Belluna Dome
ベルーナドーム
Saitama Seibu Lions
One of the most unusual stadiums in professional baseball, Belluna Dome is a semi-outdoor domed stadium where home runs can literally fly out of the building — its roof covers the seating areas but leaves the outfield walls open to the outside air.

Belluna Dome has an open structure unlike any other: the dome roof covers the grandstand but the outfield is open, meaning balls can leave the stadium entirely on long home runs.
- ⚾
The park is nestled in the wooded hills of Tokorozawa, Saitama, giving it a forested, almost rustic setting unusual for a professional sports venue.
- ⚾
The Seibu Lions won eight consecutive Pacific League pennants from 1982 to 1992 — one of the greatest dynasties in NPB history.
