Why do Japanese photos always have an unreal feeling?

This is because different countries have different understandings of the tone of photos, and then the designs of lenses, photosensitive components and image processors are different. For example, Japanese photography is more exquisite and soft, while German photography prefers thick and thick. In fact, Japanese Nikon has always been called "the European flavor of Asia".

You can't tell who is fake and who is real. Even the German taste of the widely admired German lens is actually a strong exaggeration of the blues and orange tones. In fact, to say the authenticity of color reproduction, on the contrary, Canon in Japan has great advantages.

Supplementary answer:

Looking at this photo provided by the landlord, it is obvious that this is caused by inaccurate white balance and has nothing to do with anything else.

In addition, the landlord may not see many photos. In fact, a large number of photos taken by Japanese equipment are of high quality, and one or two photos really don't explain the problem.
