This is Kyoto University dormitory built almost a century ago, to be precise in 1913.Student squatters who live there pay an extremely low price: ¥2,500, about $27. Constructed at the southern edge of Kyoto University's Yoshida Campus, the dormitory was self-administered by the students who were in charge to select new applicants to live there.The building is maintained by students themselves, even though they did some little upgrades (like Ethernet cables in the corridors that lead to each room), but any of major building repairs have never been conducted and the building can't be considered safe, plus hygiene conditions are quite unsatisfactory. 
Well, you’ll see it all inside the post.
