Building area approx. 50,000㎡ and capacity approx. 35,000. ES CON FIELD HOKKAIDO is a new stadium with an audience area of up to 6 floors above ground, starting from the field level dug below grade on the 2nd basement floor. Prioritizing harmony with the surrounding environment, the design blends into the area, such as building a terrace and roof garden in the middle of the building. We desire the visitors to ES CON FIELD to become attached to the place.

The new stadium with attention to detail is Japan's first openable covered natural turf stadium. The south side has a glass wall to encourage the growth of turf. The spectators will also be healed by seeing the fresh scent of grass and the colorful greens. It is a stadium that aims to be both player-first and fan-first, where you can feel comfortable with all five senses.

“Creating a ballpark the world has never seen before.”
Designing a ballpark no one has ever seen before. This is a series of difficulties. I have asked myself many times why this is so difficult. To "create something the world has never seen before", not something that already exists.
The design team consists of architecture, structure, mechanical and electrical equipment designers, and experts in the field of landscape, interior, quality, administration, geology, earthquakes, groundwater, wind, snow, turf, evacuation, information, security.
We have welcomed many experts to the team and have already overcome many difficulties together. Still, the challenge continues. We design with free ideas that are not bound by traditions and styles of established ballparks. Everyone on the design team wants to create an exciting place where they would want to invite their own family and friends. We take on difficulties together with everyone involved in the project.
In spring in 2023, "Es Con Field Hokkaido" will be completed but the completion is not the end. It will continue to evolve. We have intentionally made room for evolution. Let's create a "ballpark that the world has never seen before" together with everyone.


The vision of ES CON FIELD was to bring some of the intimacy and tradition of American baseball to Hokkaido but reimagine it in a uniquely Japanese experience. Inspired by the rural architecture throughout the island and by the local materials, colors and textures, the ballpark is deeply rooted to the culture and history of the region. The transparency and views through the concourses pulls in nature from the existing forest and landscape and weaves it into the seating bowl. Fans will enjoy some of the closest seats to the action in Japanese ballparks while having the comfort that an operable roof brings during the cold beginning and end of the season. When the words “PLAY BALL” finally echo in the ballpark on opening day, a new era of baseball will reign in Japan.
