On February 22, 20 15, the "Nogizaka46 New Project" was put forward, which was later named "torii Office No.46". When it was officially disclosed on August 2 1, it was renamed as "Tanban 46".
Tansaka, as a place name, is located near Tokyo Port Area, Roppongi New Town and Asahi TV Station. It is the center of the industrial tourism network in the port area, and it is more suitable as the representative place of young people's culture than the Saka people in torii (1688- 1703) who opened in Lu Yuan period.
The original Japanese word "Tanban" is Tanban, whose simplified Chinese character is Tanban, which is pronounced as [j ǔ] in Mandarin; In Japan, it is also simplified as キョ (pentatonic コ) and けやき"(keyaki).
