Infrastructure (eg water, sewer, electrical supply to the house) should be the landowners' responsibility. 

I have a 10x8 shed that I use exclusively to store real estate materials and supplies.

Personally when I’m working on a project time is money and I don’t have the ability to wait around to get supplies.

That gets worse as you get farther out of the cityTLDR: values depreciate, inflation has gone basically nowhere in Japan for a long time, the supply of housing is pretty good compared to demand (unlike the US) and that's because of flexibility with rezoning and development, taxes on rental income are high.
