I am Romanian and live in Fukui (more than 1 year visa) and I am going to a conference in China in September. Can I apply in Tokyo for visa or should I apply to Osaka consulate ?
For bussines trip visa I need :
1) passport
2) application form with passport photo
3) allien registration in Japan
4) invitation from China

Do I need also confirmation for booking reserevation from hotel and round-trip ticket ? Anything else ?

Thank you.
