Although this law was abolished later, it was not because Tokyo ceased to be the capital, but because the objective of the law (construction of capital) was accomplished and it was necessary to expand the area of city improvement from the capital to the capital and its surrounding region; the succeeding law, 'national capital region improvement law,' has a continuity and unity with the abolished law.
のちに同法は廃止されたが、廃止理由は、東京都が首都でなくなったからではなく、あくまで同法の目的（首都の建設）が達成され、整備の対象を「首都」から「首都とその周辺地域」に広げるための発展的なものであり、後継の首都圏整備法とは連続性、一体性を有するものである。
