The Japanese know the tune very well from the traditional graduation song “Hotaru no hikari”, a very pre-war sounding song about a student studying by the light of a firefly and then going on to serve his country, and most are unaware that it is not Japanese. How a graduation song became a end-of-sale-of-Louis-Vuitton-for-the-day song I’m not sure, but it does have a kind of ending feeling to it.
