[Japanese Music] Masterpieces of 2000s Pop: A Collection of Hit 00’s J-POP Songs

As we find ourselves in the mid-2020s, it’s surprising to think the 2000s were already more than 20 years ago.

It’s fascinating that music and culture from that era are being rediscovered and celebrated—particularly through the so-called “Y2K” boom—led by younger generations who were born around that time.

In this article, we’re focusing on Japanese hit songs from the 2000s, gathering beloved tracks that colored the era under the broad theme of pop music.

Especially in the early 2000s, the momentum from the ’90s carried over, giving rise to massive nationwide hits.

We hope not only younger listeners but also those now in their 30s, who likely spent their youth in the 2000s, will enjoy reminiscing with these nostalgic classics!
