Since the Peace Treaty with Japan (Peace Treaty signed in San Francisco) was concluded in September 1951 and Japan came back officially as an independent country, "Kimigayo" was performed by an orchestra every day at the end of radio broadcasting by Japan Broadcasting Corporation (NHK).
1951年9月に日本国との平和条約（サンフランシスコ講和条約）が成立し、正式に日本が独立国に復帰した際以来、日本放送協会のラジオ放送で連日放送終了後にオーケストラによる『君が代』の演奏が始まった。
