I want to travel to Japan for a week or so, mainly attracted by the haunted house of Fuji in Japan. But I heard that Japanese food is very expensive, and I'm not a rich second generation. ...

Fuji Paradise is located in Hekou Lake, Yamanashi Prefecture, Japan. The local consumption is not high, which is basically about 700 yen for a bowl of Lamian Noodles and 500 yen for a box lunch (100 yen is about 8 RMB). So look at how many meals you want to eat, and you can work it out. There are many options for booking air tickets and accommodation in China. Just choose one from the travel agency. In addition, strictly speaking, you can't bring meat and fruit into Japan, but if you put them in a consignment box, they will generally not be inspected unless you are unlucky. Really can't. Bring some instant noodles or something.
