This actually exists
Tower 11, a hotel tower connected to ES CON Field HOKKAIDO, has an observation hot spring bath that overlooks the baseball field. Nowhere else on Earth can you soak in a hot spring while a professional baseball game plays out below you.
What you actually see
The hot spring is in the upper floors of Tower 11, behind center field. You can see the field, the outfield, and the scoreboard. You cannot read the scoreboard text or see individual player faces. It's a panoramic view of the game from a distance, not a front-row seat. Think of it as ambient baseball while bathing — check scores on your phone for details.
How to access it
Day-use bathing
Available on game days and non-game days. About ¥2,000-3,000 for day use. Game-day pricing may be higher. Book in advance through the Tower 11 website.
Hotel stay
Staying at Tower 11 includes bath access. Rooms start around ¥15,000-25,000 per night. Game-day rooms are more expensive and sell out fast.
The ideal ES CON Field day
Arrive at F Village by noon. Browse the 30+ restaurants and farmer's market. Watch the game from the stands (14:00 or 18:00 first pitch). After the game, head to Tower 11 for an onsen soak. If staying overnight, wake up and explore Hokkaido the next day.
How to buy game tickets
The Fighters are a Klook partner team. English-language purchasing with international cards available. Book the Tower 11 onsen or hotel separately through their official site.
