If you have ever sat across from a Japanese real estate agent and watched them slide a stack of documents across the desk, you already know the feeling. The contract is thick, the kanji is dense, and somewhere in the process someone says the word hanko. For foreigners navigating the apartment contract Japan hanko situation for the first time, that moment can feel like a wall. It does not have to be.
Japan still relies on personal seals — hanko, or inkan — in a surprising number of everyday transactions. Signing your name is common in many countries, but in Japan, pressing a registered or personal seal into an ink pad and stamping a contract carries its own weight. For rental agreements especially, a hanko can appear at multiple points in the process: when you formally apply, when you sign the lease, and sometimes when you deal with the management company afterward.
This guide walks through exactly where seals show up in a typical Japan rental, what kind of seal is expected and when, how the guarantor and agency layer fits in, and what to do if you do not yet have a hanko. Whether you are a first-time resident moving into a monthly apartment or a long-term expat upgrading to a bigger place, the information here applies to you.
Where seals show up in rentals
Not every step in the rental process involves a hanko, but knowing which ones do saves you from being caught unprepared.
The most common points where a seal is requested:
- The formal rental application (moushikomi-sho): Many agencies still use paper applications, and some will ask for a hanko impression alongside your signature or in place of it.
- The lease agreement itself (chintai keiyaku-sho): This is the main event. The contract is typically two to five pages long, and you will be expected to affix your seal on each page or at designated signature points.
- The key handover receipt (kagi uketori-sho): When you collect your keys on move-in day, you often stamp a simple acknowledgement form.
- Requests from the management company (kanri-gaisha): If something needs to be updated during your tenancy — a parking addition, a change to your guarantor details — you may be asked to stamp a form.
A micro-scenario: Marta, a Brazilian engineer who moved to Osaka for work, assumed her written signature would be enough since she had signed contracts in three countries before. Her agency accepted her signature on the application but came back on lease day and asked for a hanko. She had not prepared one, which delayed her move-in by two days while the agency consulted with the landlord about alternatives.
Not every landlord or agency is inflexible — some now accept a signature or digital confirmation depending on the platform. But the default expectation in many traditional or privately managed buildings is still a physical seal.
Mitomein vs jitsuin for leases
Here is where foreigners often overcomplicate things, or go the opposite direction and underprepare. Japan has two broad categories of personal seal that are relevant to housing.
A mitomein is an informal personal seal. It is not registered with any government office. You can order one, receive it in a few days, and use it for daily paperwork. For most standard residential leases — especially in private apartments or through standard agencies — a mitomein is what you need. It does not need to match any official record; it just needs to be present.
A jitsuin is a registered seal. It has been officially recorded at your local city or ward office, and you can obtain a seal certificate (inkan shomeisho) to prove the registration. Jitsuin are typically required for high-stakes transactions: purchasing property, registering a vehicle, or in some cases, co-signing as a guarantor on someone else’s lease.
Common mistakes in this area:
- Assuming you need a jitsuin for a standard rental when a mitomein is almost always sufficient.
- Ordering a seal that is too large or uses a font style the agency finds hard to read — most seals used for rentals are 10.5mm to 12mm for individuals.
- Using a pre-made hanko purchased from a 100-yen shop or convenience store. These exist, but they carry generic characters. If your name is not a standard Japanese name, these will not match your registered documents anyway.
- Registering a jitsuin before confirming whether it is actually required. Registration is straightforward but takes a trip to city hall, and if your alien registration card (zairyu card) is not yet sorted, that adds another step.
A second micro-scenario: Tom, a British teacher who had been in Japan for three years on a series of short-term contracts, assumed his old hanko from a previous apartment would work for his new lease. The seal was fine — but it was in katakana, using his first name only. His new agency wanted his family name represented, which is common for formal contracts. A quick order for a new mitomein solved it before signing day.
Guarantors, agencies, and paperwork
Japan’s rental system has layers. Between you, the landlord, and the property, there is often a real estate agency (fudoosan), a management company, and a guarantor system (hoshounin or hoshougaisha). Each of these may generate their own paperwork, and each may have their own expectations about seals.
Individual guarantors — often a Japanese national willing to co-sign on your behalf — traditionally need a jitsuin and a seal certificate. This is one area where the formal registered seal genuinely matters, because the guarantor is taking on legal financial responsibility. If you are asking a Japanese colleague or employer to serve as your guarantor, expect them to need their own jitsuin-related documents.
Increasingly, however, Japan has moved toward corporate guarantee services (hoshougaisha). These companies charge a fee (usually around half a month’s rent) and act as your guarantor institutionally. Most corporate guarantee services do not require you to provide a jitsuin — they complete their own verification process and your mitomein is sufficient for your side of the contract.
The agency itself may also have its own forms: a brokerage agreement, a property condition report, and a fire insurance enrollment form are all standard. Each of these may have a stamp field. Keeping your hanko in your bag on any housing-related appointment day is simply good practice.

If you don’t have a hanko yet
This is the practical reality for many newly arrived foreigners: you have found a place, the agency wants to move fast, and you have not ordered a seal yet. Here is what to know.
Your options if a hanko is requested and you do not have one:
- Ask the agency whether a signature is accepted. Many newer platforms, digital-forward agencies, and some landlords dealing regularly with foreign tenants will accept a handwritten signature in lieu of a seal. This is increasingly common but still not universal.
- Request a short delay. If you need two to four days, most agencies will hold the unit while you wait for a hanko to arrive — especially if you have already paid a holding deposit or application fee.
- Order from a fast-turnaround service. Several hanko makers, including online services, offer two-to-five day delivery even for custom name seals in katakana, hiragana, or Roman letters.
What to order for rental purposes:
- A mitomein (non-registered personal seal) is sufficient for the vast majority of standard lease agreements.
- Standard material options include acrylic, wood, and composite materials — all are accepted for personal use in rental contexts.
- Size: 10.5mm is the most common for individual use. Some agencies or landlords have a size preference noted in their forms, but 10.5mm to 12mm covers virtually all cases.
- Name format: For foreigners, katakana is the most widely accepted rendering of your name for hanko purposes. Some people choose to use their legal name in Roman letters, which is also possible, though less traditional.
A third micro-scenario: Yusuf, a Rwandan researcher who arrived in Tokyo on a short-notice transfer, had exactly one week between arriving in Japan and needing to sign a lease for a sharehouse near his university. He ordered a katakana mitomein online within 48 hours of landing, received it in three days, and signed his contract without any delay. The seal cost him less than 3,000 yen and has since been used for his bank account opening and workplace onboarding forms.
One practical checklist before your lease signing day:
- Confirm with your agency whether a hanko or signature is required.
- If a hanko is needed, confirm whether mitomein or jitsuin is expected (mitomein is almost always sufficient for the tenant).
- Order your hanko at least five business days before your signing appointment.
- Bring your hanko, your zairyu card, and any documents the agency has requested.
- Keep your hanko in a dedicated case — losing it before the contract is signed is a stressful but surprisingly common issue.
FAQ
Can I use my signature instead of a hanko for a Japan rental? Sometimes, yes. It depends on the agency, the landlord, and the type of property. Newer agencies and properties managed through digital platforms are more flexible. Traditional landlords and older management companies often still expect a physical seal. If you are unsure, ask directly before your signing appointment.
Does my hanko need to be registered for a standard lease? No. For most residential leases as a tenant, an unregistered mitomein is sufficient. Jitsuin registration is more commonly required if you are acting as a guarantor or purchasing property.
What name should my hanko say? This varies by institution and landlord. Some contracts use your family name only; others use your full name. Check your lease documents and ask your agency what format they expect before ordering. Katakana is widely accepted for foreign names.
Can I use a hanko I bought at a convenience store? Technically yes, if the characters match your registered name. For most foreign residents, pre-made hanko sold in stores carry Japanese surname characters and will not match your name. A custom-ordered seal is a better investment.
How long does it take to get a hanko? Custom hanko from online services commonly ship within two to five business days. Some offer express options. Physical hanko shops (hanko-ya) in most cities can produce a basic seal same-day or next-day.
Do I need a different hanko for banking and housing? You can commonly use the same mitomein for both. A standard 10.5mm personal seal works for both residential leases and basic bank account openings at many major institutions, though requirements vary by institution.
