The purpose of this study is to clarify the forming process and the distribution of the Imperial Estates in central Tokyo since the Meiji Era, and to examine the importance of these lands in the formation of modern capital. The study is based on the investigation of documents and materials, and is mainly refered to the description on "Teishitsu-Rinyakyoku Gojunenshi" [fifty years history of Imperial Forestry Bureau]. First of all, we made the list of "the first category" of the Imperial Estate, mostly consisted with palaces, which existed in pre-war period in the central Tokyo. Secondly, we made the distribution map at 3rd, 14th and 23rd year of Meiji, 12th year of Taisho and 12th year of Showa Era, and analyzed its transition. Pointing out that the Imperial Estates had relations with the Europeanization of the capital at the middle of Meiji Era and the establishment of Scenic Zone and Aesthetic Zone, We examined the importance of the Imperial Estates in the urban history at Tokyo.
