Six weeks before a lease renewal date, I open a spreadsheet I have kept updated for more than 15 years and ask myself one blunt question: do I want this person living in my building for another 24 months? Across my 9 rental units, I have chosen not to renew exactly 4 tenants over that span, and each time the decision felt harder than it should have, because a difficult tenant is rarely difficult in a single, obvious way.
Most landlords either renew everyone automatically to avoid the paperwork, or they let one bad month scare them into ending a lease they will end up regretting. I try to sit in the middle, using a repeatable decision process instead of a gut reaction made under deadline pressure.

In Japan, a standard fixed-term or auto-renewing lease usually gives you around a 60-day window before expiration to formally notify a tenant of non-renewal, though the exact figure varies by contract wording and by prefecture. I personally start my review 90 days out, because that gives me time to pull a full 12 months of payment history, check the building’s shared complaint log, and walk the unit myself if I have any doubt about its condition. Waiting until the last 30 days almost guarantees a rushed, emotional decision, and it leaves no room to fix a paperwork mistake if my contract template is out of date.

Non-renewal is never free, and treating it as a clean fix ignores the numbers. On my properties, a full turnover between tenants runs somewhere between 180,000 and 340,000 yen once I account for professional cleaning, minor repainting, key and lock cylinder replacement, and 2 to 3 weeks of vacancy while I re-list the unit. That is real money, and it is the figure that keeps me from acting on frustration alone. If a tenant pays rent 10 days late twice in a year but is otherwise quiet and easy on the unit, the math usually favors a firm written warning over non-renewal. If that same tenant is also damaging fixtures or generating repeated complaints from neighbors, the vacancy cost stops looking so large by comparison, and I start leaning the other direction.
Red Flags I Actually Track
Over the years I narrowed my criteria down to a short, specific list, because vague dissatisfaction is not a fair reason to end someone’s housing. The pattern matters far more than any single incident, and I try to be honest with myself about the difference.
- Rent paid more than 10 days late on 3 or more occasions in the past 12 months
- Two or more written noise or nuisance complaints from other residents in the building
- Unauthorized alterations to the unit, such as removed fixtures or an undisclosed pet
- Refusal to allow a scheduled inspection or repair visit after 2 reasonable notice attempts
- Visible deterioration of the unit beyond normal wear during a routine walk-through
If a tenant hits two or more of these items within a single lease term, I lean toward non-renewal. One item alone, especially the late-payment one, usually earns a direct conversation first rather than an automatic decision.
The Conversation Before the Decision

Property Inspection Forms & Checklists

I never skip this step, even when I am fairly confident I will not renew. About 4 months before the lease ends, I call or meet the tenant in person and lay out exactly what I have observed, using dates and yen amounts rather than impressions or general complaints. Roughly half the time, this single conversation resolves the issue, because the tenant genuinely did not realize how the pattern looked from my side of the ledger. The other half of the time, it confirms that the relationship is not going to improve, and it gives the tenant fair notice, often a full 4 months, to start apartment hunting instead of being blindsided by a non-renewal letter with only 60 days left on the clock.
My Renewal Checklist
Before I sign or decline any renewal, I run through the same short checklist on every one of my 9 units, with no exceptions, because consistency protects me if a decision is ever questioned by the tenant or a mediator.
- Pull the full 12-month rent ledger and count every late payment
- Review the building complaint log for the same 12-month period
- Walk the unit myself or review recent maintenance request photos
- Calculate the realistic turnover cost for that specific unit
- Have the direct conversation at least 90 days before expiration
- Put the final decision in writing, even when the answer is a simple renewal
That last item matters more than most new landlords expect. I learned this the hard way after a verbal renewal turned into a dispute over the rent increase amount, and a one-page written confirmation now prevents almost every disagreement I used to run into at renewal time. It takes about 15 minutes to draft and it has saved me far more than that in avoided arguments.
When I Choose to Renew Anyway
Not every tenant who feels difficult gets shown the door. One of my longest-tenured renters has been with me for 8 years and pays late almost every single month, yet the rent always arrives within the grace period, the unit is spotless at every inspection, and there has never been a single complaint from a neighbor. In that case, a habitually late payment is an inconvenience, not a risk to the property or to the other residents, so I renew every time without hesitation. Difficult and risky are not the same thing, and mixing them up is the most common mistake I see other small landlords make, usually because they are reacting to annoyance rather than actual financial or structural risk.
That is the process I run across all 9 of my properties, and it has kept my average vacancy period under 3 weeks even in years when I had to let a tenant go.
