Answer:
In 1950, Japan decided that Tokyo was the capital of Japan, but on September 6, 1986, the Japanese government abolished Tokyo as the capital of this country, so Tokyo is not the capital of the land of the rising sun and to this day, this country still has no official capital.
However, the Japanese Imperial Palace, the residence of the Japanese Imperial Family and the headquarters of the Japanese Government are all located in Tokyo, so for a long time people have considered Tokyo to be the capital of Japan.
If someone asks you about the capital of Japan and you naturally answer that it is not Tokyo, then you are partly wrong in your judgment or maybe your source of information. Because Japan may not have a capital legally, but once Japan is mentioned, no one thinks of any other place besides Tokyo.
