I am going to shanghai, then to tokyo and then back to beijing.Now I have only one entry visa. Can I apply for a China visa in Japan without Japan residence visa?

Im e.u. citizen, from cyprus, going to shangai,NEXT WEEK then to tokyo and then back to beijing.i have only one entry visa cause my passport expires less than a year.11 months.in japan as i know i dont need a visa.so i read that to get a china visa you must have a residence or extended japan visa.

1)do i need 1 year validy passport?
2)do i need japan residence visa???

thx
