Under a rental lease agreement, you are required to notify your landlord or property management in writing within a "notice period for lease termination." This notice period is specified in the special conditions section of your lease, and is typically either one month (the default under civil law) or two months (commonly set by special agreement).

A thorough explanation of the move-out inspection (interior check) process when leaving a rental property. A real estate expert explains everything from pre-move preparation to checklist points on the day, judging appropriate restoration costs, negotiation tactics against unfair charges, and how to handle requests for signatures.
The main financial risks that arise when you submit notice late (or forget to submit it) are as follows:
Additional rent: If the notice period is one month and you submit notice only three weeks before moving out, you will be charged rent for the period from your notice until one month has elapsed (in this example, approximately one week). Even if you want to move out earlier, rent continues to accrue until the full notice period has passed.
Early termination penalties: If your lease specifies a "minimum occupancy period" (e.g., you cannot terminate within two years of moving in) or "early termination penalties" (e.g., if you move out within one year, you must pay a penalty equal to 1–2 months' rent), these penalties may be charged if you fail to meet the conditions. These are separate from and in addition to any extra rent resulting from late notice.
Overlapping rent payments: If you cannot move out earlier, you may face "double rent" if your new lease begins before you've officially vacated your current apartment, meaning you pay rent on both properties simultaneously.
Step 1: Check your lease for the required notice period
Review the "Termination and Lease End" section of your lease agreement to understand how many months' notice is required and whether there are conditions under which the period can be shortened. Even if two months' notice is required, some properties have special conditions allowing negotiation in cases of special circumstances (such as a sudden job transfer or medical emergency).
Step 2: Contact property management immediately
Once you've decided to move, submit your termination request in writing (via email or physical letter) rather than by phone. While a phone call communicates your intention, the date the management company receives your written notice becomes the official "notice start date." Written communication with a timestamp is crucial—email is particularly effective because it includes a timestamp.
Step 3: Explain your situation honestly and ask for assistance
Provide specific details about why you need to move urgently—such as a sudden job transfer, health concerns, or a confirmed move-in date for your new place. Some property management companies are willing to negotiate a shortened or waived notice period if you provide legitimate reasons.
Step 4: Negotiate the additional rent
If your notice was one week late, you may be able to negotiate the one week's additional rent by proposing to set your official move-out date (and key return date) within the required notice period, with no rent accruing after that. If the property management company is eager to find a new tenant quickly, there may be room for negotiation.
When your current lease's move-out date and your new lease's move-in date overlap, causing you to pay rent on both properties, here are key points to minimize your financial loss:
Optimize your key return timing: While the lease end date (when rent stops) may come first contractually, you may physically be able to return the keys the day after the official move-out date. Since rent is typically calculated on a prorated daily basis, even moving up your official move-out date by a single day can reduce your costs.
Check for housing allowances or subsidies: If your move is due to a job transfer, your employer's housing allowance program may include coverage for overlapping rent. Check with your HR department.
Adjust your new lease's start date: Your new apartment's rent begins on the day you receive the keys (move-in date). You may be able to reduce the overlap period by delaying key pickup. Schedule your viewings and signing earlier, then ask to adjust only the move-in date.
Your notice to vacate must include the following four pieces of information:
Submit your notice in writing (by mail or email) using a method that provides proof of delivery (certified mail or email read receipt). Some property management companies have their own standard termination notice form, so check with them beforehand.
Under Article 617 of Japan's Civil Code, the default notice period for lease termination is three months. However, under the Building Lease Law and standard practice for residential properties, the notice period is typically one month.
If your lease specifies a two-month notice period as a special condition, this special condition is legally valid and you must follow it. The argument that "the special condition is invalid, so one month is sufficient" misrepresents the relationship between contract terms and law and will not be accepted.
However, if the special condition is unreasonably unfavorable to you as a tenant (for example, requiring six months' notice), it may be deemed invalid under the Consumer Contract Law. If you question the reasonableness of a special condition, we recommend consulting a consumer affairs center or attorney.
To prevent the situation of forgetting to submit notice, it's helpful to prepare with your eventual move-out in mind from the moment you move in.
Set reminders on your phone: When you move in, add "notice deadline" to your calendar. Once you decide roughly when you might want to move, calculate backwards and set the deadline right away. Build a habit of registering the deadline immediately.
Save your lease digitally: Photograph the pages of your lease showing the notice period and store them in the cloud. Having easy access while apartment hunting prevents the mistake of committing to a move-out date without verifying the required notice period.
Late notice is usually caused by insufficient advance planning and procrastination. The best prevention is to contact your property management company and prepare written notice on the same day you decide to move out.
