The pilot project, set to commence in June 2026, involves installing a modular, small-scale data center under an elevated section of the Oimachi Line. This places servers directly within an environment defined by constant vibration, fluctuating temperatures, and sustained noise from passing trains. The demonstration experiment is designed to evaluate whether compact infrastructure can function under these conditions without compromising operational stability. The participating companies include Tokyu Corporation, Tokyu Railways, Its Communications, and Tokyu Construction, each contributing to site provision, connectivity, and system design. Measurements will focus on sound insulation, thermal insulation, vibration isolation, and cooling efficiency within the confined structure beneath the tracks. Such experiments are triggered by the increasing pressure on urban infrastructure as demand for low-latency data processing continues to grow. The expansion of generative AI tools , IoT systems, and 5G networks has intensified the need for distributed computing facilities located closer to users. In dense cities such as Tokyo, conventional large-scale data centers face limitations related to land availability and power access, creating interest in smaller, modular deployments. Medium-sized facilities are now expanding at a 12% compound annual growth rate through 2031, as they can be deployed more quickly within dense urban environments. The modular system used in this trial integrates servers, cooling equipment, and power supply into a compact enclosure, allowing deployment without constructing full-scale buildings. This approach is intended to reduce installation complexity and enable faster deployment in constrained environments where traditional facilities are difficult to build. One advantage of this proposed setup is its use of pre-existing infrastructures - as the use of existing railway corridors introduces a potential pathway for expanding digital capacity without new land acquisition. This is very important because land constraint is becoming increasingly difficult to ignore in Tokyo, where property prices rose by 69% in 2024, according to Mordor Intelligence. The city already hosts 132 operational data centers, with at least 18 more currently under construction, adding further pressure on available space. The project setup also has access to pre-existing fiber optic networks installed along the Tokyu rail lines. These high-capacity connections could allow under-track data centers to integrate directly into established communication backbones, reducing the need for additional network construction. The consortium is considering broader deployment along the Tokyu Line network, including areas such as Shibuya, where demand for data processing capacity remains high. However, the technical feasibility of operating servers in such environments remains uncertain. The result of this test will determine whether the model can be extended across other sections of the Tokyu rail network.
