Chinese national needs Visa for Okinawa?

My friend in China, a China national and myself, a Malaysian, is planning to visit Okinawa. We would like to find out if my China friend would require to apply for a VISA before entering Okinawa only,

We have received various advise from different sources giving us different information, we would like to get an affirmation from you so we can plan out holiday properly.

Look forward to hearing from you.

Okinawa is Japan. Same visa requirements, same everything.

I think the advise you received is about single visa or multiple visa for Chinese visitor to Okinawa.

Okinawa is not a special admistrative region, like Jeju Island (South Korea). The above posters are correct, that entry requirements there are the same as for the rest of the country.
