Editing Shinkansen (section)

=== Planned lines ===
* The extension of [[Hokuriku Shinkansen]] to [[Osaka]] is proposed, with the route via Obama and Kyoto selected by the government on 20 December 2016.<ref name="railwaygazette.com" /> Construction is proposed to commence in 2030, and take 15 years.
* [[Nishi Kyushu Shinkansen]] has been built to full Shinkansen standards between Takeo-Onsen and Nagasaki, with the existing narrow-gauge line from Shin-Tosu to Takeo Onsen to remain as narrow-gauge track, although there is a proposal to build the section between Shin-Tosu and Takeo Onsen to full Shinkansen standards. In 2018, the [[Ministry of Land, Infrastructure, Transport and Tourism]] released [[cost-benefit analysis]] results to compare and contrast full Shinkansen, [[Mini-shinkansen]], and [[Gauge Change Train]] for this section.<ref>{{cite web |date=30 March 2018 |title=九州新幹線（西九州ルート）の整備のあり方に係る調査について |trans-title=About the investigation about the maintenance of the Kyushu Shinkansen (West Kyushu route) |url=https://www.mlit.go.jp/report/press/tetsudo03_hh_000081.html |url-status=live |archive-url=https://web.archive.org/web/20220705064325/https://www.mlit.go.jp/report/press/tetsudo03_hh_000081.html |archive-date=5 July 2022 |access-date=29 August 2021 |website=mlit.co.jp |language=ja}}</ref>
