My passport was issued in Xinjiang, and my hukou is also in Xinjiang, but I am studying in Chengdu. Where do I want to apply for a Japanese visa?

Xinjiang passport and Japanese visa shall be handled by the Japanese embassy or agency in China. You should find the nearest one. There is no one in Chengdu. The latest one is handled in Chongqing, which has a consulate general.
