It has been finally announced that Akanishi Jin's first U.S. solo single will be released on November 8th. The single will be the one that has been rumored to be it for a while, Test Drive, which he worked with U.S. artist Jason Derulo with.
From what else I can get from the photo of the newspaper article this is coming from the single will be released on iTunes (not sure if it's U.S. only or not) and it seems like for his U.S. career he will be going by the name JIN.
It was also announced that on December 7th he will release a mini album in Japan.

Can't say I'm surprised by the name change, it seems to be the big worry when artists come over to try to break in to the U.S. music industry whether or not the U.S. audience will take to a "foreign" sounding name. And it's not a big change either as it's just his first name which is hard to mispronounce in English.
It's also nice to see that he does plan on making sure he gives his Japanese fans something as he works on his American career.
