I watched about homeless people in Japan. I didn't know that some people have choosed to live as homeless and homeless is one of lifestyles.
I have felt sorry for them at first. I used to go to Sendai to go to a cram school and I often came across a homeless man. He was always sitting on a bench, reading a tour guidebook...
It is true that many homeless people have no choice but to lead such life, but the man in the video probably tries to enjoy his life no matter how hard his situation is.
