Hotaru no Hikari, meaning Light of Fireflies, was published in Japan in 1881 with lyrics by educator Chikai Inagaki set to the Scottish melody of Auld Lang Syne. It became a standard at elementary and middle school graduation ceremonies and is traditionally sung to close the NHK Kohaku Uta Gassen on New Year's Eve. In daily life many Japanese shops and stations play an instrumental version at closing time, which is why online listeners associate the tune with respectful goodbyes, finished work and the end of the day.
