exploring ruins

The thing I keep coming back to with old, empty buildings isn’t the decay itself. Graffiti and smashed-in interiors actually make me lose interest fast. What I’m there for is the world the building still carries — the smell, the chipped finishes, the way a kitchen is laid out, the shape of a desk.

From details like that you can almost imagine the era the room came from: how someone moved through their day, what they cooked, the kind of life the place was for. It comes through the senses, not through reading about it. There’s something there from a time the present doesn’t carry, and I can’t really explain past that.

This post is the practice around that — how people find these places, what the rules and risks look like, what’s in the bag, and one thing Japan does differently from the rest of the urbex world.

finding them

Most of what people call “urban exploration” happens at a desk. The split is something like 90/10 — most of the work is in maps and historical records, and the visit itself is a short confirmation of what you already know is there.

The shape of the work is the same across cultures: satellite imagery → modern map → historical map → business records → owner records. A few visual cues are worth learning to read at the satellite layer — overgrowth where the roof and wall meet, rust-colored roofs that should be gray, an empty parking lot where there should be cars, entrances that have been boarded over or fenced off.

And the geography is unsurprising once you notice it: rail lines and canals from the 19th and 20th centuries are where most of the heavy industrial stuff sits, because that’s where it was put.

The tooling differs by region. In English-speaking practice it tends to be Google Earth Pro for the satellite timeline, Geoportail for old French maps from the 1950s, and Old Maps Online as an index across libraries.

In Japan the desk setup is unusually strong. The modern layer is the GSI base map (chiriin-chizu), and the historical layer is Konjaku Map on the Web, which covers 59 regions from the Meiji era forward. Lost villages mostly find themselves: a settlement marked on the 1900s sheet that isn’t on the modern one.

For owner lookup, blue maps (zenrin) get you to a property’s lot number, and the official registry service gets you the rest. You can, legally, look up who owns any given plot of land in Japan from a website.

The numbers behind the school side of the supply are public too. MEXT’s closure surveys put it at around 470 schools closed per year, accumulating to 7,583 in a fifteen-year stretch, of which about 19.7% (1,295 schools) sit with no assigned use — neither demolished nor repurposed.

The closed school is its own small genre in Japan, partly because the data behind it is published cleanly.

A lot of people spend a long time on this part and never actually go anywhere. They cross-reference the modern sheet against the old one, work out what the roads used to do, pull up registry records, and stop there.

the genres

In English, “urbex” is a single bag — buildings, mostly. In Japan the language splits it in ways that matter to how the work is done:

• haikyo — abandoned buildings. Hotels, hospitals, factories, mines, schools.
• haison — abandoned villages. Whole settlements that emptied out, usually because of dam construction, post-war forestry collapse, or peripheral depopulation.
• haidō — abandoned roads. Old prefectural routes, forestry railways, mountain passes that were bypassed by tunnels.
• haisen — abandoned rail lines.

Each has its own community, books, and reference sites. The flagship of haidō, yamaiga.com, has been online since 2001.

A big project there reads more like field reportage than a travel blog: Senzu Forest Railway Deep Section Operation runs 22 installments of fieldwork plus a 7-part return arc plus a desk-research preamble.

For abandoned villages, HEYANEKO’s archive holds prefectural lists with explicit inclusion criteria — Yamagata’s, for instance, starts at “abandoned on or after April 1959.”

None of this overlaps much with the buildings-and-photos urbex you’d recognize from English-language coverage; it’s closer to local history.

the rules everyone shares

The ethics, across all of this, collapse into one line:

Take nothing but photographs, leave nothing but footprints.

It comes from Jeff Chapman’s 2005 book Access All Areas. The Japanese scene shares it explicitly — same wording, same intent.

The unwritten parts are also fairly universal: don’t move things to compose a shot, don’t break in to something that isn’t already open, don’t go in big groups, don’t post the location, leave if you meet the owner.

There’s also a legal-by-permission route in both cultures that almost nobody talks about: you can ask.

In Japan, the MEXT closed-school project tracks abandoned schools, and many municipalities are actively trying to find uses for them — which makes the permission ask much less awkward than it sounds. In the US, EPA Brownfields publishes redevelopment-flagged industrial sites in the same spirit.

Both are minority routes in the community.

what the risk looks like

In Japan, unauthorized entry falls under Article 130 of the Penal Code — up to three years’ confinement, or a fine up to ¥100,000.

“It was abandoned” doesn’t really hold up; once a building has a lock or a no-entry sign, the law treats it as kanshu (kept), and entering counts. The owner doesn’t need to live next door.

There’s also a lighter parallel under the Minor Offences Act for genuinely unattended buildings, which carries detention or a small fine.

Cameras and motion sensors show up in more places than you’d guess, including ones that look completely forgotten. So does neighbor reporting in rural areas, where an unfamiliar car parked along a road for two hours is itself the signal.

The arrests that have actually happened in Japan cluster on one pattern: the video is the evidence. A few from recent years:

• two ghost-hunting youtubers at an abandoned skating rink
• three youtubers at an abandoned hotel (extortion alongside the entry)
• three more arrested on-site at another hotel during airsoft
• the operator of binbo-chunen tv in Fukuoka
• a man referred to prosecutors in 2016 for entering a tsunami-damaged school in Miyagi (under the Minor Offences Act rather than Article 130, since the school’s “kept” status after the disaster was less clear-cut)

In the US the same act splits along intent: trespassing on its own is a misdemeanor and usually settles in a fine, but if there’s a felonious purpose behind the entry it becomes burglary, which is a felony. The UK and continental Europe have their own variations, generally lighter than either.

what you carry

The list of gear for going into a building like this turns out to describe the building more than the visitor. You don’t pack for a ruin, you pack for the air and the floor and the wildlife around it.

A DS2-class dust mask (roughly N95-equivalent) is the standard, because anything built before the asbestos regulations may still have the old materials in the walls.

A headlight with a wide beam, because hands are for ladders and railings.

No open flame anywhere near a boiler or fuel-storage room — fumes from old oil tanks can sit in a basement for years, and a lighter is enough to set them off. That last one is from Hexplorer’s Haikyo Hazard, a 2001 page that’s still the closest thing to canonical safety reading in Japanese.

Not everything on that page survives verification. Hexplorer also argued that the nails inside ruins are 100% rusted and you should wear US Army surplus boots because sneakers can’t stop a puncture and safety shoes slip, and that a list of specific carcinogens are actively leaking from broken walls.

Both have failed cross-checking against more measured sources. The dust mask and the no-flame rule stayed.

Risks nobody has a single reliable Japanese-language source for: bears, wild boar, hornets, ticks (and the SFTS infection they can carry), mountain leeches, squatters or drug users in urban ruins, and what to do when your phone has no signal at all.

Hiking, forestry-safety, and occupational-health literature cover these better than urbex writing does.

the english side

The English-speaking scene has its own geography. Two big concentrations account for a lot of the photography you’d recognize.

The first is the US Rust Belt — Detroit (the Packard Plant, Michigan Central Station before its restoration), Pittsburgh and Cleveland and Buffalo, the corridor of steel and auto plants the 1970s–80s left behind. Abandoned America is the long-running documentation project there.

The second is Eastern Europe after the Cold War — Soviet bases left behind in East Germany and Poland, missile installations, the spomenik monuments of former Yugoslavia, the Bulgarian Communist Party headquarters at Buzludzha, and the Chernobyl exclusion zone (the only one with formal tour access).

Online, the long-standing hubs are r/urbanexploration and 28DaysLater (the British forum), with Atlas Obscura for tourist-facing coverage.

japan does the sharing differently

The interesting cultural difference isn’t the ethics — those are the same. It’s the information layer on top, and Japan’s looks different.

English-speaking urbex protects sites by hiding them. Locations don’t get posted. Access tends to move through trust and personal vouching; if you don’t know someone in the scene, you don’t get the address.

Japan layered something different on top. Haikyo Search Map is a public catalog of around 12,600 ruins with photos and access notes, about 3,000 of which have on-site photography by the operating team.

The house policy on the site is literally publish, but don’t visit. The phrase is kasou kanshou, “virtual viewing recommended.” The community optimized for being seen at home rather than visited in person.

But it’s not a single policy. Underneath the large public archive, individual explorers on Twitter, note, and YouTube still do the English-speaking thing — blur faces of buildings, name only the prefecture, rename places.

Two layers, opposite policies, both inside the same community. The public layer makes ruins consumable without travel; the personal layer protects the specific ones each person still goes to.

English-language coverage sometimes frames this through wabi-sabi or mono no aware — that the Japanese relationship to ruins is somehow more contemplative. I’d be careful with that framing.

It’s plausible-sounding, but the people I read in the scene don’t talk that way about what they do, and when researchers have tried to ground the claim it hasn’t tended to survive.

Closer to the truth is that Japan has a heavier enforcement environment, a denser archive, and very good satellite imagery, and the community grew up inside those constraints.

One small consequence: anything listed on the public archive has already been visited a lot. If part of what you want is the feeling of an undisturbed interior, public listings won’t give you that.

Untouched is either someone’s personal find — which they aren’t going to share — or one of the permission routes, which trades discovery for actually being allowed inside.

if you’ve never been

If this is your first time, the better move is to start from the public archive, not from your own discovery. Pick something listed on haikyo.info, read the entry and the user comments, and go to that one.

A few reasons:

• Listed sites have accumulated practical information about access, condition, and what’s dangerous inside them. You inherit that; with a fresh discovery, you don’t.
• You’ll see the visual cues and the geography from the answer side, which is how you learn to read them at the satellite layer later.
• Finding something nobody else has comes with a responsibility you don’t have to carry the first time out.

The trade-off is honest: a listed site has already been walked through by a lot of people, often roughly. The first few visits are about learning the shape of the hobby. Finding the untouched ones comes later.

closing

Maps and records can point you at a place; they can’t tell you what it is. The smell, the air a few rooms in, what a floor does under your weight — none of that comes through a photograph.

You have to be in the room. That’s why I go.

What stays with me from those rooms is hard to put into words, so I mostly don’t.
