ES CON Field Opens
Opened in March 2023 in Kitahiroshima, Hokkaido, ES CON Field cost approximately 60 billion yen, NPB's largest stadium project. It became the first NPB home stadium to combine natural grass with a retractable roof, prioritizing player health over the traditional artificial turf dome model.
Ballpark Village Concept
The stadium anchors 'Hokkaido Ballpark F Village,' a mixed-use development with hotels, hot springs, restaurants, shopping, camping, and farms designed to attract visitors on non-game days. Modeled on MLB ballpark developments, annual visitors exceed 3 million, transforming Kitahiroshima's economy.

Business Innovation
The stadium features craft breweries, sushi counters, BBQ terraces, and diverse seating from sofas to private suites. Naming rights generate approximately 500 million yen annually. The stadium-as-revenue-generator model presents a new paradigm for NPB team economics.
Impact on NPB
ES CON Field's success influences projects like the Yomiuri's planned Tsukiji stadium. However, the 60-billion-yen price tag risks widening facility gaps between wealthy and budget teams. The stadium marks NPB's transition from 'places to watch games' to 'places to experience entertainment.'
Technical Challenges of Natural Grass Maintenance
Maintaining natural grass through Hokkaido's harsh winters was the stadium's foremost technical challenge even before opening. A subterranean hot-water piping system prevents root freezing during winter, while artificial photosynthesis-promoting lights compensate for reduced sunlight when the retractable roof is closed. The turf blend of Kentucky Bluegrass and Perennial Ryegrass was selected after years of trial cultivation. Groundskeepers carry out resodding and repairs year-round, performing intensive maintenance between games during the season. Though upkeep costs far exceed those of artificial turf stadiums, the reduction in player injuries justified the investment.
Ripple Effects on the Regional Economy and Transport Infrastructure
The opening of ES CON Field reshaped Kitahiroshima's economic landscape. Restaurants and lodging facilities have emerged around the stadium, and commercial land prices have trended upward. Transportation, however, remains a challenge. The nearest station, Kitahiroshima Station, is roughly a 20-minute walk, and post-game crowding from concentrated spectators is a persistent issue. Hokkaido Railway Company has been studying a new station adjacent to the stadium, with construction plans underway. Parking accommodates around 6,000 vehicles, but full-capacity events cause road congestion, prompting expanded shuttle-bus services and cycling incentives. The project has drawn national attention as a model for sports-facility-led urban development in regional cities.
Design Philosophy That Changed the Distance Between Players and Fans
A defining feature of the stadium's design is the minimized distance between seats and the playing field. The front row sits roughly five meters from the foul line, drastically closer than conventional Japanese stadiums. Bullpens are visible from the stands, allowing fans to watch warm-up pitches up close. A terrace section along the third-base side is at field level, close enough for eye contact with fielders. While this proximity creates immersion, it also increases foul-ball risk, addressed through carefully placed netting. Ground-level dining areas let fans enjoy a meal while watching from close range. The design creates attendance motivations that screen-based viewing cannot replicate.
