Japanese ruined themepark

I can't believe I never posted these before. I discovered these photos about 5 years ago and thought I was in dream world bliss... Japan has lots of amazing ruins - I think these ones are in the north of the main island...






I have a thing for ruined themeparks - ferris wheels seem to dot the landscapes of my ex Soviet travels a lot... The bottom one is one in Sevan, Armenia that we drove past, and the top one is in Armenia too...
