Interesting move if it comes off for him, he would adapt well given he can speak the language.

Interesting rule to make players have to choose which nationality they are after 22 years. Would force a lot of dual nationals to pick japan so they could keep playing there. Not a bad thing just interesting

He already  played there before so it wont be such a culture shock 

Good luck to the lad

cerezo usually go for pretty boy foreigners like nichols or forlan (dual national or not, this kid will be viewed by most in japan as a foreigner)
