NTT East plans 25 Gbps FTTH service in Tokyo

NTT East planned to introduce a 25 Gbps Fiber-to-the-Home (FTTH) service in Tokyo beginning March 2026, a change presented as providing faster residential broadband.

Telecompaper reported the offering would expand on NTT East's existing fiber services and follow recent higher-speed business developments; commercially available FTTH access in Japan remained at 10 Gbps, provided by multiple fiber optic network providers including NTT East/West and Sony-backed NURO Hikari.

The company described the Flet Hikari 25G product as a best-effort FTTH access option that used shared subscriber fiber to connect customers to their chosen Internet Service Providers (ISP) (ISPs). Separate research work in Japan had reached transmission speeds above 1 petabit per second in laboratory settings, and those results were identified as research achievements rather than commercially available services.

NTT positioned the launch within a broader program to develop next-generation digital infrastructure and included work on key devices for an ultrafast optical network under the IOWN project, with NTT Access Service Systems Laboratories cited as a source.

NTT described plans to begin the Flet Hikari 25G service in March 2026 and to pursue device development for the IOWN optical network in 2026.
