Maglev Tunnel as an election campaign theme

Post by Miss Maglev »

The election for Shizuoka Prefecture's governor, which will be held in June 2021, is expected to be a head-to-head contest.
 Supporters of newcomer Shigeki Iwai (former vice minister of Land, Infrastructure, Transport and Tourism) harshly criticized the current prefectural administration of incumbent Govenor Heita Kawakatsu, saying, "The Governor talks about a lot of problems, but there are no results to show what he has done".

 On the other hand, Govenor Kawakatsu described the MLIT (Ministry of Land, Infrastructure, Transport and Tourism) and the Central Japan Railway Company (JR Tokai) as "powerful forces" in a video message he sent to the opening of his office in Shizuoka City on March 16. Speaking about himself on the campaign trail, he said, "I feel like a weak person standing up to a giant. Once the water is lost, it will not come back. We have to resist," he said.

 Govenor Kawakatsu, who has criticized JR and the national government's handling of the water problem in the Linear-Maglev project, has previously ridiculed Mr. Iwai, then vice minister of MLIT, as now being "the face of the national government" (because of Mr. Iwai's support for the Linear-Maglev project), and seems to be positioning the gubernatorial election as a " substitute war" against the proponents.

Maglev Tunnel as an election campaign theme

Post by Miss Maglev »

In an interview on May 18, JR Tokai president made no mention of the Shizuoka gubernatorial election, instead saying that 'eliminating residents' concerns is the most important thing' for linear maglev construction.

Shin Kaneko, President of JR Tokai, stressed the need to continue to explain the ongoing conflict with the prefecture over the outflow of spring water from the tunnel construction. "The most important issue in the water problem is to resolve the concerns of the people in the middle and lower reaches of the Oi River about the use of water".

 Last week, a citizens' group submitted about 20,000 signatures to the prefectural government regarding the construction of the linear line Shinkansen. The prefectural government has informed the JR Tokai about this.

Accessed 2021-05-20


As for the linear railway, current Governor Kawakatsu has not approved the start of construction of the Shizuoka section, citing concerns about the decline in the volume of water in the Oi River and the impact on the natural environment of the Southern Alps.

Governor Kawakatsu pointed out that, Mr. Iwai, his competitor in the upcoming election, was the "face of the Ministry of Land, Infrastructure, Transport and Tourism" because he was the Vice Minister of Land, Infrastructure, Transport and Tourism, and that he was composed of "conflicting opinions on the side of advancing the linear railway and the side of stopping it.

Mr. Iwai said that the construction of the Linear maglev should not begin without the understanding and cooperation of the residents of the Shizuoka basin. He emphasized that the understanding of the watershed area is a prerequisite.

Governor Kawakatsu pointed out that "the most important difference" is how to return all the spring water generated by the tunnel construction, including that flowing out of the prefecture, and rejected JR Tokai's proposal to return all the spring water in Yamanashi Prefecture over a period of up to 20 years, saying, "I have concerns about whether we can protect the water and organisms in the basin.

Mr. Iwai recognized that the "gap with the prefecture has not been bridged even at the (MLIT's) expert meeting" regarding the return of all the water. It is important to base the decision on scientific evidence. It is important to base the decision on scientific evidence, and we need to think about it without bias," he said, without stating the necessity of returning the entire amount.

Shizuoka disapproval of the draft interim report

Post by Miss Maglev »

 Shizuoka Prefecture has expressed its disapproval of the draft interim report of the Ministry of Land, Infrastructure, Transport and Tourism's expert panel to review JR Tokai's environmental measures for the Shizuoka section of the Central Linear Shinkansen, making the future of the discussion uncertain. Governor Heita Kawakatsu has gone so far as to call for the replacement of the chairperson of the panel, claiming that the panel is not neutral and approves of JR Tokai's plans.

Shizuoka gubernatorial election open debate: Kawakatsu: Linear railroad issue heated up; Iwai: Residents may decide to change route

Translated info and summary of a Japanese report

https://www.at-s.com/news/article/shizuoka/906481.html Accessed on 2021-05-26

On June 25, incumbent Heita Kawakatsu (72) and former councilor Shigeki Iwai (52), both of whom have announced their candidacy in the upcoming gubernatorial election [...] attended an open debate hosted by the Shizuoka Junior Chamber of Commerce and Industry at Shimizu Terrsa in Shimizu Ward, Shizuoka City. When Mr. Iwai took a tough stance against JR Tokai, saying that "changing the route or stopping the construction is an option", Mr. Kawakatsu responded with "a very important comment", and a heated discussion ensued.
[...]

They asked each other questions on the issue of the linear Maglev. Kawakatsu asked Mr. Iwai whether he agreed or disagreed with the draft of the interim report compiled by the expert committee of the Ministry of Land, Infrastructure, Transport and Tourism, which states that after the tunnel is dug, spring water from Yamanashi Prefecture will be pumped up for about 20 years. Mr. Iwai emphasized his strict stance, saying, "We will not approve the project unless the residents of the basin understand it. Mr. Kawakatsu responded by saying that it was only natural to obtain the understanding of the local residents and asked again whether he agreed or disagreed with the draft report, but time ran out.
 Mr. Iwai's reference to changing the route and stopping construction was also in response to Mr. Kawakatsu's question, and Mr. Iwai responded, "If the local residents make a decision, I will convey that decision. If the local residents make a decision, I will convey it to them." When Mr. Kawakatsu asked whether Mr. Iwai was speaking from the responsibility of the LDP as a whole, Mr. Iwai said, "That may happen based on the situation at the time".

Summary of a Japanese Media report
We have been asking JR Tokai to return all the spring water from the tunnel, but they have not responded in good faith. It is difficult to cooperate with JR Tokai at this time.

In October 2009, Governor Heita Kawakatsu, who had just won a third term in office at the time, held a press conference to express his dissatisfaction with JR Tokai over the decline in the volume of water in the Oi River in relation to the Shizuoka construction zone of the Central Linear Shinkansen. In a press conference, he vented his dissatisfaction with JR Tokai, saying, "They have not expressed any remorse, they have not given any explanation, and they have not promised to bring back the full amount of water.

Before a top meeting with the Shizuoka governor over the linear railway construction, JR Tokai President Kaneko reiterated his stance to solve the water problem as soon as possible.

Earlier, JR Tokai President Kaneko had met with the governor at the prefectural government office and asked for his understanding of the preparatory work before digging the tunnel. However, the prefectural government did not give permission and the construction has not started until today. In a press conference on June 9, 2021, JR Tokai President Shin Kaneko said that he would continue to explain the situation in an easy-to-understand manner at the national expert committee in order to resolve the concerns of the residents. He said that JR Tokai will continue to work hard to solve the problem: "We will do our best".

JR, the National Government, and Shizuoka Prefecture to Discuss the Future of the MLIT Expert Meeting: Discussion Points and Impacts on the Volume of Water in the Midstream and Downstream Areas

Summary and English translation of Japanese Media Report: Source: https://www.at-s.com/news/article/shizuoka/913850.html
Accessed: 2021-06-11

One of the main issues in the Shizuoka Prefecture gubernatorial election to be held on March 20 is the water supply problem of the Oi River due to the construction of the Central Linear Railway Shinkansen. How will the construction of a long tunnel through the Southern Alps, the source of water, affect the use of water in the middle and lower reaches of the river? The following is an overview of the discussions at the expert panel held by the Ministry of Land, Infrastructure, Transport and Tourism, including JR Tokai's explanation and the views of the prefectural government.

The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has held 11 expert meetings since last April. No conclusions were reached in April this year in Tokyo.

JR Tokai's view and explanation

 The Ministry of Land, Infrastructure, Transport and Tourism's Expert Council was set up by the Ministry's Railway Bureau in April last year to provide guidance to JR. Experts in hydrology, tunnel engineering, and other fields are discussing the impact of the tunnel on water use on the following themes:
1) how to return all the spring water from the tunnel to the surface water of the Oi River, and
2) the impact of the tunnel on the groundwater in the middle and lower reaches of the Oi River.
JR also presented a proposal to return spring water generated in Yamanashi and Nagano prefectures over a period of time after the tunnel is penetrated, as a measure to ensure the return of all spring water from the tunnel as requested by the prefecture.

Surface water
JR Tokai's explanation: Can be maintained by making up for the decrease
 According to the flow forecast (assuming the tunnel is not covered with concrete or tarpaulins), surface water in the middle and lower reaches of the tunnel will not decrease. The flow rate will be maintained because the spring water from the Shizuoka section will be returned to the Oi River to compensate for the decrease in surface water upstream.
 However, if the geological conditions and precipitation assumptions on which the projections are based are different, the amount of water flowing out of the prefecture and the amount returned to the Oi River will change, and the amount of surface water in the middle and lower reaches of the river may decrease.
 Considering the safety of the construction, until the tunnel is penetrated, spring water from the sections dug from the Yamanashi and Nagano prefectures will not be returned to the Oi River and will flow out of the prefecture. Even in such a case, if the water from the tunnel in the Shizuoka section is pumped up and returned to the Oi River, the volume of surface water in the middle and lower reaches of the river will be maintained, except in the case of power outages.

Discussions at the MLIT expert meeting: Unclear if the predictions are correct

 If the volume of water inflowing into the tunnel is the volume assumed by JR Tokai, the facility plan is to be able to return the entire volume of water inflowing into the Oi River after the tunnel is penetrated using a conduit tunnel and pump-up.
 However, according to JR's construction plan, the tunnel will be excavated from the Yamanashi side near the border between Shizuoka and Yamanashi prefectures to ensure construction safety, so the spring water will flow out of the prefecture until the tunnel is penetrated, and not all of it will be returned.
 JR's predictions for the flow rate of the tunnel have shown that the amount of surface water will be maintained even if the tunnel water flows out of the prefecture, but the predictions are based on existing data on geology and precipitation, and have not been examined to see if they are sufficient. It is unclear if the predictions are correct.


The prefectural government's view: Conduct additional surveys before construction begins.

  If the spring water from the tunnel were to flow out of the prefecture, it would inevitably have an impact on water use in the middle and lower reaches of the Oi River. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) expert panel has been particularly inadequate in discussing the impact of the spring water flowing out of the prefecture. Additional geological surveys are needed before the start of construction and the accuracy of the estimated amount of outflow from the prefecture needs to be improved.
 In order to avoid the impact of outflow, it is important to have a detailed understanding of the volume of "sudden water inflow" that occurs in large quantities at the tip of the tunnel during excavation. If the estimated volume of water near the border of the two prefectures is low, then the border of the construction area should be aligned with the border of the two prefectures, and the tunnel should be bored downward from the Shizuoka side toward the border of Yamanashi and Nagano prefectures to prevent water from flowing out of the tunnel.
 In the event of a prolonged power outage due to an earthquake or other large-scale disaster, securing the backup power supply needed to pump up the spring water will also be an issue.

Groundwater
JR Tokai's explanation: Water level drop converged in upstream
 According to the analysis of the composition of groundwater in the upstream and middle and downstream areas, the main recharge source of groundwater in the middle and downstream areas is not considered to be groundwater in the upstream area. The extent of groundwater level decrease due to tunnel excavation has converged near the exit of the conduit tunnel.

Discussion by MLIT expert committee: Continuation of water level observation is necessary.
 Once the groundwater in the upstream area becomes surface water, it flows down and becomes groundwater in the middle and downstream areas, so if the amount of surface water in the middle and downstream areas is maintained, the impact on the amount of groundwater will be very small. If the amount of surface water in the middle and lower reaches of the river is maintained, the impact on the amount of groundwater will be very small. We do not know the specific impact and should continue to observe groundwater levels.

The prefectural government's view: Observation should be useful for countermeasures.
 There is no zero impact. A series of observation wells should be installed from upstream to midstream and downstream. It is necessary to increase the number of observation points for groundwater levels and take measures to understand them. It is necessary to increase the number of observation points of groundwater level to understand the situation.

Proposal to return water inflow after penetration
JR Tokai explained that it would take 10 to 20 years to return the same amount of water.
 It is inevitable that spring water from the tunnel will flow out of the prefecture, but instead, after the tunnel is penetrated, the same amount of water will be returned to the tunnels in Yamanashi and Nagano prefectures over a period of time. The estimated outflow to the Yamanashi side is 3 to 5 million tons (equivalent to about 10,000 elementary school swimming pools). It is estimated that it will take 10 to 20 years to return the same amount of water.

Discussions at MLIT expert meeting: Effective risk countermeasures
 Isn't this an effective risk management measure? The secretariat (Ministry of Land, Infrastructure, Transport and Tourism, Railway Bureau) and I thought about this idea. There is an issue of time lag, but the idea is to compensate for the spring water that has flowed out. JR will consult with the prefectural government and cities and towns in the basin regarding the specific method.

The prefectural government's view: The impact cannot be avoided.
 If it takes a long time to return the water, the water in the Oi River will decrease in the meantime, and the impact cannot be avoided. It is questionable whether the amount and quality of water to be returned will be sufficient when considering the possibility of a massive outflow due to a sudden spring. The detailed geology of the area is unknown, and there is a possibility that the situation will not turn out as expected.

Status of the Shizuoka Water & Maglev Tunnel Problem

Post by Miss Maglev »

 Talks on the resumption of construction of the linear railway between the prefectural government, which is concerned that the tunnel construction will reduce the flow of the Oi River, which runs through Shizuoka Prefecture, and JR Central, which is the main operator of the project, are running at a parallel track.
 In April last year, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) set up an expert panel consisting of river engineering experts to mediate between the prefecture and JR Tokai. In March of this year, the ministry released a draft of an interim report that was in line with JR Tokai's assertion that the flow rate in the middle and lower reaches of the river would be maintained if the spring water discharged during the construction work was returned through a water channel tunnel.
 However, Mr. Kawakatsu protested. The expert panel is also discussing the impact on the ecosystem around the construction zone, and the timing of the final report cannot be predicted. Even if the final report is completed, it is unclear whether the prefectural government will accept it, and a MLIT official said, "We have no choice but to carefully fill in the gaps (in the arguments between JR Tokai and the prefecture).

 The suspension of construction on the Shizuoka section has made it difficult to open the Tokyo-Nagoya line between Tokyo and Nagoya in 2027, as originally planned, and the prospect of a new opening remains uncertain.
Kawakatsu stressed to his supporters in Shizuoka City on the evening of the 20th (after his victory in the gubernatorial elections) "the people of the prefecture have entrusted me with the question of whether or not we can protect the natural environment. Afterwards, he told reporters, "I will continue to have a thorough dialogue with JR Tokai".
