Dekotora!

Dekotora is short for Decoration Truck, and apparently in the late 70's and 80's they were quite popular. I first heard about them from Pink Tentacle quite some time ago, and I see them from time to time, but usually driving and I can't get a good shot, but today I saw one in Mitaka parked by the station.

It's not the most dramatic example I've seen, but it was also in my neighborhood, no somewhere showing off.
