JTOWER Expands Indoor Infrastructure Sharing Solutions Across Japan

As of June 2026, JTOWER, a leading provider of indoor infrastructure sharing solutions, has successfully deployed its services in 874 locations across Japan. This significant milestone represents a remarkable 123% increase compared to the previous year, showcasing the company's commitment to enhancing mobile communication infrastructure.

The increasing demand for robust mobile connectivity has led JTOWER to broaden its reach, particularly between April and June 2026. Notable installations include large composite facilities like 'Quartz Shinsaibashi' in Osaka, alongside various office buildings, commercial centers, hotels, governmental institutions, and hospitals. A key trend observed in this period is the replacement of existing 4G communications equipment with shared infrastructure, which has led to a significant rise in new deployments.

Since 2014, when JTOWER launched its commercial indoor infrastructure sharing services, the company has steadily increased the number of installations. By 2020, JTOWER had developed and implemented shared devices compatible with 5G technology, further strengthening its service capabilities. As JTOWER prepares for continued growth in the latter half of the 2026 fiscal year, the focus on indoor infrastructure sharing is expected to become increasingly mainstream. This shift is primarily driven by mobile carriers' intention to upgrade their equipment, which facilitates an effective transition to shared infrastructure.

Understanding Infrastructure Sharing

Infrastructure sharing allows mobile carriers to consolidate their network equipment, which has historically been managed independently. By pooling resources, carriers can achieve significant savings in operational costs, maintenance, and overall infrastructure development. This not only enhances the efficiency of network construction but also contributes to reducing environmental impact through lowered power consumption and material usage.

Benefits of Indoor Infrastructure Sharing Solutions

For large buildings exceeding 10,000㎡ in floor area, improving indoor mobile signal quality has become increasingly vital. Indoor infrastructure sharing offers numerous advantages for real estate developers, such as saving space, decreasing electricity costs, and simplifying operational management. Mobile carriers benefit from reduced capital expenditures and operational expenses while end-users enjoy improved signal quality and overall satisfaction.

Examples of facilities benefiting from JTOWER's solutions include:
Complex Facilities: Shibuya Sakura Stage, Azabudai Hills, TOFROM YAESU THE FRONT, OIMACHI TRACKS.
Commercial Facilities: Aeon Group stores, MIYASHITA PARK, Mitsui Shopping Park LaLaport locations.
