Shinagawa Seaside View Tower
This high rise apartment is close to Tokyo bay and 1 minute walk from Shinagawa Seaside station (Rinkai line) and 10 minute from Aomonoyokocho station (Keikyu Hon line). This area is still a developing zone so the rent can be lower however Rinkai line directly takes you to major stations like to Shinjuku within 19 minutes. 24 hrs Aeon supermarket is nearby and there is even a nursery school in the building.
