Is Uketsu Strange House Based On A True Story?

I went on a binge playing ‘Uketsu Strange House’ over the weekend. As far as horror games go, it’s really good. I wouldn’t call it a documentary or anything, but it certainly has a very realistic feel to it. The developers must have studied up on a lot of Japanese ghost stories because the main entity in the game has a backstory that echoes that of a classic onryō, but it was all reworked to be something new and original. My paranormal investigating friend noted that the use of salt in the game mirrored the use of salt in Shinto purification rituals. Even though the house and all is completely fictional, the developers did a good job of including a lot of cultural touchstones to make the game feel more real.

I had no idea what ‘Uketsu Strange House’ was going into it, but the first thing that struck me was how incredibly believable the world of the game was. It feels so much like a urban legend that has been reworked into a full length story. All of the creator interviews that I read spoke to the abandoned houses in Japan that have very dark histories, often of tragic events. Haikyo (abandoned places) is a huge subculture in Japan and this game feels like it perfectly captures that sense of morbid curiosity and fear. They also drew inspiration from folk tales of yūrei (ghosts that are tied to a location), but emphasized that the game is entirely fictional. But playing the game late at night with creaking floorboards and all, it’s hard to tell what’s just the game and what actually sounds like an old, haunted house.

What is fascinating to me though is that despite it not being based on a true story it is very grounded in reality. The house and its various spaces are mostly modeled after a Japanese mansion from the Taishō era with hidden rooms and secret passages. The game’s creepy atmosphere is inspired by real life abandoned locations, and there are many examples of such locations all over the world that are similar to the ones found in the game. There is even a giant community of folks on Reddit who document and explore such locations, and some of the screenshots from the game have been compared to real life locations which are basically identical. The director of the game was interviewed on a podcast and in it he joked that all horror feels true when you’re alone in the dark. This is definitely the feeling I got while playing through the game. Not really sure if that was what the developers were going for or not, but it’s definitely what I got.

I don't have a source to cite for this, but a general consensus in all serious fan translations and lore communities I'm a part of is that the stories are the author's original work. The author's notes for each volume go into some detail about his process and cite influences such as Junji Ito and certain European horror novels, but no historical research or alleged 'true stories' from case files.

This seems to be another one of those “Internet telephone game” situations where someone said “this feels so real it could be true” and then others kept saying “I heard it is true” until finally everyone just believed that it was true. As with many pieces of effective horror, the mythology surrounding it now far exceeds the actual content of the work.
