This is a parking lot in the downtown of Tokyo. The reason the ceiling is arched is because it is under the elevated train rails that run through the city.
The floors and walls have not been overly remodeled, giving the space an old time feel, and the “No Smoking” sign in Japanese and “LOW GEAR ONLY” written in English on the wall is making the space looks like a scene from an old movie.
These gaps in the city, if not utilized, can become a safety and hygiene issue, with weeds growing and homeless people occupying them. Since Japan is a small country, the way of utilization is well thought out. Some places are fancy and remodeled into shopping areas, while others are simple ways like this.
What kind of gaps in utilization do you see in your city?
