Dear, you go to PRC for tourism purpose, right? If yes, you should provide those documents including your passport and copy of its data page, the application form, a passport-style photo, your residence permit in Japan, round trip air tickets and accommodation booking record. Afterwards, submit your application to the embassy of PRC to apply for it.
