Japan is pushing the boundaries of home internet technology, offering individual users data transfer speeds of up to 25 Gbps per second. NTT East, a leader in telecommunications in the country, is launching its new service, “Flet’s Hikari 25G,” covering select areas across Tokyo by the end of March 2026.

Japan’s internet speed is making headlines.

This service, delivered over fiber-to-the-home (FTTH) infrastructure, more than doubles the current maximum speed of 10 Gbps available in the country. Even when technical losses and network traffic are factored in, users are expected to achieve speeds of up to 22.5 Gbps per second.

This massive capacity increase is driven by the rapidly rising demand for data in the digital world. Streaming services with 4K and 8K resolution, latency-sensitive online gaming, and cloud computing services requiring large file transfers are placing a heavy burden on existing infrastructure.

NTT East, as part of its next-generation digital infrastructure strategy, aims to manage high network traffic in the most efficient way possible. The company is also working on more advanced technologies under its IOWN (Innovative Optical and Wireless Networking) project, focusing on the development of ultra-fast optical communication devices for the post-2026 era.

The cost of the fastest home internet package in history has also been revealed. The monthly subscription fee for the plan, which will go on sale on March 31, 2026, is set at 27,500 Japanese yen, including taxes. This figure is approximately $175 at current exchange rates. However, 25 Gbps is not the final destination for the Japanese technology giant.

NTT East announced that, anticipating future data needs, it has already begun technical preparations for a 50 Gbps home internet service. This development reinforces Japan’s leadership in the global broadband market and opens the door to an era that eliminates hardware limitations for end-users.
