Why is City Pop Nostalgic?

City Pop is a nostalgic genre of music for many people in the West for several reasons. Firstly, City Pop was popular in Japan during the late 1970s to the mid-1980s, a time when Japan was experiencing a period of rapid economic growth and cultural expansion. This era is often referred to as the "Bubble Economy" in Japan and is remembered as a time of great optimism and prosperity.
