Regarding the construction of the Linear Chuo Shinkansen, last year, a meeting of experts from the Ministry of Land, Infrastructure, Transport and Tourism compiled an interim report stating that the adverse effects on water resources that Shizuoka Prefecture is concerned about could be suppressed by taking sufficient measures. , Shizuoka Prefecture's expert group has expressed opinions such as concerns about the report.
On the 30th, a meeting of experts from the Ministry of Land, Infrastructure, Transport and Tourism responded to these opinions.
In this, the Shizuoka side pointed out that there is no concrete measure for "returning the total amount" to return all the water that has flowed into the tunnel, including during excavation, while the national side pointed out that "JR Central is the area. You should make a decision by communicating with other people. "
In response to the opinion that the Shizuoka prefecture side did not show the monitoring procedure to confirm whether the construction was proceeding properly, the national side said, "JR Central decided on the monitoring plan including the concrete procedure. We are aware that we will continue to do so, "he reiterated his conventional view.
