Do you know an organization called 'Amya'?

There's an organization in Japan called Amya (暗夜). It's a private horror event group that buys haunted houses where actual incidents occurred, conducts safety tests, and then holds experience events for the public. You can stay overnight for the experience, and it seems to cost around 470,000 KRW for 1-5 people, with additional charges for more. When I checked before, there were extra fees for things like video recording and internet uploads. Also, they give you missions, and it seems like they refund the cost if you complete them! I'd love to go and experience it someday!
