is a 1963 hit song performed by a Japanese singer Kyu Sakamoto. It was written by lyricist Rokusuke Ei and composer Taku Izumi. Izumi won the Japan Record Award. The song was originally written for a musical of the same title in 1960.
This song was covered by many singers, including Begin (as an end theme for the anime Futatsu no Spica) and Ken Hirai. It was covered by noise rock band Ground Zero for their 1997 album Plays Standards.
The song, among other cheerful songs of Kyu Sakamoto, was often heard in Japan after the 2011 Tà Âhoku earthquake and tsunami. This included a series of versions by 71 actors and singers (among which was Tommy Lee Jones), for Suntory beverage company commercials, coupled with the song "Ue o Muite Arukà Â". Shikao Suga also covered the song for charity.
