The Hokuriku Shinkansen is a high-speed railway line (Shinkansen) planned to connect Tokyo and Osaka City via the Joshinetsu and Hokuriku regions, and is one of the five maintenance Shinkansen lines. As of March 14, 2015, the section between Takasaki Station and Kanazawa Station is open. In addition, although Takasaki Station is the starting point in the "Railway Handbook", the starting point for the maintenance Shinkansen is Tokyo, and for areas east of Takasaki Station, the Tohoku Shinkansen is between Tokyo Station and Omiya Station, and Joetsu is between Omiya Station and Takasaki Station. It is shared with the Shinkansen, and all regular trains run to Tokyo Station via the Joetsu Shinkansen and Tohoku Shinkansen. In the passenger information, the section between Tokyo Station on the Tohoku / Joetsu Shinkansen-Tokyo Station including Takasaki Station-Kanazawa Station is referred to as the "Hokuriku Shinkansen".

Overview

The Hokuriku Shinkansen was announced in 1972 (Showa 47) by the "Basic Plan to Determine the Routes of Shinkansen Railways to Start Construction" pursuant to the provisions of Article 4, Paragraph 1 of the National Shinkansen Railway Development Law, and was announced in 1973 (Showa 48). It is one of the five routes (so-called maintenance Shinkansen) whose maintenance plan was decided on November 13th. Construction was temporarily frozen due to the financial deterioration of the national railway, but construction started between Takasaki Station and Karuizawa Station in 1989, and the Shinkansen between Takasaki Station and Nagano Station was constructed in October 1997. It opened for the first time. After the construction of some sections between Nagano and Kanazawa was started by the super express system, all sections were fully standardized, and the section between Nagano Station and Kanazawa Station was opened in March 2015. The Railway Construction and Transportation Facility Development Support Organization constructs and owns railway facilities, and is operated by East Japan Railway Company (JR East) between Takasaki Station and Joetsu Myoko Station, and West Japan Railway Company (JR West) between Joetsu Myoko Station and Kanazawa Station. Has been done. The facility management boundary between JR East and JR West is the starting point of 177 km 950 m from Kanazawa and Takasaki at Joetsu Myoko Station. At the time of opening in 1997, Nagano Station was the end point, and the Hokuriku Shinkansen did not reach the Hokuriku region until the extension in 2015, so the name for passengers has changed (see history for details). The Hokuriku Shinkansen is the first and still the only Shinkansen line with the same name under the jurisdiction and operation of multiple railway companies. In addition to the Hokuriku Shinkansen, JR West also operates the Sanyo Shinkansen, but this is the first time that the Shinkansen line operated by one railway company is not directly connected. The Hokuriku Shinkansen is the first maintenance Shinkansen to start construction, and various new technologies are used to reduce construction costs even though it is a line that goes through areas with different power frequency frequencies, mountainous areas, and heavy snowfall areas. Construction between Kanazawa Station and Tsuruga Station will begin in 2012, and is scheduled to open at the end of 2023 (Reiwa 5). For the section between Tsuruga Station and Shin-Osaka Station, which is an unconstructed section, a rough route for environmental assessment was announced in May 2019 (the first year of Reiwa).
