Japan’s telecommunications sector is one of the most developed markets in the world.

Japan’s market is served by three multi-service operators offering fixed-line telephony, fixed broadband access, mobile voice telephony, mobile broadband access and pay TV services. Japan’s fixed line market is dominated by incumbent operator NTT.

Fixed line growth in Japan have been stagnant over the past five years. This trend is predicted to continue over the next five years to 2024.

The fixed broadband market is supported largely by two technology platforms: cable TV (CATV) and FttH, with the latter more prominent.

Japan’s mobile market is dominated by three major operators – NTT DoCoMo, KDDI and Softbank Mobile. However, the Japanese government is looking to open its mobile market up to new players for 5G services. Japan’s largest e-commerce company is working on plans to build its own nationwide 4G mobile network with an intended launch by 2020.

Japan has a strong presence as a regional Asian data centre provider and is a global financial and corporate hub and one of the fastest evolving digital markets in the world. Data centre locations have easy access to high-speed international connectivity, with landing points for several submarine cables that connect with the western United States. Japan’s digital economy is highly mature and difficult to serve from overseas or alternative locations. Japan has now evolved into more of an international data centre market driven by the global hyperscale cloud providers expanding in the Tokyo and Osaka markets.

Japan possesses a large and vibrant television industry due to its unique culture and market size. Legislation enacted to restrict ownership has led to a plethora of broadcasters. Japan’s vertically integrated broadcasting industry means broadcasters create as well as distribute content.

NTT DOCOMO has launched a global Internet of Things solution designed to aid customers in the development, of IoT services and has claimed a world first in a 5G test using a 28GHz band antenna on a 5G connected car.

Key Developments:

  • Stagnant growth in the fixed line market is predicted to continue over the next five years to 2024.
  • The Japanese government is looking to open its mobile market up to new players for 5G services.
  • Japan's first Cellular Vehicle-to-Everything (C-V2X) trials are commencing.

Paul, May I congratulate you on a very successful and enjoyable afternoon with the Minister.
