No, those are not hobos.

In America, if you see somebody sleeping on a bench in broad daylight then they are most likely a hobo or "drag rat", as we so eloquently call them in Austin. This is why I was very perplexed when Mr. Sekine took us to the Emperor's Palace in Kyoto and there were hobos sleeping on every single bench! Turns out, people just like to sleep whenever and wherever they can! Japanese work so hard, and so much, but never sleep so they're damn good at sleeping standing up on the train, on a bench in a park, while visiting a museum, in the kitchen while eating, during a speech, or while writing a letter.
I think I will utilize this when I get back to America, too bad I didn't come by this tactic while I was still in college!
