Hello my name is Bar and I'm from Israel. I want to issue a visa to China from Tokyo.

Bar, if you go to China for sightseeing purpose, first, you need to prepare the relevant documents: your passport and copy of its data page, a completed application form, and passport-style photo, your residence permit in Japan or Japan visa and its copy, proof of your financial support, your employment certificate, travel itinerary, round trip air tickets, and hotel booking record. If you have an invitation letter, the tickets and hotel reservation are not needed then.
Next, submit the application to the CVASC in Tokyo.
Usually it costs JPY9,000 per person.
