that feels more like a neighborhood gathering than a sporting event.

The stadium is in Matsumoto, Nagano Prefecture. From the east exit of JR Matsumoto Station, take the Alpico Kotsu "Yokota Shindai Junkan" bus from stop 2 and get off at Matsumoto Daiichi High School, about five minutes on foot; a taxi takes about ten minutes. Extra buses run from the station on days with professional games.

The 13 triples in the 1947 doubleheader were aided by the old prefectural field's low rope-and-net fence and a special ground rule: a ball that bounced over the fence counted as an entitled triple. In the first game alone, the Giants hit four triples in one inning; the second game ended 18-13.
