The president of JR Tokai has made a comment that it is unlikely that Linear Chuo Shinkansen (Maglev Shinkansen) will start the service in 2027. JR Tokai is planning Linear Shuo Shinkansen between Shinagawa and Nagoya, where more than 80% will be an underground tunnel.
Shizuoka prefecture has a concern with the tunnel JR Tokai is planning to dig for Linear Chuo Shinkansen. An initial environmental impact study showed that there will be 2 tons of underground water spewing out from the tunnel every second. Shizuoka prefecture argues that part of the underground water will come from the Ooi River and the tunnel for Linear Chuo Shinkansen will have a large impact on the water level of the Ooi River. JR Tokai has shown other studies indicating underground water will come from all over the place and the Ooi River is a very small portion of the source of underground water and the tunnel will have a very minimal impact on the Ooi River. But Shizuoka prefecture is taking none of that. Currently, the construction of the tunnel for the Linear Chuo Shinkansen in the Shizuoka area is standstill.
Currently, four stations are planned between Shinagawa and Nagoya for Linear Chuo Shinkansen:
Hashimoto, Kanagawa
Koufu, Yamanashi (southern part of the city)
Kamisato IInuma, Nagano (Iida city)
Mino Sakamoto, Gifu (current Chuo Line station)
