Quicky: in the city and alongside of the express way in the city, not much green can be found. But here halfway til Narita, things are much greener and less concrety.
Also, here it is obvious again that most hill sides and sound barriers, so to say, are concrete enforced. It shows, but I suppose that’s only practical.
Note: as you may have surmised, I have not experienced any earthquakes during my stay.
