YesAsia's description of Seasons
Akanishi Jin may be working hard to make it in the United States music industry, but he's also staying close to home. Just after releasing his first English-language single Test Drive, Jin is ending his 2011 in Japan with his second Japanese solo single Seasons. Written by Jin himself, the ballad is his touching tribute to all the people he loves. The single includes the studio version of The Fifth Season (which Jin performed at his concert tour) as B-side track.
