Two years ago I raised the rent on one of my units by 8,000 yen a month and the tenant renewed without a single complaint. Six months later I raised another unit by only 3,000 yen and the tenant moved out within 30 days. The difference wasn’t the amount. It was how I brought it up. After managing 9 rental properties myself for over 15 years, I’ve learned that a rent increase is a conversation you can win or lose before you even mention a number.
Losing a reliable tenant costs far more than the increase you’re chasing. A typical turnover on my properties runs 120,000 to 180,000 yen in cleaning, minor repairs, and re-listing fees, plus a vacancy that can stretch past 45 days. If you handle the conversation well, you rarely have to eat that cost.
Why Rent Increases Backfire When You Do It Wrong

Most failed rent increases fail for the same three reasons: the tenant feels ambushed, the increase feels arbitrary, and there’s no room left for them to respond. A letter that simply states a new figure with 14 days notice reads like a threat, even if that’s not the intent. I’ve found that tenants who’ve paid on time for 2 or 3 years straight react badly to being treated like a stranger. They’re not just renting a room from you, they’ve built a routine around that home, and a cold notice breaks the trust you’ve spent years earning.

Before I draft any increase notice, I pull comparable listings within a 1 kilometer radius of the property. If similar units are renting for 10 percent more than what my tenant currently pays, I have solid ground to stand on. If the gap is only 2 or 3 percent, I usually hold off another renewal cycle rather than risk a good tenant over a marginal gain. On one of my properties near a train station, rents had climbed from 62,000 to 71,000 yen over three years for comparable rooms, so an increase to 66,000 yen still left my tenant with a clear discount and a clear reason to stay.
I also factor in my own costs. Property tax and fire insurance on my buildings have risen roughly 4 to 6 percent over the past two years, and a new water heater or repainting job easily runs 250,000 yen. When I explain the increase, I’m not inventing a number, I’m closing a gap that’s been quietly growing.
How I Frame the Conversation
I never lead with a letter. I lead with a conversation, ideally in person or by phone, at least 60 days before the lease renewal date. That gap matters. It gives the tenant time to process the news, ask questions, and plan their budget instead of feeling cornered. My approach usually follows this order:
- Open with appreciation: thank them specifically for paying on time and taking care of the unit.
- State the market fact plainly, with one or two comparable listings as reference points.
- Name the new figure and the effective date, giving at least 60 days lead time.
- Offer one small concession, such as a new air conditioner filter service or a fixed rent for 24 months instead of 12.
- Invite questions before ending the call, rather than treating the notice as final.
This structure takes maybe 10 minutes, but it turns a unilateral notice into a discussion where the tenant still feels like a partner, not a target.
Softening the Blow: Timing and Trade-Offs

Timing changes how an increase lands. I avoid raising rent right after a tenant has had a hard year, such as a job change or a hospital stay I happen to know about through casual conversation. I also avoid stacking a rent increase with any other disruption, like scheduled renovation work in the building. When I do need to combine a repair project with a rent increase, I offset it: on one property, I paid for new LED lighting throughout the common hallway, about 45,000 yen out of pocket, in the same month I raised rent by 5,000 yen. The tenant saw a tangible improvement instead of just a bigger bill.
A smaller, more frequent increase also lands better than a large one after years of no change. Raising rent by 3 to 5 percent every 2 years feels routine. Raising it by 15 percent after 5 years of silence feels like a shock, even if the total dollar gap is similar. I now build modest reviews into every renewal instead of letting rent sit frozen and then jumping all at once.
What I Say When a Tenant Pushes Back
Pushback usually sounds like this: the tenant says the increase is too much, or asks why now. I don’t get defensive. I restate the market numbers calmly and ask what would make the new rent workable for them. Sometimes that means phasing the increase over two renewal periods instead of one lump jump. On a unit where I originally proposed a 6,000 yen increase, we settled on 3,000 yen immediately and another 3,000 yen at the following renewal 12 months later. The tenant stayed, and I still reached my target rent within a year.
If a tenant simply cannot afford the new rate and has otherwise been excellent, I sometimes hold the line for one more term rather than force a move. Keeping a tenant who pays reliably and treats the unit well is worth more over 3 or 4 years than squeezing out every last yen of market rent immediately.
That’s the approach I use across all 9 of my properties: lead with respect, back the number with real market data, give people time to adjust, and leave the door open for a middle ground.
