The akiya inspection checklist: 17 things to check before you buy

The price is the bait. A house for ¥3,000,000 looks like a bargain right up until the roof, the foundation, or a line in the property register turns it into a money pit you can't sell.

The viewing is where you catch that — or miss it. You usually get one walk-through before you decide, often with no inspector, sometimes in a house no one has maintained for years. So go in with an akiya inspection checklist: knowing exactly what to look at, in what order, and which findings mean walk away.

Here are the 17, grouped from the expensive structural problems down to the legal ones that quietly kill a deal. Want them as a sheet you can carry into the viewing? Grab the [free printable akiya viewing checklist → /free-download] and tick them off on site.

The bones: structure and roof

This is where the real money hides. Cosmetic problems are cheap. Structural ones aren't.

1. The foundation

Look for cracks wider than a coin, sections that have sunk, or a building that visibly leans. Older rural homes often sit on stone or shallow footings with no rebar. A failing foundation is one of the most expensive things to fix — and one of the few that can make a house not worth saving.

2. The roof

Ask the age. A Japanese tile (瓦, kawara) roof can last decades, but the underlayment beneath it doesn't. Water stains on the ceilings, sagging ridgelines, or daylight in the attic mean the roof is already failing. A full reroof is one of the largest single line items in any akiya renovation.

3. Termites (白蟻, shiroari)

Japan's climate is hard on wood, and termites are common. Tap the lower pillars and sills — hollow sounds, crumbling wood, or little mud tubes near the base are warnings. Damage to load-bearing timber is a structural problem, not a pest problem.

4. Pillars and beams

Sight down the main posts. Do they lean? Do the beams sag in the middle? A house that has racked or settled out of square has moved, and finding out why it moved is the question that decides whether it's fixable.

5. The floors

Walk every room. Springy, sloping, or bouncing floors point to rot or failing joists underneath — often from long-term damp. A floor that dips toward one corner is telling you the structure below it is giving way.

Water, waste, and power

The systems that make a house livable, and that cost a fortune to replace.

6. Plumbing and water pressure

Run the taps. Weak pressure, brown water, or knocking pipes suggest old, corroded plumbing. In a house that's sat empty, pipes may have frozen and split. Assume nothing works until you've seen it run.

7. Septic vs. sewer (浄化槽, jōkasō)

Many rural homes aren't on a public sewer — they use a jōkasō, an on-site septic treatment tank that needs regular servicing and eventually replacement. Ask which system the house has, when the tank was last maintained, and whether a public sewer is even available. This surprises a lot of foreign buyers.

8. Electrical capacity

Old rural homes were wired for a different era. Check the amperage (look at the breaker panel) and the state of the wiring. If you plan to run modern appliances, air conditioning, or an induction stove, the supply may need upgrading — and so might the contract with the power company.

9. The bath and water heater

The bathroom is often the most dated and most expensive room to redo. Check the water heater's age and whether it even runs. A traditional unit-bath swap is a known, sizable cost.

Damp, mold, and cold

The slow problems that decide whether you actually want to live there.

10. The smell

Walk in and breathe. A musty, earthy smell means moisture — and moisture is behind most of the rot, mold, and structural decay on this list. Trust your nose before your eyes.

11. Insulation

Many older Japanese houses have little or none. That means cold winters, hot summers, and condensation that feeds mold. Retrofitting insulation is doable but adds up, and it's invisible until you're living through February.

12. Windows and drafts

Single-pane glass and gaps around old wooden frames leak heat and let damp in. Feel for drafts. It's not a dealbreaker, but it's a cost, and it compounds the insulation problem.

The silent dealbreakers: land and legal

These don't show up in photos and won't announce themselves at the viewing. They're also the ones most likely to make a cheap house worthless — so check every one.

13. Can you even rebuild on it? (再建築不可, saiken fuka)

This is the big one. Under Japan's Building Standards Act, a plot generally must front a designated road by at least two meters to be buildable. Many old rural and back-alley properties don't qualify — they're marked 再建築不可, "cannot be rebuilt." You can repair the existing house, but if it burns down or you demolish it, you can never build again. It tanks the value and your exit. Ask directly, in writing.

14. Road access and boundaries

Related, and just as quiet. Is there a legal right of way to the property? Where do the boundaries actually run? Many rural plots have never had a modern survey (地積測量図), and a boundary dispute with a neighbor is a problem you inherit.

15. Who actually owns it

Pull the property register (登記簿, tōkibo). Confirm the registered owner is the person selling, and that there are no liens or mortgages attached. Inherited akiya are often still registered to a grandparent who died years ago, with the title split among heirs who haven't all agreed to sell. That can stall or sink a purchase.

16. Unregistered additions (未登記, mitōki)

Compare the building on the register to the building in front of you. Extra rooms, an extension, or an outbuilding that isn't on the register (未登記) can mean tax problems, financing problems, and legal headaches that become yours at closing.

17. The hazard maps

Before you fall for the setting, check the municipal hazard maps (ハザードマップ) for flood, landslide, and earthquake risk. Rural and riverside akiya can sit in zones that affect insurance, safety, and resale. It's a five-minute check that can end a deal cleanly.

The akiya inspection checklist: when to walk away

Not every problem is fatal. Damp, dated baths, weak wiring — those are budget items. But a few findings should end the viewing:

• 再建築不可 — you can't rebuild, which caps the value and traps you.

• A foundation that has failed, not just cracked.

• Title that isn't clean — unclear ownership, unresolved inheritance, or liens.

• A roof and structure both gone, where you're rebuilding the house anyway.

A cheap house with one of these isn't a bargain. It's a liability with a low entry price.

After the checklist

Catching the problems is half the job. The other half is knowing what they'll cost you and how the purchase actually works.

Before you fall for a listing, run the real number — the price is never the price once taxes and fees are on it: [the cost calculator → /cost-calculator]. And carry the [free printable viewing checklist → /free-download] into every viewing so nothing on this list slips past.

When you're past viewing and ready to buy, [The Akiya Guide → /the-akiya-guide] is the full process — reading the listing, the due diligence in depth, the offer, the paperwork, the payment. The 17 above are the dealbreakers to spot in the room; the guide is everything that happens after you find one worth pursuing. $199, once.

The cheap house is real. So are the ways it can cost you. Check before you commit, not after.
