Japan’s long-delayed Chuo Shinkansen maglev project has cleared an important political and environmental hurdle in Shizuoka Prefecture, the section that had kept the Tokyo–Nagoya route from moving ahead in full.
On July 7, 2026, Shizuoka Governor Yasutomo Suzuki told the prefectural assembly that the prefecture would conclude a natural environment conservation agreement with Central Japan Railway Company, better known as JR Central. Shizuoka’s official materials say the agreement is to be signed on July 18, after notification to the national government, JR Central, municipalities in the Oi River basin, Shizuoka City, water-use groups and other parties.
The decision does not mean a new train service is imminent. For travelers planning Japan trips now, the practical route between Tokyo, Nagoya, Kyoto and Osaka remains the Tokaido Shinkansen. No ticketing, timetable or station changes follow immediately from Shizuoka’s decision.
A future route, not a near-term travel option
The Chuo Shinkansen is JR Central’s planned superconducting maglev line between Tokyo’s Shinagawa area and Nagoya, with a later extension toward Osaka. JR Central’s official project information lists the Shinagawa–Nagoya section at 285.6 kilometers, with planned stations at Shinagawa, Kanagawa Prefecture, Yamanashi Prefecture, Nagano Prefecture, Gifu Prefecture and Nagoya.
JR Central says the maglev is designed to run at 500 km/h. Its official project materials describe target fastest journey times of about 40 minutes between Shinagawa and Nagoya, and about 67 minutes between Shinagawa and Osaka once the full route is complete. That would change how visitors move between Japan’s main metropolitan areas, especially for itineraries combining Tokyo, Nagoya, Kansai and central Japan.
Those timings remain future-facing. The original 2027 target for the Shinagawa–Nagoya opening is no longer achievable, and the Shizuoka tunnel section has been the key bottleneck. The Japan Times, the source item for this approved topic, reported that JR Central is looking to begin construction in Shizuoka this year and to complete the Tokyo–Nagoya leg in 2036 at the earliest. That 2036 timing should be treated as a current reported estimate rather than a bookable opening date.
Why Shizuoka had held up the project
The dispute centered on the South Alps tunnel section passing under northern Shizuoka and the upper Oi River area. Shizuoka had raised concerns about water resources, tunnel spring water, excavated soil and biodiversity impacts in the mountain environment.
In the governor’s July 7 explanation, Shizuoka said JR Central had held 22 local briefing sessions from May 26 to June 22 and that understanding among residents and related organizations had progressed, even though some concerns remained. The prefecture also said applications and consultations tied to laws including the River Act and embankment regulation rules had reached the stage needed for the environmental agreement.
The agreement is expected to include continued monitoring during and after construction. Shizuoka’s official explanation says that if unexpected problems occur, work may be temporarily stopped as needed while causes and responses are reviewed. The prefecture also plans a monitoring structure involving local, national and JR Central coordination.
Possible travel impact later
For visitors, the most relevant point is the long-term transport effect rather than the construction decision itself. A completed maglev line would create a second high-speed route between Japan’s largest urban regions and could shorten Tokyo–Nagoya travel dramatically. JR Central also says a shift of some Nozomi passengers to the Chuo Shinkansen could create room for more Hikari and Kodama services on the existing Tokaido Shinkansen, potentially improving access for cities along the current line.
Until opening dates, fares, station access details and operating patterns are confirmed, travelers should continue to plan with the current Tokaido Shinkansen network. The Shizuoka decision is a major project milestone, but it changes future expectations more than present-day itineraries.

Frequently Asked Questions
No. The Chuo Shinkansen is still under construction and is not available to passengers. Travelers between Tokyo, Nagoya, Kyoto and Osaka should continue using the Tokaido Shinkansen or domestic flights.
There is no bookable opening date. The original 2027 target is no longer achievable. The Japan Times reported that the Tokyo–Nagoya section could be completed in 2036 at the earliest if work in Shizuoka starts this year.
Shizuoka’s governor said the prefecture would sign a natural environment conservation agreement with JR Central on July 18, 2026. That agreement is a key step toward allowing main construction work in the Shizuoka section, subject to continuing legal procedures and monitoring.
