I come from Weifang, Shandong. I want to go abroad to Japan. What procedures do I need to go abroad again?

Get a passport first, and then get a Japanese visa.

As for the visa, it depends on what kind of visa you are applying for, such as a tourist visa, a visit visa, a work visa, a business visa or an immigrant visa. The materials required for each visa are different. You can check it on the website of the Japanese Embassy. Then, according to your purpose of going abroad, choose your own visa type and prepare materials. After you have prepared the materials, you can send them to the Japanese embassy.
