Yokohama Stadium is fully open-air with no roof — about 60% of seats have no cover. Bring a poncho (umbrellas banned), arrive 30 minutes early, and check the rain-postponement rule (game starts → no refund even if cancelled mid-play).
Yokohama Stadium is open-air
Unlike Tokyo Dome or PayPay Dome, Yokohama Stadium (home of the DeNA BayStars) has no roof. Rain is a real consideration, especially during the rainy season (June-July) and typhoon season (August-September).
Will the game be cancelled?
Cancellation decisions are typically made 1-2 hours before game time. Light rain usually means the game goes ahead. Check the team's official website or social media for real-time updates. If cancelled, tickets are refunded.
Rain gear essentials
Rain poncho (not umbrella)
Umbrellas are prohibited during games — they block views for people behind you. Bring a clear rain poncho (available at convenience stores for ¥100-300). Clear ponchos let you see the game without obstruction.
Towel and plastic bags
A towel to wipe your seat, and plastic bags to protect your belongings. Simple but essential.
Covered seating areas
Upper infield seats near the backstop have partial roof coverage. If rain is forecast, choose these seats when buying tickets.
Backup plan: Chinatown
If the game is rained out, Yokohama Chinatown is a 5-minute walk away. One of the world's largest Chinatowns with hundreds of restaurants — not a bad consolation prize.
How to buy tickets
BayStars tickets are available through the official site. Remember: if rain cancels the game, you'll get a refund.
