What is "hibiya"

is a geographic name covering a part of Chiyoda Ward in Tokyo. The area along Hibiya Street ( National Route 1) from Yūrakuchō to Uchisaiwaichō is Hibiya district. Hibiya is used in some local place names such as Hibiya Park and Hibiya Station. Hibiya was a ward named Kōjimachi before Tokyo City was restructured. The outskirts of this district are reclaimed from the ocean, so the name of "hibi" of Hibiya is derived from the facility for the laver of nori made of bamboo whose name is also "hibi".
