History
Nangō-Jūsan-Chōme Station (station number T15) is on the Sapporo Municipal Subway Tōzai Line in Shiroishi-ku, Sapporo, Hokkaido. It opened on 21 March 1982 with the Tōzai Line's eastern extension from Shiroishi to Shin-Sapporo. The Shiroishi-ku article records that the ward's settlement began in 1871, when retainers of Katakura Kojūrō — the lord of Shiroishi Castle in the Sendai domain, defeated in the Boshin War — emigrated to Hokkaido aboard ships including the Kanrin Maru and broke ground at "Motsukisappu" (the present-day central Shiroishi area). The Hokkaido Colonisation Commission judge Iwamura Michitoshi, impressed by their work ethic, named the village "Shiroishi" after their home castle. Shiroishi village was absorbed by Sapporo City in 1950, and when Sapporo became an ordinance-designated city in 1972 it was reconstituted as Shiroishi Ward.

Notes
The Shiroishi-ku article notes that when the Tōzai Line was extended east from Shiroishi to Shin-Sapporo in 1982, three new stations — Nangō-Nana-Chōme, Nangō-Jūsan-Chōme, and Nangō-Jūhatchōme — were opened along the ward's main east–west thoroughfare, Nangō-dōri.
