In fact, whether it is traditional or simplified. The important thing is that when you arrive in Japan, the name written is the same as that on the seal. For example, there is no simplified Liu in Japanese, only traditional Liu, so for convenience, I still write traditional Liu, and the seal is also carved in traditional Chinese. Think about it, if you use simplified Chinese characters, what should you do when all kinds of Japanese input methods can't be output? But there is a problem at this time, that is, the name on the passport is simplified Liu. What should I do? It doesn't matter. Passports are not often used. It is basically used when buying air tickets by plane. You can use simplified Chinese characters then, and the ticket doesn't need to be stamped! In short, when you leave a card in Japan, you must write your traditional surname or simply write your English name. I wish you a smooth and happy life studying abroad!
