Asagaya (阿佐ヶ谷?) is a residential area of Tokyo located in Suginami ward (one of the 23 wards or boroughs of Tokyo) west of Shinjuku. Main access to Asagaya is via the Chūō-Sōbu Line, 12 minutes by train from Shinjuku station.
At present the Asagaya area is divided latitudinally into North (阿佐ヶ谷北?, Asagaya-kita) and South (阿佐谷南?, Asagaya-Minami) by the Chūō-Sōbu Line. Boundaries for this area are roughly the same as those for Asagaya Village (阿佐ヶ谷村 Asagaya-mura?), dating back to the Edo Period. Longitudinally, the Japanese Zelkova serrata tree-lined boulevard, Nakasugi-dōri (中杉通り?), divides Asagaya, running from Ome-kaido in the south to Waseda-dōri in the north. From around the Taishō period people began moving from the Yamanote area (central Tokyo) into the suburbs including Asagaya. At present, the area around the station is considered upper-level Tokyo suburban housing due to its space, greenery, convenience to central Tokyo—and numerous Shōtengai, the largest of which originates from the South exit of Asagaya Station.
