Unobtainium. Avatar doesn’t seem quite so stupid now.

its fake the one at the bottom is in Sendai, but still that do those Japanese build them from ?

At a place I work we had some engineers from a related company in Hiroshima make a business visit to here. We went downtown into old town and they remarked at all the nice old buildings. One of our interns, former air force, still with the short hair, still in his 20’s asks “Do you have any old buildings where you are from?” There is this awkward silence with all of us looking very embarrassed except for the kid, oblivious. The ever polite Japanese head engineer of the visit, possibly old enough himself to remember first hand, nicely replied “No, unfortunately we were unable to protect many of our old buildings. You are very fortunate to have been able to keep so many of yours.” I don’t think we ever let the kid live that one down, it really had just slipped his mind.
Anyhow, neat pic, if badly labeled.
