Can You Sign If You Can't Read the Japanese Contract? Rental Disclosures and Language Support
Written by：SUMIMOTO Inc.Editorial Policy
Sitting in front of a stack of Japanese documents and signing because "everyone does" is a worry foreign renters often describe.
This article explains the role of the pre-contract explanation, how to use translations and interpreters, and what to check before you sign. Everything here is a general guide and varies by property and contract.
What is the pre-contract explanation, and is it separate from the lease?
When a licensed real estate agent brokers a rental, a qualified staff member (takken-shi) generally explains the key terms from a written disclosure document before the contract is concluded. It is a separate document from the lease itself and tells you what you should know before committing.
Once the contract is concluded, a document stating its terms is handed over. So you effectively get two chances to check the terms: at the explanation stage and at the lease-signing stage.
Numbers to keep in mind
- Main papers around signing
- 2documents
- Common term for ordinary leases
- 2years
Disclosure document and contract document
Depends on the contract
Can you use a foreign-language explanation or translation?
The explanation is assumed to be given in Japanese, but a growing number of agencies prepare translated documents, bring an interpreter, or offer an online explanation. Support differs by company, so ask early, around your viewing.
Note that a translation is usually a reading aid; many contracts treat the Japanese original as the authoritative text. If a translation and the original seem to differ, point to the passage and ask the agent.
Main items to review before signing
| Item | Where to look | What to check |
|---|---|---|
| Rent, common fees, deposits | Disclosure document and contract | The monthly total and a breakdown of move-in costs |
| Term and renewal | Contract | Whether it renews, and whether a renewal fee applies and how much |
| Notice for termination | Contract | How many months ahead, and to whom, you must give notice |
| Prohibitions and special clauses | Contract and special-terms section | Pets, instruments, subletting, move-out cleaning fees, etc. |
| Guarantor company, emergency contact | Disclosure document | The guarantee fee and any cost at renewal |
How far are special clauses and prohibitions valid?
Besides standard terms, a contract may include individually agreed "special clauses." These are generally valid if both parties agree, but a clause that one-sidedly disadvantages the tenant may be held invalid in a dispute.

What should you do before signing?
Many people feel they must decide on the spot, but you need not proceed while unconvinced. Write down your questions and take time to confirm them one by one.
Common gaps and fixes
✕Read only the translation and never looked at the special-terms section of the Japanese contract.
→Always check special terms and prohibitions in the Japanese original, and ask the agent about anything unclear.
✕Conditions promised verbally (leaving furniture, no cleaning fee) were not in the document.
→Have verbal promises put in writing in the contract or a side memo.
✕Did not check the renewal fee or termination notice and faced unexpected costs at move-out.
→Go over the term, renewal fee and termination notice before signing.

FAQ
- Q. Can I rent without speaking Japanese?
- A. It is easier with agencies that offer foreign-language support or translated documents. The guarantor screening and contact requirements still need separate checking.
- Q. What if the translation differs from the Japanese original?
- A. Many contracts state that the Japanese version prevails. If you notice a difference, ask the agent before signing.
- Q. Can the explanation be given online?
- A. Online explanations are reportedly available in some cases. Ask the agency in advance how it can be given.
