JTOWER Enhances Communication Environment at Toranomon Alcea Tower

In a significant move to improve communication infrastructure, JTOWER Inc., led by CEO Atsushi Tanaka, has implemented state-of-the-art solutions at the Toranomon Alcea Tower, a major mixed-use complex in the Toranomon area of Tokyo. This development is part of the first urban redevelopment project in the Toranomon 2-chome district.

Overview of Toranomon Alcea Tower

The Toranomon Alcea Tower stands as one of the largest complexes in the Toranomon area, covering an impressive floor space of 110,800 square meters in its mid to high-rise sections. This multifaceted facility is designed to support international business activities with office spaces, a business support center, and various commercial facilities. The second-floor deck enhances accessibility to nearby amenities, catering to diverse working styles and business practices.

JTOWER’s innovative indoor infrastructure sharing solution has streamlined communication needs across the entire building by integrating multiple mobile carriers’ equipment into a single system. This transformation not only maximizes space and reduces electricity consumption, but it also significantly lessens the amount of materials and labor needed for construction. Consequently, a more environmentally friendly and efficient network has been established, enhancing customer experience substantially.

Since commencing commercial services for indoor infrastructure sharing solutions in 2014, JTOWER has consistently increased its installations across a wide array of facilities, from commercial centers and office buildings to hospitals, government offices, logistics centers, and exhibition venues. By 2020, the company completed the development of shared equipment compatible with 5G technology, further strengthening its capabilities. As of June 2025, JTOWER boasts an impressive installation count of 710 indoor infrastructure sharing projects across Japan, solidifying its status as a leader in the industry.

What is Infrastructure Sharing?

Infrastructure sharing enables mobile carriers to consolidate their network systems, which significantly reduces costs associated with equipment, operations, and maintenance. This approach leads to a more efficient network configuration, while also minimizing environmental impact, thanks to lower energy consumption and reduced material requirements.

Overview of Indoor Infrastructure Sharing Solutions

For large buildings exceeding 10,000 square meters, the need for robust indoor mobile signal infrastructure is paramount. By employing infrastructure sharing, property developers benefit from streamlined operations, decreased energy expenses, and consolidated communication channels—all while mobile carriers enjoy reduced capital investments and operational costs. Moreover, this initiative significantly enhances user satisfaction through improved connectivity.

Some examples of JTOWER's implemented facilities include:

- Office Buildings: Otemachi One, Shibuya Sakura Stage, Azabu-dai Hills Mori JP Tower
