Tokyo dialect
Historically, Kanto dialects lacked "keigo" (honorific speech). However, because of its connection with Kyoto and the stratification of urban society, the Tokyo dialect now has a refined keigo system. The Yamanote dialect is primarily known for an extreme use of keigo and the keigo copula "zamasu" or "zāmasu", sometimes "zansu", derived from "gozaimasu". The courtesy imperative mood "asobase" or "asubase" is also a well-known keigo word from the traditional Tokyo dialect. For example, "Won't you please wait for me?" translates to for "o-machi kudasai" in standard Japanese, and "o-machi asobase" in the traditional Tokyo dialect.
