What advanced technology does Japan monopolize

The Chinese mostly define monopoly as the direct way. In fact there are more hidden forms.

Japan's direct monopoly industry directly: digital consumer electronics monopoly up to 99% (such as: digital cameras, camcorders, printers, copiers, etc.)

Automotive electronics, automotive parts, elevators, high-end machine tools, medical equipment, steel equipment, etc.. People monopolize up to 70% or more.

Indirect monopoly: China's home appliance companies, automobiles, chemicals, etc. are using Japanese technology. For example, Chinese air conditioners are Japanese compressors.

Network monopoly, with Japan's Softbank as the head of the monopoly group, under the banner of YAHOO! (everyone thinks it is the United States) Taobao, Alibaba, etc.. You can search for Japan Softbank and you will see that he invests in Chinese companies.

The Japanese consortium is so powerful that it can be said to be everywhere, in a shadow way. We can't feel it.
