What shako shomei actually is
Shako shomei (車庫証明), formally the jidosha hokan basho shomeisho (自動車保管場所証明書), is a certificate issued by your local police station confirming that you have a legal, dedicated parking space for a vehicle. It is not optional paperwork you can skip — for most cars, you cannot complete vehicle registration at the transport bureau (陸運局, rikuunkyoku) without it. No certificate, no registration, no license plates.
The logic behind the system is simple: Japan wants to prevent cars being parked on public streets overnight, so before you're allowed to own one, you have to prove you have somewhere off-street to put it. The police aren't just rubber-stamping this — they can and sometimes do send an officer to physically check that the space exists and is available.
If you're still deciding whether you even need a car in Japan, it's worth reading our guide on whether you need a car in Japan before you get into the parking-certificate weeds.
Do you need one for a kei car too?
This is where people get confused. For regular-sized cars (普通車, futsuusha), shako shomei is required almost everywhere in Japan. For kei cars (軽自動車), the rule is narrower: the certificate is only required in designated urban and densely populated areas — most major cities and their surrounding suburbs. In many rural areas and small towns, kei car owners can skip the police certificate entirely and instead just submit a simpler self-declared parking notification directly with the vehicle registration.
You cannot assume either way — check with your local police station or ask the dealer/shaken shop handling your registration, since the boundary lines for "designated area" don't always match what you'd expect. If you're weighing a kei car against a compact car in general, see our kei car vs. compact car cost comparison for the bigger financial picture.
The eligibility rules for your parking space
Not just any spot qualifies. The space you list has to satisfy three conditions:
- Distance: it must be within roughly 2 km (by road, not straight-line) of the address on your residence certificate (juminhyo). If your apartment doesn't come with parking and you rent a space elsewhere, it has to fall inside this radius.
- Size: the space must be large enough to fully contain the vehicle, with the car able to enter and exit under its own power. Oversized vehicles won't qualify for an undersized spot, even if it "mostly fits."
- Right of use: you must have a legitimate right to use the space — either because you own the land, or because you rent it with the owner's or management company's explicit permission. You cannot list a space you don't actually have permission to use, even informally (e.g., an empty lot near your building).
The documents you'll need
The application packet has three core pieces, and this is where foreign residents most often get tripped up because the forms are entirely in Japanese and the requirements vary slightly by prefecture.
1. Application form — 自動車保管場所証明申請書 (jidosha hokan basho shomei shinseisho)
This is the main application, usually submitted along with a duplicate/carbon copy and the 標章交付申請書 (sticker issuance request) that gets processed at the same time. It asks for your details, the vehicle details (you'll often need the chassis number from the dealer), and the parking location.
2. Location and layout map — 保管場所の所在図・配置図 (hokan basho no shozaizu / haichizu)
Two simple diagrams: one showing where the parking space is relative to your home address (to prove the 2 km rule), and one showing the layout of the parking lot itself with the dimensions of your specific space marked. These do not need to be professionally drafted — a clear hand-drawn sketch with measurements is standard and accepted. Many police stations even hand out a blank template you can fill in on the spot.
3. Proof of the right to use the space
This is the document that causes the most delays, so pay attention here:
- If you own the land the car will be parked on, you self-certify with a hokan basho shiyo kengen soumeisho / jininsho (保管場所使用権原疎明書面・自認書) — you're simply declaring the space is yours.
- If you rent the space (the far more common situation for foreign residents), you need a hokan basho shiyo shodaku shomeisho (保管場所使用承諾証明書) — a consent form that must be signed and stamped by the landlord, parking lot owner, or the management company that administers the lot.
Where to apply
You submit the application at the police station (警察署, keisatsusho) that has jurisdiction over the parking space's location — not the police station near your home address, if the two differ. This trips people up when their parking spot is in a different ward or city than their residence. Look up jurisdiction by the parking lot's address, not yours.
Fees and timeline
Expect to pay a modest fee in the form of 証紙 (shoshi) revenue stamps purchased at or near the police station — typically in the low thousands of yen total, covering both the certificate and the sticker, with the exact amount set by each prefecture. This is separate from any registration or dealer fees.
Once submitted, processing typically takes about 3 to 7 business days, though it varies by prefecture and season (expect it to be slower during the March registration rush). During this window, the police may visit the parking location to confirm it matches your application — you don't need to be present, but the space needs to actually be usable and match your diagram. When it's approved, you go back to the station to collect the shako shomei certificate itself plus a small 標章 (hyosho) sticker that typically gets displayed on the car's rear window.
Practical tips for foreign residents
- Start this before you finalize the car purchase. Dealers can't complete registration without the certificate, and the whole chain — parking arrangement, consent form, police application, wait time — can easily take one to two weeks. Factor that into your purchase timeline.
- If you're renting, chase the consent form first. It depends on a third party (landlord or management company) responding, which is the part most outside your control.
- Don't overthink the maps. Simple, accurate, hand-drawn diagrams with measurements are completely normal and accepted — you don't need software or professional drafting.
- Confirm the kei car rule locally rather than assuming — it can save you the entire process if you're outside a designated area.
- Bring your residence card and juminhyo when you visit the station, since forms will ask for official address details that need to match your registration records exactly.
