Why did the Yomiuri Shimbun die out?

Tokyo is the core of Japan and Chiyoda is the core of Tokyo. The Imperial Palace, the Japanese Parliament Building, the Supreme Court and most of the central provincial offices where the Japanese emperor lived are located in Chiyoda. Chiyoda is not only the political center of Japan, but also the place with the highest land price in the 23rd district of Tokyo, with an average land price of 6,543,800 yen/m2 (about 6,543,800 yuan+2,000 yuan).

The most famous streets in Chiyoda are the Palace, the National Assembly, the Prime Minister's residence, the headquarters of the Liberal Democratic Party and nagatacho, the seat of the Democratic Party. Shimonoseki where Guanting Street and the Metropolitan Police Department are located; Marunouchi, known as "Mitsubishi Village"; The Yomiuri Shimbun, Sankei Shimbun, Nikkei News, etc. are the headquarters of several major Japanese news agencies, as well as Komachi, where the Supreme Court is located. In addition, the Japanese budokan, Tokyo National Museum of Modern Art, the old headquarters of Japanese TV, Akasaka Prince Hotel and Akihabara Electric Street are all located in Chiyoda. This place has always been the leader of land price in Tokyo.
