Personally, I think the corresponding relationship with domestic universities is as follows (of course, at all levels, I feel that Japan is slightly stronger):
Top: Tokyo University (Peking University), Kyoto University (Tsinghua University)
Super category: Osaka University (Fudan University), Nagoya University (Shanghai Jiaotong University), Northeastern University (Zhejiang University)
Super Category: tokyo institute of technology (University of Science and Technology of China), Waseda University, Keio University, hitotsubashi university.
First-class: Hokkaido University (Nanjing University), Kyushu University (Xi Jiaotong University), Tsukuba University (Harbin Institute of Technology)
Focus: Kobe University, Yokohama National University and other Japanese national universities (corresponding to other 985 universities in China)
Note: Waseda University, Keio University and hitotsubashi university are all private universities, so it is not convenient to compare them directly with China. But the comprehensive strength is first-class in Japan. Waseda is overvalued in China for propaganda reasons.
