Overview
- JR Central held a public trial on Tuesday, September 29, 2026, carrying about 144 participants on the 42.8 km Yamanashi line and reaching a top speed of 500 km/h.
- Company officials said the test line is technically complete and pointed to more than 5.6 million kilometres of prior safety runs as evidence the system can operate in service.
- Riders and reporters described the onboard design in detail, noting a low ceiling, small windows, fixed 15° seats with no recline, limited overhead luggage space and projector displays for speed and route.
- The planned Shinagawa–Nagoya commercial segment has seen costs roughly double to about ¥11 trillion and is now expected to open in 2036 or later because of environmental measures and permitting for the Shizuoka section.
- Analysts warn that Japan’s falling population and doubts about future ridership, together with Oigawa river water and ecosystem concerns, could raise long-term financial and permitting risks for the full project.
