How To Check If A Japanese Property Is In A Land Use Monitoring Area

What the two zone designations actually cover

The law lets the national government designate 注視区域 within roughly 1,000 meters of an "important facility" — Self-Defense Force facilities; installations used under the Japan-US security treaty and the Status of Forces Agreement (US military bases); Japan Coast Guard facilities; nuclear power plants and other critical infrastructure — and within the inhabited areas of designated 国境離島等 (remote border islands, including islands like Tsushima and Yonaguni that have drawn attention over foreign land purchases). Where a facility's function is especially important, or particularly easy to disrupt and hard to replace with another facility, the area around it is designated 特別注視区域 instead — a stricter tier with its own notification duty, described below. Designations are added in periodic rounds; by the most recent rounds reported, several hundred zones across roughly thirty prefectures had been designated, and the list keeps expanding, so a parcel that was clear at an earlier round is not guaranteed to stay that way.

The pre-notification duty inside Special Areas of Attention

Inside a 特別注視区域, both the buyer and the seller must submit an advance notification to the national government (formally, to the Prime Minister) before concluding a contract to transfer or create ownership rights over land or a building at or above 200 square meters — measured per parcel for land, and per building (combined floor area, including any attached structures) for a building. The notification covers the parties' identity and address and the intended use of the land, and as of a 2026 update to the notification form, the parties' nationality as well. This 200㎡, per-parcel/per-building threshold and the advance-notification duty apply only inside a Special Area of Attention; plain Areas of Attention do not carry this same pre-transaction filing requirement.

The separate national-security notification under the Land Use Planning Act

Do not confuse this with 国土利用計画法 (the National Land Use Planning Act), a longer-standing, unrelated law that requires the buyer alone to notify the local government after signing a contract, once the land involved passes its own, larger size thresholds. The two regimes have different triggers, different timing (before signing vs. after), and different filing parties, and practitioners note this is a common point of confusion — a property can be subject to one, both, or neither, depending on its size and location.

What happens after a designation, and the penalties involved

Beyond the notification duty, the government can survey land use inside either type of zone and, if it finds the land or building is being used in a way that impairs the facility's function, issue a recommendation — and, if unheeded, an order — to stop that use. Two separate penalty regimes apply. Signing a contract in a Special Area of Attention without submitting the required notification, submitting a false notification, or failing to file within roughly two weeks of the contract date can carry a prison term of up to six months or a fine of up to ¥1,000,000. Separately, ignoring a cessation order after a land-use survey can carry a prison term of up to two years or a fine of up to ¥2,000,000, or both. Neither regime is a nationality-based ban — the law applies equally to Japanese nationals and foreigners — but the notification form's nationality field means foreign buyers should expect this to surface as a distinct step wherever it applies, on top of the usual purchase paperwork.

Here is a practical way to check before you get attached to a listing:

1. Locate the lot number. Confirm the parcel's lot number (地番, chiban), since you will want it both to search the government's own map tool accurately and, later, to describe the property correctly on a notification form if one turns out to be required. Our lot number search and the guide to finding a lot number cover this step.
2. Search the official web map. The Cabinet Office publishes a free "Important Land Web Map" (重要土地ウェブ地図), reachable from the "区域の指定について" (designated areas) page on cao.go.jp, which lets you search by address and see whether a location falls inside a 注視区域 or 特別注視区域, and which tier applies.
3. If it falls inside a zone, check the size against the 200㎡ threshold. The threshold applies only in Special Areas of Attention, and is measured per parcel of land or per building (combined floor area) — a large lot that has been subdivided on the registry, for example, is assessed parcel by parcel, not by the combined area of the listing.
4. Confirm with the Cabinet Office directly, or with a judicial or administrative scrivener, if you are close to a boundary or unsure which tier applies. The Cabinet Office runs a call center for exactly this kind of question, and a scrivener handling the closing can confirm the current designation before you sign.
5. If a notification is required, build the roughly two-week filing window into your closing timeline. Both buyer and seller must file separately, by mail or through the government's e-Gov online system, and the notification requires the parties' identity, address, nationality, and intended use of the property.
6. Re-check close to your signing date, not just when you first found the listing. Designations are periodically expanded, and a parcel that was outside any zone when you started looking is not guaranteed to still be outside one months later.

The most common mistake is assuming a clean listing address, with no mention of a base or facility nearby, rules this out — the roughly 1,000-meter designation radius and the border-island designations are not always obvious from a map at a glance, and the government's own web map is the only way to check reliably. The second is confusing this notification with the unrelated National Land Use Planning Act filing, which has a different trigger, timing, and filing party and does not substitute for checking this one.

What the registration record can and cannot tell you here:

• What it shows reliably: ownership, mortgages, and the registered description of the land or building — the same as for any other property.
• What it does not show: whether the parcel sits inside a designated Area of Attention or Special Area of Attention. This is a Cabinet Office national-security designation, not a fact recorded in the registry, so a completely clean registration record says nothing about whether a notification duty applies.
• How to order the record: On Japan Property Research, use the free lot number lookup to identify the parcel, then order the land registration record for ¥1,500. If the property includes a house, order the building registration record as well, since land and buildings are registered separately. Both are delivered by email and saved to your account — useful not only for standard due diligence, but for getting the exact parcel and floor-area figures right if you do need to complete a pre-notification. Neither the registration record nor the free lookup tool substitutes for the Cabinet Office web map check above.

None of this makes a designated-zone property automatically off-limits — the vast majority of transactions there proceed normally once the paperwork is filed on time. But it adds a step, and a deadline, that a buyer researching a bargain listing near a base or on a remote island should plan for rather than discover at closing. Our Japan property due diligence checklist covers where this check fits alongside ownership, road frontage, and zoning review.

FAQ

What is Japan's Land Use Monitoring Act? It is the common shorthand for 重要土地等調査法, officially the Act on the Review and Regulation of the Use of Real Estate Surrounding Important Facilities and on Remote Territorial Islands, in force since September 20, 2022. It lets the national government designate zones around defense-related facilities and border islands, monitor land use inside them, and — in the stricter "Special Area of Attention" tier — require advance notification before a land or building sale.

Does this law ban foreigners from buying property in Japan? No. It applies equally to Japanese nationals and foreigners, and it does not prohibit a sale — it requires notification (in Special Areas of Attention) and permits government monitoring and, in serious cases, a use-cessation order. The notification form does ask for the buyer's and seller's nationality, so a foreign buyer should expect that disclosure wherever the requirement applies, but qualifying and closing the purchase works the same way it does for a Japanese buyer.

How do I find out if a specific property is in a designated zone? Use the Cabinet Office's free Important Land Web Map, searchable by address from the designated-areas page on cao.go.jp. It is the only reliable way to check — the roughly 1,000-meter radius around a facility, and the border-island designations, are not something you can infer from a standard map or from the property listing itself.

What is the difference between an Area of Attention and a Special Area of Attention? Both let the government monitor land use and issue a use-cessation recommendation or order if it finds the land is being used to impair a facility's function. Only a Special Area of Attention adds the advance-notification duty for land and building transactions at or above 200 square meters.

Is this the same as the National Land Use Planning Act notification? No, though they are easy to confuse. The National Land Use Planning Act (国土利用計画法) requires only the buyer to notify the local government, after signing, once the land passes its own size thresholds — an unrelated, longer-standing regime. This law requires both parties to notify the national government before signing, inside a Special Area of Attention, at a much lower 200㎡ threshold. A property can be subject to either, both, or neither.

Does the property registration record show any of this? No. The registration record covers ownership, mortgages, and the registered description of the land or building. The zone designations are a Cabinet Office national-security designation, not something recorded in the registry.

A note on scope: this session's network access could not reach e-Gov's own statute-text pages or the Cabinet Office's PDF leaflets directly to quote article numbers verbatim, so the facts above are drawn from the Cabinet Office's own web pages and notices (including as reproduced by prefectural and municipal governments) together with licensed-scrivener and industry secondary sources, cross-checked against each other rather than a single source. The count of designated zones and prefectures changes as new rounds are announced — always confirm the current designation for a specific parcel using the Cabinet Office's own web map rather than relying on a figure quoted here. The exact statutory article numbers for the notification duty and penalty provisions, and the precise wording of the roughly two-week cure period, should be confirmed against the current e-Gov text (elaws.e-gov.go.jp) or with a judicial scrivener (司法書士) or administrative scrivener (行政書士) before you rely on them for a specific transaction.
