According to the Constitution of Japan, it is a symbolic emperor system.
Isn't symbolism like verbalization?
New water flows every second in the river, so the river one second later is a different object from the river we just saw.
However, as soon as the name “○○ River” was attached, what was a phenomenon that fell apart moment by moment came to be recognized as a continuous flow.
Thanks to the emperor system, Japan can be recognized as a continuous nation with a long history.
In the days when Prince Shotoku controlled politics, Japan, when Taira Kiyomori ruled, during the Tokugawa shogun, and during the Liberal Democratic Party government, everyone was a continuous “country of Japan” under the emperor.
On the other hand, for example, saying “China's 4,000-year history” is full of lies.
The People's Republic of China is a country formed quite recently.
The Chinese government says, “The South China Sea has been our country's since ancient times,” but that “our country” didn't exist that long ago.
