Minamisuna is a district of Koto Ward in the east of Tokyo. It has a station (Minamisunamachi) on the Tokyo Metro Tozai Line.
In the park next to the station, there is a marker pole showing the water level when the area was inundated by the sea in a particularly severe typhoon in the 1950s – it’s well over head height so if you come here in a typhoon, bring a life jacket!
To the north of the park there is a large Jusco supermarket (one of the closest to central Tokyo) and an enormous branch of the DIY store ‘Doit’. If you have (or have hired) a car, this a great place to load up on supplies for weekend projects.
