I don't know why they aren't charging for other things. They have the 30 yen admission, but they just found a new attraction and could charge a separate entrance fee for it. We already know they have a niche survivalist crowd fanbase.
  • 30 yen General Admission + 5000 yen and a liability waiver = Take the dragon's quest! Already built!
  • Slightly raise the price of merchandise
  • Put in one of those slingshot things that the parks charge you 3500-5000 yen for each ride. Low construction costs.
  • And get the bus stop changed!



But I guess that runs afoul of the good-hearted nature of this park's residents.
