Back from some hectic adventures, I’m standing in front of this house that seems straight out of a fevered dream. Its walls, blackened like ashes from a fire, are covered with enigmatic messages drawn in white or yellow. I wait a while, watching … then, finally, dare to go inside.

First encounter: mystery and tension
I knew nothing of this intriguing house. Its dark walls and apparent desolation imply long abandoned. But very soon my attention is captured by the painted messages, sometimes still fresh:



- “Are you OK or 脳 ?”
(pun on 脳, meaning “brain” and pronounced “nō”) - “Control is vitality”
- “If you need anything, ring for five seconds”
- “Can you live in this house?” (in theory… yes?)
Puzzled, I venture inside. An oppressive atmosphere takes hold, but it’s calm, so I take some pictures. I go upstairs and come across an unlikely sight: an eerie-looking elderly man sitting in front of an old television. Panicked, I rush out again. He didn’t see me! Phew.
Once outside I wait, out of sight, in the hope of capturing a better impression of the occupant. And then I get lucky: he leaves his house on a bike, which I video on my mobile. Admittedly, out of context, it’s me the psycho rather than him! 😆
A living house: graffiti treatise


Despite its dilapidated appearance, this house is far from abandoned. Its owner still lives there, constantly transforming its walls into a personal manifesto, tinged with social criticism. Layers of black paint regularly cover old graffiti, like flipping pages in a public diary.
Among the messages, I manage to decipher these:
- “Police use medication to manipulate people”
- “Bankruptcy in 1998”
- “I even ate grass”
The houseowner is rumoured to have lost everything during the collapse of financial conglomerates in the 1990s, such as Yamaichi Securities. This bankruptcy is thought to have ruined his life, pushing him into making a giant treatise of his house.
Walls of suffering
Perhaps more troubling, some messages address health issues:

- “Left hemianopia after removal of right brain”
- “All my bones were severed”
These phrases may reflect real suffering, interpreted through a prism of paranoia and conspiracy theories, such as “non-consensual surgery” or “wave manipulation”. Is this graffiti a cry of alarm or a desperate form of poetry?

Visitors also report strange sounds coming from the house: messages broadcast in a loop, weird squeaks. A rumour persists that the owner has a device to “project his thoughts”, reinforcing the mystical aura of the place.
A private and living sanctuary
The Black House isn’t only unusual, it’s the living testimony of a broken life … or of fierce resistance! Intriguing as much as disturbing. Theories abound on Japanese forums. Was this a rich investor ruined by the economic bubble? A misunderstood artist? A marginal visionary? A madman?





The house is very popular with fans of unusual places. But this is a private living sanctuary, not a tourist novelty. If you pass through this remote corner, don’t expect a guided tour, be respectful. On Google Maps the house is blurred – the occupant probably wants to be left in peace?
Your theory?! 🤔
