My friends and I found an abandoned Ryokan/Hotel/Onsen that was allegedly owned by Yakuza and was just left there when they stopped paying the rent. It was really cool wandering around seeing old school laser discs for movies and the karaoke room with sealed bottles of Asahi beer scattered on the floor. I'll see if I can get some pics up for you.
And yes, I live in a very rural area of Japan.
Add them to your odyssey thread. If you can sneak a pipe in here and there it's legit. We want more!
