We started as admirers. We became caretakers. Now we make sure the homes people fall in love with from afar actually thrive.
OUR STORY
It began with Old Houses Japan — a quiet passion project born from wandering Japan's back roads and discovering the traditional properties that most people had forgotten. Thatched-roof kominka tucked into mountain valleys. Lattice-front machiya lining narrow Kyoto lanes. Akiya sitting empty in fishing villages, waiting for someone to care again.
We started sharing these houses online, and something unexpected happened. People from around the world fell in love with them. Buyers from the US, the UK, Australia, France, Singapore — they found their dream property in a country they'd visited once or twice, signed the papers, and became owners of a piece of Japan.
Then came the hard part. Owning a house 6,000 miles away is not the same as living in one. The roof tiles shift in a typhoon and there's nobody to notice. The garden overgrows until the neighbors complain. The tax notices arrive in Japanese and sit unopened. Slowly, the houses these owners loved so much began to deteriorate — not from neglect of spirit, but from the sheer impossibility of being present.
We watched it happen enough times that we couldn't just keep listing houses. We had to start caring for them too.
That's why we built MonoHaus. Same love for these properties. Professional management to keep them alive. Every inspection report, every contractor call, every tax filing — handled by people who understand both the culture of these houses and the reality of owning one from abroad.
We care for our own 100-year-old property the same way we care for yours. That's not a marketing line — it's the reason this company exists.
大切にしていることWhat we stand for
Every yen accounted for. No hidden fees, no vague line items, no surprises three months in. You see exactly what we spend, why we spent it, and what it accomplished. Your monthly reports read like a letter, not a spreadsheet buried in fine print.
We treat every property like our own — because we know what it means to care about a house that's been standing for decades. The right contractor for the job, not the cheapest one. The repair done properly the first time.
Bridging the distance between you and your home. Six time zones, a language barrier, and a different legal system — none of it should stop you from feeling connected to the property you chose. We're your eyes, ears, and voice on the ground.

私たちOur team
Our team operates in Japanese and English every day — negotiating with contractors in Osaka in the morning, sending inspection reports to owners in London by afternoon. We live where your properties are.
