Project Timeline and Capacity

The first phase of the 36MW data center campus is scheduled to become operational next year, sources indicate, initially offering 18MW of capacity. The remaining 18MW is expected to come online in 2027, according to the company’s development timeline. This staggered approach reportedly allows Stack to meet immediate demand while planning for future expansion needs in one of Japan‘s key technology hubs.

Financing Structure and Partners

The debt financing package was fully underwritten by Natixis CIB and Societe Generale, with both institutions also serving as green loan coordinators, according to the financing announcement. Multiple leading Japanese and international lenders contributed to the funding, though specific institutions were not named in the initial reports.

Strategic Importance for Asian Expansion

Preet Gona, Stack’s CEO for the APAC region, stated that “this transaction underscores Stack’s ability to align with long-term capital partners and deliver sustainable, scalable capacity in Japan.” Company representatives suggested that as demand for mission-critical digital infrastructure accelerates across the region, this financing ensures Stack can expand with “scale, speed, and certainty.”

Sustainability Focus

The green financing structure reportedly enhances Stack’s “ability to expand efficiently while embedding sustainability across its development platform,” according to company statements. While specific sustainable features of the Tokyo facility have not been disclosed, analysts suggest that green financing typically requires meeting specific environmental standards and performance metrics.

Company Background and Regional Presence

Stack Infrastructure was launched in early 2019 by investment firm IPI Partners following the merger of former Infomart and T5 assets. The company announced its expansion into the APAC region in October 2021 and has been rapidly building its presence since. In addition to the Tokyo campus, Stack is reportedly developing an Osaka campus in partnership with ESR and maintains data centers in operation and development in Australia and Seoul, South Korea.

Market Context

Industry analysts suggest that this significant investment reflects growing confidence in Japan’s digital infrastructure market and increasing demand for sustainable data center solutions. The location in Inzai places the facility within one of Tokyo’s key data center clusters, positioning Stack to serve both domestic and international clients requiring high-capacity computing resources in the Asian market.
