What about on the top of buildings? Over parking lots ect? Any time you shade a black top it really helps with heat soak
You do have to be careful though, sometimes those tarpaper roofs are trying to keep heat inside the building, or trying to keep lines from freezing in the winter.
That being said, there's plenty of places in Japan where you could throw up a canopy of solar panels tied into the grid.
Railways :-)

150km/h is high speed? The Japanese will laugh you out of the room. And the prototype is designed for just 70km/h.
They will shake apart if proper trains run over them.
Try running faster in mountains. Good luck.
Highspeed train to plane route?
Problem is always the landing
Was also going to say high ways
tokyo has a lot of buildings, put it on top of every building possible.
Yes. I'm sure that will be the way they go in the end. But businesses want to do it as cheap as possible. Make a quick buck for the lowest possible costs as usual. On roofs is a little more complex. Legislation is probably needed.
farms?
