Key takeaway

Akishima residents will ask a Tokyo court to stop Nihon GLP's data centres before they are built.

Residents of Akishima in western Tokyo formed a litigation group on 18 October and said on 20 October they will sue Nihon GLP by the end of the year at the Tachikawa branch of the Tokyo District Court⁠¹. They seek a ruling that eight data-centre buildings and three logistics buildings must not be built. Alterna and Nikkei Business report it would be the first suit in Japan seeking an injunction directly against a data-centre operator⁠².

Nihon GLP, the Japanese arm of the logistics developer GLP, plans the campus on about 58.8 hectares of a former golf course north of Akishima Station; the first logistics building began construction in June 2026. In February 2025, 607 residents sought Mediation before a Tokyo metropolitan commission, which ended without agreement on 17 August.

The residents' lawyers plan to argue rights to life and health, to a peaceful and safe life, and to clean water and a natural environment. Nihon GLP said it has not received a complaint and declined to comment. Spain's first data-centre lawsuit, filed in January by a coalition led by Ecologistas en Acción, challenged a regional government's agreement rather than the operator itself.

Deep Analysis

In plain English

Akishima is a city in the western suburbs of Tokyo. A company called Nihon GLP, the Japanese arm of a global property developer, plans to build eight data centres and three warehouses on an old golf course there. Data centres are large buildings full of computers. Local residents worry about the water and electricity they use, the loss of green space and the risk of fire. Residents first tried an official Mediation process run by the Tokyo government, but it ended in August without a deal. Now they plan to go to court and ask a judge to stop the buildings altogether.

Deep Analysis

Root Causes

The site is a former golf course covering about 3.4% of Akishima's 1,734 hectares. Large, flat, already-cleared parcels near Tokyo are scarce, which is why a single conversion can take such a share of a small city.

The project mixes logistics warehouses with data centres. Residents object to features that come with the data-centre half: heavy water use, power demand, and fire risk from batteries and stored heavy oil, which a warehouse campus would not carry.

What could happen next?

Precedent
A ruling for the residents would give Japanese communities a civil-court route against data-centre operators directly.
Consequence
The suit is due to be filed at the Tachikawa branch of the Tokyo District Court by the end of 2026.

Primary parallel: In January 2026 a coalition led by Ecologistas en Acción filed Spain's first data-centre lawsuit at the High Court of Justice of Aragón, against the regional government's agreement with Amazon. Both are first-of-their-kind citizen suits, though the Spanish case targets a government act and the Akishima case targets the company.

Counter-parallel: In Texas the courts worked for the developer. Hill County rescinded its data-centre moratorium on 4 June 2026, seven days after RCM Hill LLC filed a US$100 million federal lawsuit over its 1,235 MW Project Aquila campus.

Consensus view: The residents' lawyers plan to argue personal rights, including life and health, a peaceful and safe life, and clean water and a natural environment, Nikkei Business reported. That aims the case at the operator rather than at a permit, so it does not depend on proving an official broke the rules.

Counter-view: The administrative route has already failed. The Tokyo Metropolitan Pollution Dispute Coordination Commission held six Mediation sessions over about 18 months before closing the case without agreement, and Nihon GLP began its first logistics building in June 2026 regardless. Nihon GLP says it has not received a complaint and declined to comment.

Key tension: Whether a court will treat risks from buildings not yet operating, such as water draw and fire risk from batteries and heavy oil, as concrete enough harm to block construction.
