“Big in Japan” is the opening track on the 1999 Tom Waits album, Mule Variations. The album received widespread critical acclaim and was a modest commercial success, going to #30 in the US, #9 in the UK, and most popular in Norway at #1. Ironically, it wasn’t big in Japan, and didn’t chart there. Mule Variations won a Grammy for Best Contemporary Folk Album, and is regarded as one of the greatest albums of all time.
