Ending a cohabitation involves significant emotional and financial stress. Especially in situations where you must find a new place immediately, rushing can easily lead to poor decisions.

When ending cohabitation, the first thing to confirm is whose name the current rental lease is under.
If you are the contractor: You need to decide whether to cancel or have the other person take over the contract. If canceling, you must follow the cancellation notice period in the contract (generally 1–2 months notice). If this period passes, you will continue to have the obligation to pay rent.
If the other person is the contractor: If the other person handles the cancellation procedures, you only need to move out, but you must coordinate carefully with the other person about the timing of the cancellation notice and move-out date.
If the contract is under both names (joint guarantor): If one person is staying, the person remaining may need to undergo a new individual application and assessment. Consult with the property management company.
Security deposit refunds are issued to the lease contractor in principle. If you both contributed to the security deposit, it's important to discuss how to divide it before ending the cohabitation.
The typical timeline from deciding to end cohabitation to moving into a new place is as follows:
| Step | Estimated Timeline |
|---|---|
| Start apartment search | 0–3 days |
| Viewings and application | 3–7 days |
| Screening and contract signing | 7–14 days |
| Move-in date | 3+ days after contract |
Even if you're in a hurry, rushing to decide on a property often leads to regret. I recommend viewing at least 3–5 properties.
When searching for "move-in ready" properties, using search filters for immediate occupancy is helpful. If a property has vacant rooms and restoration to original condition work is complete, you may be able to move in 3–5 days after passing the screening.
There are several precautions when applying for a rental apartment right after ending cohabitation.
Income and Employment Verification: Since you'll be applying as a single person, the general screening standard is that your income alone is at least 3 times the monthly rent. If you were both working and relying on your partner's income, you may need to lower the rent.
Guarantor Company: Most rental properties require the use of a guarantor company. The screening is affected by length of employment and income, so it may be difficult if you've recently changed jobs.
Previous Address: The application form has a field for your previous address. It's no problem to write the cohabitation address, but the screener may ask about the circumstances. You can honestly answer "due to ending cohabitation" with no issues.
Ending a cohabitation often happens at unexpected times, and securing initial costs can be difficult. You can reduce costs with these methods:
Free-Rent Properties: By choosing a "free rent" property where the first 1–2 months of rent are free, you can significantly reduce the initial month's burden.
Zero Key Money Properties: Since key money is a non-refundable fee, choosing properties with zero key money saves on initial costs.
Negotiating Moving Costs: Avoiding busy seasons (March and September) tends to reduce moving costs. Also, by getting quotes from multiple moving companies, you can reduce expenses.
Disposing of Unnecessary Items: When sorting through furniture and appliances related to the cohabitation split, you can offset moving expenses by selling unnecessary items at secondhand shops or through resale apps.
After moving to your new place, don't forget to complete these administrative procedures.
Changing Resident Registration: You are required to file a change of address form at your new address within 14 days of moving (Resident Registration Law). File the moving-out notification at your previous municipality's office.
Mail Forwarding: Through Japan Post's "e-tenkyo" or by submitting a forwarding request at a post office, you can have mail sent to your old address forwarded to your new address free of charge for one year.
Updating Various Registered Addresses: Don't forget to change your address for bank accounts, credit cards, mobile phone contracts, driver's licenses, and other services.
Apartment hunting after ending a cohabitation is often work done while emotionally affected. Since making important decisions (choosing a property) in a rush often leads to regret, if possible, I recommend bringing a trusted friend or family member along.
Additionally, by simulating your living expenses as a single person (food, utilities, communications, household supplies, etc.) in advance, you can mitigate economic shock after moving in. When transitioning from two-person to single-person living, monthly living expenses often increase, so it's safe to keep rent at 25–30% of your income.
Apartment hunting after ending a cohabitation is work that carries significant emotional, time, and financial burden. It's important to first confirm whose name the current rental contract is under and the cancellation procedures, then select properties with awareness of the single-person screening criteria. While keeping initial costs down by using free-rent and zero key money properties, don't forget to complete administrative procedures and start your new life.
