Sudachō (須田町?), officially Kanda-Sudachō (神田須田町?), is a district of Chiyoda, Tokyo, Japan, consisting of 1-chōme and 2-chōme. As of April 1, 2007, its population is 1,019. Its postal code is 101-0041.
This district is located on the northeastern part of Chiyoda Ward. It borders (across Kanda River) Soto-Kanda and Kanda-Sakumachō on the north, on the east, Kanda-Kajichō and Kajichō on the south, and Kanda-Awajichō, Kanda-Ogawamachi and Kanda-Tachō on the west.
Sudachō once had a terminal which served for a number of the Tokyo City Streetcar lines. It is one of the few areas that survived the bombing of Tokyo in World War II, resulting in many historic buildings still existing.
At one time Creatures Inc. had its headquarters in the Nintendo Kanda Building (任天堂神田ビル Nintendō Kanda Biru?) in Sudachō.
