What is "azabu"

is an area within Minato in Tokyo, Japan, built on a marshy area of foothills south of central Tokyo. Its coverage roughly corresponds to that of the former Azabu Ward, presently consisting of nine official districts: Azabu-Jūban, Azabudai, Azabu-Nagasakachō, Azabu-Mamianachō, Nishi-Azabu, Higashi-Azabu, Minami-Azabu, Moto-Azabu and Roppongi. It is known as Tokyo's most expensive upscale residential district; many artists, business people, and celebrities reside there.
