A 33-year-old Japanese man has been getting a lot of attention for his ingenious way of putting a roof over his head – asking total strangers to let him sleep over.

Shuraf Ishida has slept in over 500 different homes over the last five years. After quitting his job, he decided to sell all his belongings except for a few essentials that fit into his backpack and travel around Japan using his savings. Normally, accommodation would have ranked highest on his list of expenses, but the 33-year-old man found an ingenious way of putting a roof over his head for free. Every day, Ishida stands in crowded areas sometimes for hours at a time, holding up a sign that reads “Please Let Me Stay Over Tonight!” As weird as it sounds, he almost always finds someone willing to take him in, mostly lonely homeowners in need of someone to talk to.
