Governor Requests Disclosure of Linear Central Shinkansen Construction Progress


Governor Kawakatsu has written to JR Tokai demanding disclosure of the progress of the construction of the Linear Central Shinkansen, which Shizuoka Prefecture has not approved the start of construction, saying that it is necessary to provide local residents with correct information and gain their understanding before proceeding.

While Shizuoka Prefecture has refused to allow construction of the Linear Shinkansen line to begin in the prefecture due to concerns about the impact of the line on the Oi River, the prefecture joined the "Construction Promotion Alliance" formed by prefectures along the line in July this year to promote the opening of the line between Shinagawa and Nagoya in 2027, and Governor Kawakatsu has been active in this movement by visiting construction sites in Kanagawa, Yamanashi, and other prefectures. Governor Kawakatsu has been active in this movement, including visits to construction sites in Kanagawa and Yamanashi prefectures.

Against this backdrop, Governor Kawakatsu issued a letter dated November 25 requesting JR Tokai to disclose the progress of construction in neighboring municipalities.

The document states, "In order to realize the Linear Shinkansen Line as soon as possible, it is necessary to provide local residents with correct information on the disposal of overburden soil generated by the construction work and measures to prevent water shortage while obtaining their understanding.

The document goes on to say that "the progress of projects in each prefecture is very informative," and calls for disclosure of the progress rate of construction, the rate of land acquisition, and the details of efforts to address issues at facilities in other municipalities that are being developed, such as the Kanto rail yard in Kanagawa Prefecture, where the governor pointed out delays in acquiring a site.

They have also written to the Ministry of Land, Infrastructure, Transport and Tourism with the same content, requesting guidance from JR Tokai.

Where they say the letter demanded information it reminded me of the American democracy that had so many problems trying to please everybody the French HSR builders in California decide to go home.

I believe there is a balance between peoples rights and the common good.

Just ask the Chinese who have far more experience in tunnels how to drive it.

[JP] The Shizuoka Water & Maglev Tunnel Problem

Post by Miss Maglev »

 On November 11, members of Shizuoka Prefecture's expert committee exchanged opinions with the mayors of 10 cities and towns in the watershed concerning the reduction in the flow of the Oi River due to the construction of tunnels for the Shizuoka section of the Linear Central Shinkansen Line. The committee members stated that the preconstruction boring study that JR Tokai is willing to conduct "is not necessary at this time," while the leaders of the 10 cities and towns in the watershed expressed their opinion that the study is worthwhile because it will help alleviate the concerns of local residents.


 Four members of the subcommittee were present for the exchange of opinions. Yuichi Morishita, visiting professor of geology at Shizuoka University and chairman of the subcommittee, pointed out the concern that spring water could flow out of the prefecture during the investigation stage and explained that the feasibility of the Tashiro Dam (Shizuoka City) intake control plan proposed by JR Tokai as a measure to reduce water flow must first be discussed.

JR Tokai President: "Shizuoka construction zone will have an impact on the opening date of the Linear Shinkansen".


In a response to Governor Kawakatsu's November 25th written request to JR Tokai to disclose the progress rate, land acquisition rate, and issues at construction sites in other prefectures, JR Tokai's President Kaneko issued a written response on December 14.
In the written response, he did not mention specifics regarding the progress of construction and land acquisition, which Governor Kawakatsu requested to be disclosed, stating that they are "publicized on our website.
Instead, he reiterated his view that "the Shizuoka construction section is the one that will affect the opening of the Shinagawa-Nagoya line in 2027," and asked the prefectural government for cooperation in starting construction as soon as possible. He reiterated his view that "at this point, the Shizuoka section is the one that will have the greatest impact on the opening of the Shinagawa-Nagoya line in 2027.

リニア新幹線トンネル工事 国の有識者会議が今後の論点示す
Linear Shinkansen Tunnel Construction: National Expert Panel Discusses Future Issues



A meeting of national experts to discuss environmental conservation in Shizuoka Prefecture in connection with the construction of the Linear Central Shinkansen tunnel has been held, and it was indicated that future issues to be discussed include analysis of the impact on stream organisms and alpine plants in the Southern Alps and the impact on organisms at the remaining soil dump site.

The JR Tokai Corporation is aiming to open the Linear Central Shinkansen in 2027, but Shizuoka Prefecture has not allowed construction to begin in the prefecture, citing the impact on the ecosystem of the Southern Alps.
The sixth meeting of experts established by the Ministry of Land, Infrastructure, Transport and Tourism was held in Tokyo on March 20, and based on previous discussions and hearings from related parties, the future issues were summarized.
According to the report, it was indicated that when changes occur in the groundwater level due to the tunnel construction, the flow rate of each stream and the habitat of the organisms inhabiting the streams and alpine plants in the Southern Alps should be analyzed to confirm the impact on the streams and alpine plants, and that the pathways by which moisture is supplied to the plants should be analyzed by observing changes in soil moisture for alpine plants.
It was also indicated that the impact of the construction work on plants at the overburden dump site would be analyzed.
They will ask JR Tokai to disclose data on these issues and discuss measures to avoid or reduce the impact at the locations where the impact will occur.
After the meeting, Takashi Mori, Vice Governor of Shizuoka Prefecture, said, "The issues presented today have not yet been fully discussed, and we cannot judge whether they are sufficient or insufficient. We will report the results to the prefectural government's technical committee and consider whether or not they include what the prefecture is seeking.

JR Tokai has released an animated video on its website to introduce measures to return tunnel spring water to the Oigawa River in connection with the Oigawa River water problem caused by the Linear Central Shinkansen construction project. However, the animation does not mention anything about the spring water flowing out of the prefecture, which is still under discussion by an expert committee of the Shizuoka Prefecture Expert Council, and the prefecture has expressed concern that the content is misleading.

 The video is titled "Overview of the Southern Alps Tunnel (in Shizuoka Prefecture) and how to return water gushing into the tunnel to the Oigawa River" and is approximately 3 minutes long. The video shows a three-dimensional image of the measures to return spring water from the advanced and main tunnels in the Shizuoka construction area to the Oigawa River through the conduit tunnel, and states, "Water from the tunnel will be returned to the upper reaches of the Oigawa River during and after construction, so that the amount of water flowing in the middle and lower reaches of the river will not decrease.
 A prefectural official pointed out that "there is spring water that will flow out of the prefecture during construction, and we are in the middle of discussions over how to handle it, but no explanation has been given," and he viewed this as problematic because it "gives the impression that the problem has already been solved.
 The company's Shizuoka Public Relations Office stated, "We created the video to show the measures in an easy-to-understand manner and to deepen understanding.

On December 21m 2022, President Kaneko commented: "At this point, I cannot say when the Linear Central Shinkansen will begin operation, because construction of the Shizuoka construction zone cannot begin due to opposition from Shizuoka Prefecture. I am sorry for the people in the various prefectures who have high expectations for the Linear Central Shinkansen, but we are going to do what we can to make it happen".

リニア静岡工区の環境保全巡り本格議論を開始、国の有識者会議が論点整理
Full-Scale Discussion Begins on Environmental Preservation in Shizuoka Linear Zone, Japan's Expert Panel Discusses Issues


The Ministry of Land, Infrastructure, Transport and Tourism's panel of experts to study the environmental impact of the Shizuoka section of the Linear Shinkansen's Southern Alps Tunnel (Chairperson: Futoshi Nakamura, Professor at Hokkaido University) has begun full-scale discussions focusing on the flora and fauna of the high mountain areas, tunnel spring water, excavated soil storage areas, etc.

At a meeting held on December 20, 2022, the panel members approved a draft discussion point compiled by the MLIT, the secretariat. At a meeting held on December 20, 2022, the committee members approved a draft of discussion points compiled by the Ministry of Land, Infrastructure, Transport and Tourism, the secretariat of the project. With the Shinagawa-Nagoya section of the line not expected to open in 2015, discussions will be hurried toward an early start of full-scale construction.

 In the Shizuoka section, the Ministry of Land, Infrastructure, Transport and Tourism established an expert panel in 2022 after Shizuoka Prefecture and JR Tokai could not come to an agreement on the impact on the Oigawa River of excavating a mountain tunnel that straddles Yamanashi, Shizuoka, and Nagano prefectures. The expert panel released an interim report summarizing the results of its analysis of the Oigawa River and groundwater flow. It concluded that the flow rate in the middle and lower reaches of the Oigawa River could be maintained if measures were taken, such as returning tunnel spring water to the Oigawa River.

 Therefore, since June 2022, the expert panel has conducted hearings with local governments and landowners in the basin, as well as site inspections. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has summarized three issues for future discussion: the impact on aquatic life, the impact on alpine plants, and the impact on the surrounding environment due to disposal of excavated soil and discharge of tunnel spring water, and presented them at the December 20, 2022 meeting. Although committee members suggested revisions to the specific details of each point, it was agreed to proceed with discussions centered on the three points.

Accessed January 10, 2023

 The Ministry will compile analysis and evaluation methods for each point of contention, and establish specific measures and management targets for avoiding or reducing environmental impact. For example, for aquatic organisms and alpine plants, the local geology and groundwater will be investigated by manual drilling and electrical prospecting, and the extent to which groundwater near the surface, spring water, and pond water are affected by fluctuations in groundwater levels and rainfall, respectively, will be verified. Since it is difficult to comprehensively examine plants, animals, and their distribution areas, representative sites will be selected to simulate the magnitude of impact.

 In addition, the meeting will also clarify management methods during construction and compensatory measures in the event of an impact. Shizuoka Prefecture, which will participate in the project as an observer, plans to hold a meeting of the prefectural expert committee on biodiversity in January 2023 to closely examine the contents of the December 20 meeting.[/i]

[JP] The national expert panel on the Linear Central Shinkansen tunnel construction

Post by latestnews »

Following the presentation of the future issues to be discussed by a national expert panel on the Linear Central Shinkansen tunnel construction project, an exchange of opinions was held at the prefectural government's expert panel to discuss environmental conservation in the prefecture.

In December, an expert panel established by the Ministry of Land, Infrastructure, Transport, and Tourism presented future issues to be discussed regarding the Linear Central Shinkansen Line, which JR Tokai plans to open in 2027, including an analysis of stream flow and habitat conditions of inhabiting organisms.

In response, the prefectural government's expert committee held an exchange of opinions. A committee member commented on the stream survey, saying, "Analyzing the stream is very time-consuming. On the other hand, another committee member commented that the proposal made at the experts' meeting to survey only a portion of the streams by categorizing streams with similar characteristics, rather than all of them, was insufficient because the organisms in each stream differ depending on the amount of rocks and gravel, etc. Another member of the committee expressed a negative opinion, saying, "It may not be sufficient because the organisms differ from stream to stream depending on the amount of rocks and gravel.
Other comments included, "The basic premise is to show avoidance or mitigation of impacts, but we need to discuss what we would do if there were impacts.

The prefectural government will compile a document requesting the experts' meeting based on the opinions of the committee members.
Vice Governor Takashi Mori said, "We have a common understanding of the contents of the experts' meeting. We would like to present the contents that the prefecture is seeking at the experts' meeting.

リニア大井川水問題 JRの十分な説明なく 田代ダム案、議論加速を【解説・主張しずおか】
Linear Oigawa River water problem without sufficient explanation by JR: Tashiro Dam proposal, debate must be accelerated



Info by Political Affairs Department, Mr. Takaya Ohara


The JR Tokai's April 2022 proposal to reduce the intake of water from the Tashiro Dam as a measure to reduce the Oigawa River's water level in conjunction with the construction of the Linear Central Shinkansen tunnel has gone over the years without any progress in the discussions. In the discussions held so far by the Shizuoka Prefecture Expert Committee, JR Tokai has not provided sufficient explanation as to whether the proposal is feasible even during the drought season in winter. This is a core topic that will determine whether linear construction and water resource protection can be compatible, and those involved should accelerate discussions to obtain a successful proposal.

 JR Tokai explained at the technical committee meeting last December that even with the highest projected outflow out of the prefecture (0.68 tons per second), the proposal would be approved because it would be possible to control water withdrawal by the same amount as the outflow during the winter drought season. However, JR's calculations did not gain the understanding of the committee members because it was unclear whether the minimum amount of water withdrawal required by TEPCO, which manages the dam, was taken into account in order to maintain the power generation facilities.

 According to data obtained by the Shizuoka Shimbun through an information disclosure request to the Ministry of Land, Infrastructure, Transport and Tourism, in 2005, when the annual precipitation at the Igawa point was the lowest in the past 10 years, the water intake at the Tashiro Dam was the lowest in March and April, with the daily average intake between March 20 and April 6 at 1.52-1.08 tons per second. Even taking into account the decrease in river flow caused by the tunnel excavation, the proposal is theoretically valid as long as more than 1.05 tons per second of water is being withdrawn.

 However, whether TEPCO would approve a situation in which the amount of water taken in would be infinitely less is another matter. A member of the technical committee also pointed out, "In what form will TEPCO's assurance of cooperation be presented? TEPCO has indicated in previous interviews that they will begin concrete discussions after JR Tokai obtains the approval of the parties concerned, and that they will not negotiate directly with the prefecture or other parties.

 The only way is for JR to enter into talks with TEPCO after obtaining the agreement of the "Oigawa Water Utilization Related Council," which consists of water users' groups and cities and towns in the basin, and other parties.
 It is reasonable for the basin to hope that the Tashiro Dam will continue to control water intake after the linear construction, saying, "If there is water that can be returned, we want it permanently returned," but if the issue of water rights is entered into, there is a possibility that TEPCO will hesitate to cooperate with the Tashiro Dam proposal. The Tashiro Dam proposal is a measure limited to the construction period, and should be separated from the discussion of water rights.

 JR suddenly announced last October that it would conduct high-speed long advanced boring from Yamanashi across the border with Shizuoka Prefecture, and the prefectural government and the technical committee are opposed to the idea. If they dare to do so, it could spoil the discussion of the Tashiro Dam proposal, and they should exercise restraint now.

Linear Shinkansen: Governor Kawakatsu: Letter to Prime Minister Kishida Requesting Details of Study


Regarding the Linear Central Shinkansen, Prime Minister Kishida has announced that he plans to compile the results of a study by the end of this summer on how to increase the frequency of stops on the Tokaido Shinkansen in Shizuoka Prefecture after the opening of the Linear Shinkansen.

At the New Year's press conference, Prime Minister Kishida announced his intention to compile by summer the results of a study on how much the frequency of stops of the Tokaido Shinkansen can be increased at stations in Shizuoka Prefecture after the opening of the Linear Central Shinkansen Line.
Governor Kawakatsu announced at the regular press conference on March 24 that prefectural officials sent a letter to Prime Minister Kishida's office on the morning of March 24, requesting information necessary to inform Shizuoka Prefecture of the study.

In the letter, the governor requests that information be presented on the benefits to the prefecture, such as the number of "Hikari" and "Kodama" trains on the Tokaido Shinkansen and the number of stops at stations in the prefecture, as well as information on the difference in fare between the "Linear" and "Nozomi" trains during the opening phase of the Shinagawa-Nagoya line.

[Note: Situation in context explianed here: https://www.researchgate.net/publicatio ... aglev_Line ]

They also request an explanation of the impact of social changes on the project, claiming that social conditions such as a declining population, soaring energy prices, and a decrease in human flow due to online penetration will have a severe impact on the Linear project.

Meanwhile, when asked if he intends to discuss directly with Prime Minister Kishida, he stated that he would definitely like to have direct discussions with him if he is invited.

 In response to Prime Minister Fumio Kishida's plan to conduct a survey on increasing the number of stops of the Tokaido Shinkansen in Shizuoka Prefecture after the opening of the Linear Central Shinkansen, Governor Heita Kawakatsu sent a letter to the Prime Minister on January 24 requesting that the impact of the opening of the Shinagawa-Nagoya line and the Shinagawa-Osaka line be studied separately. The letter is four pages in A4 size and is addressed to the Prime Minister of Japan.

 The letter is four pages in A4 size. The Tokyo Prefectural Office delivered the letter to Prime Minister Kishida's office on the same day. The letter requested an explanation of the results of the survey on six items, including the difference in fares between the linear and Shinkansen lines, the number of trains per hour, and the number of stops at stations in the prefecture, after separating the sections where the line will open.

 He also pointed out that the acquisition of land for the Kanto rail yard has not been completed and that the construction of several substation facilities has not yet begun, as "there are matters that are making the partial opening in 2007 difficult.

 He also pointed out that the acquisition of the site for the Kanto rail yard has not been completed and that the construction of several substation facilities has not yet been started.

Governor Kawakatsu's "Theater" Playing with the Linear Project: "Red Light" in Shizuoka: No Construction Started and Line to Open in 9 Years
January 27, 2023 07:00

The construction of the Linear Central Shinkansen Line is at the mercy of one governor. Heita Kawakatsu, governor of Shizuoka Prefecture, who is concerned about the environmental impact of the project, has refused to allow construction of the construction zone in the prefecture to begin, putting a "red light" on JR Tokai's plan to open the line between Tokyo and Nagoya in 2027. Not only JR Tokai, but also the national government and local governments along the JR Tokai line are struggling to respond to the changing issues and provocative statements. The local community has begun to "disassociate itself from the governor," and the national government has begun to get more involved in an effort to resolve the situation. Will the siege widen?

The linear line is in a crisis of survival," Kawakatsu told reporters at a regular press conference late last year. Kawakatsu explained his perception of the current situation at a regular press conference at the end of last year.

JR Tokai announces geological drilling survey near prefectural border


On January 25, JR Tokai announced its plan to conduct a boring survey to investigate the geology near the Shizuoka Prefecture border for the tunnel excavation work being carried out on the Yamanashi Prefecture side of the Linear Central Shinkansen Line at a special committee in Shizuoka Prefecture that is considering environmental measures for the Shizuoka construction zone. Committee members and Shizuoka Prefecture officials expressed concern that the survey could cause groundwater to flow into the Yamanashi side, but JR sought their understanding, saying, "We will proceed while taking countermeasures.

 JR had previously stated that it would conduct borehole investigations in Shizuoka Prefecture, but committee members objected, saying that this was premised on the start of construction (which they had not yet approved), and JR changed its policy, saying that it would not do so until measures to restore the water that would leak out from the investigation had been established.
