Japanese baseball is really popular over the world because of its exciting fan culture, disciplined players and strong regional pride. The big Nippon Professional Baseball league gets crowds in Tokyo and Osaka but the Route Inn Baseball Challenge League is just as real, passionate and up close. The Gunma Diamond Pegasus team was one of the teams in the BC League when it started in 2008 and they represent the heart of local sports in Gunma Prefecture.

The team helps college players get ready for the NPB draft and gives experienced players a chance to improve their skills. When you watch a Diamond Pegasus game at home you see great athletes trying their best to become professionals, which makes the games very intense.
The Gunma Diamond Pegasus do not play in city stadiums like some other teams. Instead they play in old-style ballparks in Gunma like Takasaki City Jonan Baseball Stadium and Isesaki Stadium. These parks are close to the action so you can hear the bats cracking. The umpires calling out plays. On game days the community comes together to celebrate with food, music and a chance to meet the players after the game. The Gunma Diamond Pegasus games are a lot of fun, with food vendors selling Gunma foods brass bands playing music and fans cheering on the Diamond Pegasus.

Home matches are played across key ballparks in Gunma Prefecture, primarily Takasaki City Jonan Baseball Stadium, Isesaki Stadium (Seven Nuts Stadium), and Ota City Sports Park Baseball Stadium.
Most regular season BC League fixtures utilise unreserved general admission seating across the infield and outfield lawn areas, allowing fans to select their preferred view upon early arrival.
While regular weekday games rarely sell out completely, weekend fixtures, season openers, and promotional giveaway days attract large local crowds, making advance ticket booking recommended.
Jasumo authenticates physical paper tickets and dispatches them via secure domestic courier directly to your hotel concierge or Airbnb location prior to game day.
