Too many articles on the Linear Linear issue ? Sorting out the "pros and cons" for those who are not familiar with the issue
----------
The construction of the Linear Central Shinkansen Line is underway with the aim of opening in 2027. However, Shizuoka Prefecture has refused to allow construction of the Shizuoka section of the Minami-Alps Tunnel (tentative name), which will penetrate the prefecture, due to a "water problem," making the 2027 opening date unrealistic.
Significance of Construction
The Linear Central Shinkansen Line is currently under construction by Central Japan Railway Company (JR Tokai), aiming to open between Shinagawa and Nagoya in 2027 or later. The Linear Shinkansen refers to a magnetic levitation railroad that uses superconducting magnetic levitation linear motor cars and has a maximum design speed of 505 km/h. The Linear Shinkansen will run from Shinagawa to Nagoya in "as fast as 40 minutes.
The line is scheduled to connect Shinagawa and Nagoya in "as fast as 40 minutes". The final construction of the line is planned to reach Shin-Osaka Station, which is scheduled to open in 2037 at the earliest. The shortest planned opening date is 2037, with Shinagawa to Shin-Osaka in 67 minutes at the earliest.
JR Tokai believes that the Linear Shinkansen's construction is significant because it will create a huge metropolitan area by directly connecting the three metropolitan areas of Tokyo, Nagoya, and Osaka in a short period of time, and will provide an opportunity to greatly improve Japan's international competitiveness. In addition, the report explains that the Tokaido Shinkansen is deteriorating over time, and that the Linear Chuo Shinkansen will be realized as soon as possible to double the main arterial lines connecting the three metropolitan areas and serve as a backup line, as a drastic measure against large-scale disasters. Furthermore, if the Linear Chuo Shinkansen is realized, the trains corresponding to the "Nozomi" of the Tokaido Shinkansen will be transferred to the Linear Chuo Shinkansen, and the "Hikari" and "Kodama" trains, which have many stops, will mainly operate on the Linear Chuo Shinkansen,
This will increase the number of Shinkansen trains that stop at stations that Nozomi trains used to pass through, and will contribute to the improvement of opportunities for passengers to use such stations and the revitalization of the Tokaido Shinkansen line.
For Nozomi, the stops between Tokyo and Shin-Osaka are limited to Shinagawa, Shin-Yokohama, Nagoya, and Kyoto, and the stops between these stations are
Shizuoka Prefecture (Atami, Mishima, Shin-Fuji, Shizuoka, Kakegawa, Hamamatsu)
Gifu Prefecture (Gifu Hashima)
Shiga Prefecture (Maibara)
The train does not stop at any of the stations in Shizuoka Prefecture.
The total project cost of the Linear Chuo Shinkansen between Shinagawa and Nagoya will be increased by 1.5 trillion yen from the originally planned 5.5 trillion yen to 7 trillion yen in April 2021.
The data released at that time showed that the total project cost of the Linear Central Shinkansen between Nagoya and Nagoya would be 7 trillion yen. According to the data released at that time, JR Tokai's long-term debt balance after 2027 will reach approximately 6 trillion yen, a situation that will continue for several years. However, JR Tokai has said that, based on its past track record of repaying its long-term debt JR Tokai believes that the company will be able to withstand the situation for several years. However, JR Tokai has indicated that the company can withstand the situation for several years.
The Tokaido Shinkansen, operated by JR Tokai, was owned by the Shinkansen Holding Corporation in 1987, when JR Tokai was established as a result of the privatization of Japan National Railways, and JR Tokai leased the Shinkansen to operate the line. However, in 1991, JR Tokai purchased the railroad facilities related to the Tokaido Shinkansen for approximately 5 trillion yen. This resulted in a long-term debt of approximately 5.4 trillion yen, but JR Tokai has continued to repay the debt in annual installments of approximately 140 billion yen with the passenger revenue generated by the Tokaido Shinkansen, and by FY2015 the balance of the long-term debt was less than 2 trillion yen.
Furthermore, while operating income (non-consolidated) in FY1991, when the Tokaido Shinkansen was purchased, was 287.6 billion yen, it increased to 667.7 billion yen in FY18 before the corona. Given these facts, JR Tokai Co, believes that it can withstand long-term debt of around 6 trillion yen because "the company's management strength is stronger than it was when it bought the Tokaido Shinkansen."
Arguments of Linear Opponents
In contrast, there are some deep-rooted opponents of the Linear Central Shinkansen. The most influential argument is from Shizuoka Prefecture, which claims that since the Shizuoka construction section will dig a long tunnel in the headwaters of the Oi River in the Southern Alps, tunnel spring water seeping from the headwaters will flow out to the Yamanashi side, causing a drought in the Oi River. Shizuoka Prefecture has been reluctant to approve the start of construction of the Shizuoka construction zone, saying that it would interfere with water supply in the lower Oigawa River basin, which would be a matter of life and death for the prefecture's residents, and that the Oigawa River system "must protect the 'water of life' for 620,000 people.
Other major arguments include
The time advantage of 40 minutes to Nagoya is blown away by the time required for security checks, which are as strict as those at airports.
JR Tokai's demand forecast is excessive and Linear Line will not be profitable. The amount of investment for the Linear Line is equivalent to the total cost of nursing care insurance, so we do not agree with the plan. Some of them say that the project is not a good idea.
Although it has not yet been officially announced what exactly the method will be when boarding the Linear Shinkansen, the idea is that the Linear Shinkansen has a fatal flaw in that it will require body and baggage checks comparable to those on airplanes when boarding the train. Most of the line between Shinagawa and Nagoya is a tunnel, and trains are operated automatically under central control. With only three conductors on board the train, which has a capacity of approximately 1,000 passengers, what would happen if explosives or deadly weapons were brought on board the train, which is traveling at 500 km/h through the dark tunnel?
To prevent such a situation, security checks comparable to those at airports are required before boarding, and for this reason, the train must arrive at the station inspection area at least 30 minutes before boarding. In addition, since each station will be located deep underground, it will take an extra 10 to 20 minutes to get down to the underground platforms, and when these times are factored in, the 40-minute time advantage of the linear train will be lost.
As for JR Tokai's demand forecast being excessive and the Linear Line not being profitable, even if the Linear Chuo Shinkansen starts service, JR Tokai's sales will not increase because the passengers who used to use the Tokaido Shinkansen will only be split between the Linear Chuo Shinkansen and the Tokaido Shinkansen. If JR Tokai raises prices to increase sales, the number of passengers will decrease, and JR Tokai will ultimately not be able to finance the investment in the Linear Chuo Shinkansen. Furthermore, JR Tokai's projection that the combined number of passengers on the Tokaido Shinkansen and Linear Chuo Shinkansen will increase by 26% by the time the line opens in Shin-Osaka in 2037 is an exaggeration in a society with a declining population.
Furthermore, some argue that the total cost of long-term care insurance in Japan is 9.7 trillion yen, which is equivalent to the amount invested in the Linear Chuo Shinkansen, and therefore, is not in favor of the Linear Shinkansen. Although the total cost of long-term care insurance and the construction cost of the Linear Shinkansen cannot be compared in terms of cost and investment, there is no place in the world where one can spend such a huge amount of money and travel at a speed of 500 km/h in the darkness of a tunnel.
Economic Impact of "Approximately 160 Billion Yen
In Shizuoka Prefecture, the "Oigawa River water problem" tends to be the main focus of attention, and the benefits of the Linear Shinkansen construction are rarely reported in the media. However, in fact, the construction of the Linear Shinkansen will have an economic impact of "about 160 billion yen" on Shizuoka Prefecture over 10 years.
When the Linear Central Shinkansen begins service, demand for transportation between Tokyo, Nagoya, and Osaka will shift from the Tokaido Shinkansen to the Linear Chuo Shinkansen, creating a surplus in the Tokaido Shinkansen's transportation capacity.
The Ministry of Land, Infrastructure, Transport and Tourism estimates that if this extra capacity is used to increase the number of Shinkansen stations in Shizuoka Prefecture to about 1.5 times the current level, the economic effect in Shizuoka Prefecture, which has no Shinkansen station, will amount to 167.9 billion yen over 10 years until 2046, when the Linear Central Line will begin service at Shin-Osaka, through improved convenience and increased tourists from outside the prefecture. The report also estimates that it will create a total of about 15,000 jobs in Shizuoka Prefecture.
