Koto Minamisuna Housing 南砂住宅 occupies a large rectangular plot of land in Koto-ku (map). The closest train station is Toyocho Station 東陽町駅, which is just 9 minutes from Otemachi.
To the north of the danchi are two former canals that are now walking paths / parks:
- Yokojukkengawa Water Park 横十間川親水公園 (Green path) よこじっけんかわしんすいこうえん
- Sendaiborigawakōen 仙台堀川公園 Green path
- (for a map of these, and other walking paths, see: Walking on water: the underground rivers of Tokyo 東京の地下河川や運河の地図)
