“Japan” is the second single from Famous Dex’s debut album, Dex Meets Dexter. It has reached a peak of #28 on the Billboard Hot 100.

Originally previewed in the album trailer, the J Gramm-produced song was finally released on March 16th, 2018.

The song began to gain traction after Roy Purdy posted a video dancing to it, sparking a new trend called the #JapanChallenge:

Dex is well-acquainted with Purdy, being spotted in photos together (Dex himself has also attempted the #JapanChallenge, paying homage to Purdy in the caption), and embraced the trend by reposting a video of LeBron James Jr. doing the #JapanChallenge.
