How much luggage can I take to study in Japan by boat? What are the restrictions?

You mean the ship from Tianjin to Kobe, right? I did it once. It was really hard, two days and two nights. Don't worry about the weight of the luggage. No matter which ship's flight has no weight limit, take as much as you can. But the problem is that each person can only check two pieces of luggage, and there is only a requirement on the number of pieces, which means you can check two oversized boxes and take a small suitcase with you. Of course, if you have a friend who goes with you and he only checked one piece, you can count it as a piece of luggage on someone else's head. Metal tools can be carried in the consignment box, but it is recommended not to carry so many things. Japan sells everything. There is no need to bring these tools from China, just buy them here. By the way, you'd better take a lot of food before boarding, such as instant noodles and biscuits. The food on the boat is expensive and unpalatable. The water and food in the vending machine cost Japanese yen and are very expensive, if you don't mind. Japan's entry requirements are strict, and agricultural and sideline products such as fruits and meat are very difficult to pass. It is best not to exceed two. Of course, it all depends on luck. Generally, people who enter the customs for the first time will be strictly inspected. You can wrap the vacuum-compressed meat in your clothes, and maybe you can get by. I often do this, hoping to help you.
