Week End (Gen Hoshino song)

"Week End" (Japanese pronunciation: [ɯiːkɯeꜜɴdo]) is a song by Japanese singer-songwriter and musician Gen Hoshino from his fourth studio album, Yellow Dancer (2015). The song is the album's sole promotional single, released for exclusive airplay on the Japan FM League on October 20, 2015, and was also promoted with a listening video. Written and produced by Hoshino as the theme song to the morning news program Mezamashi Saturday  [ja], it is a pop-like dance song that draws influence from black music genres, such as R&B and soul. Lyrically, Hoshino in falsetto encourages listeners to dance freely.

The song was received positively by album reviewers, who praised its sound as exciting. "Week End" peaked at number 21 on the Billboard Japan Hot 100 and was certified gold by the Recording Industry Association of Japan (RIAJ) for paid digital downloads. The song was particularly successful in airplay, ranking on Billboard Japan's year-end radio songs lists for both 2015 and 2016. It had its debut performance on the music program Music Station, after which Hoshino featured the song on the 2016 Yellow Voyage tour with dance performance from Elevenplay.
