NTT DOCOMO
NTT DOCOMO separated from its parent, Nippon Telegraph and Telephone (NTT), in 1992 and built the dominant mobile network in Japan. The firm operates from the Azabudai Hills Mori JP Tower in Tokyo and maintains data-center assets that anchor its core telecommunications business across Bunkyo-ku, Ibaraki, and Hong Kong. Investment activity flows through NTT DOCOMO Ventures, which targets early- to growth-stage technology companies, and through dedicated vehicles such as the Web3 Infrastructure Investment Fund. The firm has pursued direct strategic positions in decentralized technology — its partnership with Astar Network stands as a public commitment to Web3 infrastructure development. Tokyo 5 Data Center and Osaka 7 Data Center provide the physical backbone for cloud and connectivity services, while the Hong Kong Financial Data Center signals a cross-border infrastructure thesis. The in-house NTT QONOQ Metaverse Unit extends the brand into virtual worlds, and the NTT DOCOMO Design Collection at M+ museum in Hong Kong reflects a wider cultural footprint. NTT DOCOMO Ventures holds membership in the Japan Venture Capital Association, linking it to the domestic early-stage ecosystem. The firm also participates in GSMA, the global mobile-operator trade body, reinforcing its industry-aligned investment posture. In March 2026, the company retired its legacy FOMA and i-mode services, closing a chapter on Japan's early mobile-internet era and freeing capital and talent for next-generation network and venture priorities. Structurally, NTT DOCOMO operates as a publicly listed subsidiary of a former state monopoly, giving it a balance-sheet capacity that pure-play venture firms lack. That hybrid identity — a consumer telco running a disciplined corporate venture arm alongside direct infrastructure holdings — shapes a deal-sourcing funnel that originates inside one of Asia's largest subscriber bases and travels through partnerships with operators like Astar Network.

Frequently asked questions
How does NTT DOCOMO structure its investment activities?
Investing runs primarily through NTT DOCOMO Ventures, its corporate venture arm, which holds membership in the Japan Venture Capital Association. The firm also operates a dedicated Web3 Infrastructure Investment Fund and maintains direct strategic partnerships — such as its collaboration with Astar Network — for blockchain and decentralized-technology exposure. This structure separates venture-stage equity from the company's core telecom balance sheet.
What is NTT DOCOMO's relationship with Astar Network?
Astar Network is a public strategic partner for Web3 infrastructure development. The relationship was disclosed as a business partnership, indicating NTT DOCOMO is anchoring its blockchain and decentralized-application strategy through a dedicated layer-1 protocol rather than through indirect fund investments alone.
Does NTT DOCOMO invest internationally or only in Japan?
The firm maintains assets and investment activity outside Japan. Its Hong Kong Financial Data Center provides infrastructure in a major Asian financial hub, and the NTT DOCOMO Design Collection at the M+ museum in Hong Kong demonstrates a broader cultural and brand presence. The parent group, NTT, operates across Asia, Europe, and North America, and NTT DOCOMO's own description notes a presence in those regions.
What is the NTT QONOQ Metaverse Unit?
NTT QONOQ is an internal metaverse unit based in Tokyo that extends NTT DOCOMO's digital-services strategy into virtual worlds. It operates alongside the company's Web3 fund and Astar Network partnership, forming a three-pronged approach to next-generation internet platforms.
How does NTT DOCOMO's foundation relate to its investment operations?
The NTT DOCOMO Foundation, branded as the Mobile Communication Fund, is a separate philanthropic entity. Available information does not indicate that the foundation participates in venture investing; it appears focused on social-impact initiatives tied to mobile connectivity rather than co-investing alongside the corporate venture arm.
What happened to NTT DOCOMO's FOMA and i-mode services?
The company terminated its FOMA 3G network and i-mode mobile-internet platform at the end of March 2026. The closure marked the end of Japan's first widely adopted mobile-data ecosystem and allowed NTT DOCOMO to concentrate engineering and capital resources on 5G, edge computing, and its venture portfolio.
Is NTT DOCOMO still majority-owned by NTT?
NTT remains the parent company and majority owner of NTT DOCOMO. The subsidiary operates with its own public listing and investment governance, but the capital structure ultimately ties back to the former state monopoly, giving the firm a cost-of-capital advantage relative to independent venture investors.
