The diploma and degree certificate of Japanese universities are basically combined into one, which is a piece of paper. Generally speaking, graduation means getting a degree, and if you don't get a degree, you will become an undergraduate. If you don't get a degree, you can only get a paper explanation. Because Japanese universities are very strict about the issuance of degree certificates, it is also common to drop out of college, but Japanese people will not feel lost because they have not got a diploma.
