How much does it cost from Guangdong to Hokkaido, Japan?

This is very expensive. If the air ticket is non-stop, go to Japan at 4000, and then take the domestic flight in Japan1000-2000 or so. If you don't fly directly, Guangzhou Baiyun Airport will transfer to Shanghai, then go to Thailand or Hong Kong, and then take a domestic flight in Japan. Of course, Japan can take the Shinkansen bus or something, which is much cheaper.
