Meeting of experts “Spring water for construction work can be maintained by returning to the Oi River”
JR Tokai is aiming to open the "Linear Chuo Shinkansen", which is said to connect Tokyo Shinagawa and Nagoya in as little as 40 minutes, in 2027, but in Shizuoka Prefecture, the amount of water in the Oi River that supports the lives of residents through underground tunnel construction. We do not allow the start of construction in the prefecture because there is a concern that there will be adverse effects such as a decrease in the number of tunnels.
Under these circumstances, the Ministry of Land, Infrastructure, Transport and Tourism set up a meeting of experts in the form of arbitration last April, and summarized the results of the discussion in the "interim report" at the meeting on the 19th.
According to this, regarding the impact of tunnel construction on the Oi River, if a path for the groundwater that springs up in the tunnel is created and all the amount is returned to the Oi River, the amount of water in the middle and downstream areas will be maintained.
After that, he requested JR Central to take a polite response, saying that it should be possible to communicate sufficiently with the residents of Shizuoka Prefecture and the basin so that their anxieties and concerns can be dispelled.
The interim report was finalized one year and eight months after the establishment of the Council of Experts, but Shizuoka Prefecture has said that it will hold further discussions with the JR side, and there is still no prospect of starting construction in the prefecture.

Linear Chuo Shinkansen What is the problem between Shizuoka Prefecture and JR Central?
The Linear Chuo Shinkansen travels at 500 km / h and is considered to be the next-generation transportation aorta that connects Tokyo / Shinagawa and Nagoya in as little as 40 minutes.
In October 2014, JR Tokai started construction after the Minister of Land, Infrastructure, Transport and Tourism approved the construction implementation plan for this section.
The construction cost is expected to be about 7 trillion yen, and we are aiming to open in 2027.
However, due to difficulties in discussions between the prefecture with the authority to permit and JR Central over the construction work in Shizuoka Prefecture, it is difficult to open the business as planned.
The Shizuoka Prefecture side has pointed out that the tunnel construction under the local Oi River may reduce the water in the river and adversely affect the water resources and ecosystem of the basin.
The Ministry of Land, Infrastructure, Transport and Tourism has set out to make adjustments as it is necessary to achieve both the realization of early linear opening and avoidance of impacts on water resources, etc. Was installed.
Then, deepen scientific and engineering discussions focusing on measures to prevent the decrease in river water volume and the impact on groundwater in the middle and downstream basins, and if sufficient measures are taken on the 19th, the impact will be suppressed. We have compiled an interim report such as.
However, Shizuoka Prefecture plans to hold further discussions with the JR side.
In the future, the prefecture's own "specialized subcommittee" will discuss the impact of tunnel construction on the upper reaches of the Oi River, and there is still no prospect of starting construction in the prefecture.
