建設中止（東北新幹線に乗り入れ）となったが、一部区間では用地買収が済んでおり、新宿駅地下にもスペースが確保されている（都営地下鉄新宿線と京王新線、都営地下鉄大江戸線の新宿駅は上越新幹線の駅空間を避けるために深い位置に作られている）。

The construction was cancelled (because the Joetsu Shinkansen line was connected to the Tohoku Shinkansen line at Omiya Station), but for some sections of the line, the necessary land has been procured, with space for the underground Station acquired as well (Shinjuku Station of the Shinjuku line of the Toei metropolitan subway, that of the Keio Shinsen line (the new Keio line), and that of Shinjuku Station of the Oedo line of the Toei metropolitan subway are constructed in deeper places to avoid the Station space for the Joetsu Shinkansen line). - Wikipedia日英京都関連文書対訳コーパス
