1. Compared with Japan, we are foreigners, so these foreigners need a Japanese guarantor to enter Japan. Do you? You can live without it. Safety is not guaranteed and the cost is too high.

If you can't speak Japanese at all, I suggest you learn a little before you go. The intermediary recommends you a job, but is not responsible for life and other issues. At least ask for directions. You bought a Japanese dictionary and a map, but you can't find the place. It's just a gobbledygook Even if the place is right in front of your eyes, you don't know it. Not to mention when eating, if someone picks you up at the immigration office, you don't even know what you are talking about.

Although I like going abroad to Japan very much, it will be better for my Japanese. You said that if you go to a Japanese hotel to work through an intermediary, even if China trainees go to Japan, they can only work as dishwashers and waiters in some inferior restaurants. Do you need to work in a hotel if you don't know Japanese?
