Boat Race Kiryu, Boat racing stadium in Midori, Japan

Boat Race Kiryu is a racing facility in Midori featuring an oval 600-meter track where six boats compete in three-lap races. The venue provides parking and multiple restaurants serving regional dishes for visitors.

Boat Race Kiryu opened on 8 November 1956, the last of Japan's 24 kyōteijō to be built, with Kiryu City as first operator. In September 1997 it became the first Japanese boat racing venue to stage night races, called Aquanight. Facing deficits, closure after fiscal 2003 was considered until the second operator, the Asami Suien racing association, took over all of Kiryu City's race days. The Minami Wing stand opened in April 2005.

The mascot Dorakiryu, a vampire count named for Kiryu, reflects the year-round night racing that began in 2011; goods are sold at the Yamazaki shop in the Dra Shop. Races carry mascot-themed names such as the Dorakiryu Cup, and the New Year meeting is the Gunma Derby.

The course is the Azaumi East Reservoir, a pond built in 1925 east of Azaumi Marsh, so the water is fresh and the surface choppy when the winter-to-spring Akagi-oroshi wind blows. The venue sits at about 130 m elevation, which weakens motor power and makes starts harder. Free shuttle buses run from JR Iwajuku Station in three minutes; Tobu Azaumi Station is a 15-minute walk. Free large car parks stand on both the Dorashop and South Wing sides.

The stadium pioneered nighttime boat races in Japan, using specialized lighting systems for evening events. This innovation lets visitors experience races under floodlights, giving the sport a different character.
