The following lines are under construction. These lines except [[Chūō Shinkansen]], called {{ill|Seibi Shinkansen|ja|整備新幹線}} or ''planned Shinkansen'', are the Shinkansen projects designated in the {{ill|Basic Plan of the Shinkansen Railway|ja|建設を開始すべき新幹線鉄道の路線を定める基本計画}} decided by the government.

* [[Hokkaido Shinkansen]] from {{STN|Shin-Hakodate-Hokuto|x}} to {{STN|Sapporo|x}} is under construction and scheduled to open by 2038.<ref name=":0" />
* [[Chūō Shinkansen]] (Tokyo–Nagoya–Osaka) is the first [[maglev]] Shinkansen line, which has been under construction since 2014. JR Central originally aimed to begin commercial service between Tokyo and Nagoya in 2027. However, in 2024, Central Japan Railway Co President Shunsuke Niwa said that due to construction delays a 2027 opening was now impossible and it is not expected to open until at least 2034.<ref name="auto1">{{Cite web|title=Japan rail operator gives up plan to launch maglev train in 2027|url=https://japantoday.com/category/business/update1-japan-rail-operator-gives-up-plan-to-launch-maglev-train-in-2027|access-date=30 March 2024|website=Japan Today|date=30 March 2024|language=en-GB|archive-date=30 March 2024|archive-url=https://web.archive.org/web/20240330000706/https://japantoday.com/category/business/update1-japan-rail-operator-gives-up-plan-to-launch-maglev-train-in-2027|url-status=live}}</ref><ref name="auto" />
