Chiba Lotte’s Dome Reconsideration and the Makuhari Turning Point 2 of 3
Key Takeaways:
The city’s insistence on private financing for dome costs effectively positions Makuhari for a dedicated redevelopment fund that brings together domestic institutions, Chiba-based corporates, and global investors.
A 33,000-seat stadium paired with a 20,000-seat arena gives Makuhari the multi-asset scale required for a district model rather than a standalone stadium project.
Rising naming-rights valuations signal that a dome-enabled Makuhari can support investment-grade economics, reinforcing concepts that JSP had articulated long before its formal founding.
Article Summary
Chiba City will review dome and open-air stadium options after the Marines requested a reconsideration and strong fan feedback favored a dome. Starting January 2026, the city will prepare outline designs and compare costs. Past estimates placed an open-air stadium near ¥60 billion and a retractable dome above ¥100 billion. Dome-related costs must be covered by the club and private investors. Naming-rights valuations have risen — including a roughly ¥10 billion, five-year deal for the National Stadium — prompting optimism about revenue recovery. The new 33,000-seat facility will rise in Makuhari New City, where a 20,000-seat basketball arena is also planned.

Private Financing Turns Makuhari Into a District-Scale Opportunity
The article frames the dome review as a technical update, yet its financial terms reshape the entire project. By placing dome-specific costs outside public budgets, the city shifts Makuhari into the realm of commercially disciplined, investor-backed development. A modern dome cannot be financed through conventional club–city arrangements. It requires a structure capable of underwriting multi-decade returns, coordinating district infrastructure, and allocating capital across multiple assets.
This naturally points to a professionally managed redevelopment fund that JSP proposes, blending capital from:
domestic megabanks and national corporations,
Chiba-headquartered companies with territorial commitments,
global investors seeking high-quality Japanese real-asset exposure.
Naming Rights Offer the First Market-Grade Signal
The reference to a roughly ¥10 billion naming-rights deal for the National Stadium is more than a passing comment. It establishes a benchmark for premium venue valuation in Japan and demonstrates that corporate demand has strengthened to global norms. For investors evaluating a Makuhari redevelopment fund, naming rights provide early proof that the project can sustain:
national-tier brand visibility,
multi-asset sponsorship packages,
long-horizon monetization beyond team-specific revenue.
A dome in Makuhari — positioned between two international airports and adjacent to a major convention cluster — is well situated to enter this tier.
Two Venues Give Investors the Scale They Expect
The planned 20,000-seat basketball arena adjacent to the stadium materializes the multi-venue ecosystem needed for private capital to participate at scale. Investors do not underwrite isolated structures. They underwrite systems with diversified revenue and predictable demand.
A paired stadium–arena configuration enables:
dual event calendars that smooth attendance volatility,
cross-venue hospitality and retail patterns,
shared mobility and safety infrastructure,
sponsorship packages that span multiple audiences and demographics.
This is where Makuhari’s evolution mirrors the early thinking captured in the 2017 “Creative City Chiba” concept by JSP Founder, Masa Takeya— an argument that Chiba’s assets should not be treated as isolated pieces but as an interconnected platform. Back then the pillars were healthcare, tourism, and education. Today the stadium and arena, combined with modern infrastructure including AI, become the catalytic software and hardware that allows those same regional assets to converge into a coherent district.
Makuhari’s Geography Aligns With Long-Standing Vision
Long before JSP existed, Masa argued that Chiba should leverage its gateway position, medical institutions, and underutilized waterfront to build a distinctive urban identity. The article’s details now give those ideas a practical chassis. A dome-enabled stadium beside a modern arena provides the activation engine. Makuhari’s geography — between Narita and Haneda, near convention centers, and supported by academic and medical clusters — supplies the strategic canvas.
When these elements are aligned through a fund-based structure, Makuhari becomes more than a stadium project. It becomes the operational expression of a concept first articulated years ago: Chiba can convert its latent strengths into a world-facing district that circulates people, capital, and information.
Our Perspective: A Financial Framework that Unlocks Global-Scale Potential
Japan Stadium Partners reads the article as the moment when a civic redevelopment crosses into investment-grade territory. Private financing requirements, strengthened naming-rights metrics, and multi-venue scale collectively outline the blueprint of a redevelopment fund capable of shaping Makuhari as a next-generation district.
Makuhari is no longer just the site of a new stadium. It is the foundation for a globally connected sports and entertainment ecosystem.
In Part 3, we will show how a unified governance model arranged by JSP can align local, national, and global investors around a long-horizon strategy for Makuhari’s emergence as an international gateway.
