The idea of changing Edo's name to Tokyo appeared in Nobunobuyuki Sato, a famous scholar at the end of Edo's life, "The Secret Strategy of Confusion" written in Zheng Wen for six years (1823). Sato recorded the following thoughts in his book: In order to make Japan active on the world stage, it is necessary to move the capital to Edo and name it Tokyo, and name Osaka Xijing to form three capitals: Tokyo, Xijing and Kyoto.

Influenced by Sato, Kubo Junichi suggested that Edo be renamed Tokyo. 1September, 868 (July in the fourth year of Keio (the first year of Meiji)), according to the imperial edict of "Edo is called Tokyo", Tokyo was established to govern the occupied area of Edo-CHO, and the name Tokyo was used.

Although the expanded materials have the notation of Tokyo, there is no formal law on pronunciation. Although "とぅきやぅぅぅ" (Wu Yin) is used as a regular pronunciation, there are not a few people who pronounce it as "とぅけぃ" because of the pronunciation habit of Chinese pronunciation in the first half of the Meiji 1920s.

Due to the development of Japanese newspapers, people's information has been widely exchanged. In the national Putonghua textbookNo. 1, the reading table in Tokyo is marked as "トーキョー" to avoid confusion.

Moreover, regarding the writing methods of Chinese characters, until the early Showa period, there were also cases of confusing the use of "Dongcuo". Xun is a variant of Jing. The word "Xun" was used to distinguish it from Tokyo (Luoyang or Kaifeng) in ancient China, and later the same Beijing word was used.
