Mortgage Variable Rates: Two Major Banks Hike Rates Starting September, Reflecting BOJ Rate Increase

From our other sites

The story

On the 31st, Mitsubishi UFJ Bank and Sumitomo Mitsui Banking Corporation announced the mortgage rates that will apply in September, raising the best variable rate — the option most borrowers choose — from the previous month. This reflects the Bank of Japan’s policy rate hike decided in June, and all five major banks have raised their best 10-year fixed rate. On 5ch, threads featured complaints about rising repayment burdens, reports on how people’s own rates had actually changed, and questions about the rate gap with the Flat 35 fixed-rate loan. Opinions were split over whether variable or fixed rates are the better deal, with many also worried about the impact on the generation about to buy homes.

Re: #1
They're raising it by double digits (basis points)? The BOJ's merciless.

Re: #8
It's not like the BOJ sets that rate directly, though.

I'm on Flat 35 fixed, so nankurunaisa for me… (Okinawan phrase for 'it'll all work out')

Re: #9
I hear about Flat 35 a lot, but is the fixed rate actually 3.5%? Isn't variable still way cheaper?

Re: #46
In my case I started 9 years ago, so…

Re: #46
No no, the "35" in Flat 35 refers to the 35-year fixed term, not the rate. The applicable rate changes monthly and varies quite a bit depending on the loan conditions. I posted the base rate in Re: #32.

I want to ask someone who actually knows this stuff — does raising rates mean less work for small regional sash (window frame) makers? Could they go under?
15AnonymousAug 31, 2026 22:25
Re: #11
No effect if the interest rate on the company's own borrowing doesn't rise. But if people start avoiding custom-built or new homes because they hate rising mortgage rates, sash orders will drop over the long run, revenue falls, and yeah, less work.

How would you even know if a company has borrowings? By the way, apparently my company has zero debt.
42AnonymousAug 31, 2026 22:44
Re: #20
Huh, a debt-free company in this day and age. But borrowing can also be a sign of corporate strength when it comes to growth — there's a view that being able to borrow from a bank equals having credibility. You can tell if a company has debt by checking its financial statements; a corporation has to disclose them anyway.

Heard a rumor that the variable rate will hit 1.9% by year-end. Fixed will be 4%.

Re: #24
And what happens then? Jobs?
32AnonymousAug 31, 2026 22:32
Checked the Flat 35 rate — it was 2.08% this January, and it's already 3.29% by August.
33AnonymousAug 31, 2026 22:35
People buying homes right now are getting hit with a double whammy — houses themselves are already expensive due to soaring material costs and the weak yen, plus now rising interest on top of that.

Re: #33
Buying a house now is seriously rough. I built mine 15 years ago when the variable rate was 0.75%. Back then there was also the Eco Points housing subsidy worth 300,000 yen, and I think consumption tax was still 8%. The home builder even threw in a free 20-tatami-mat AC unit and a storage heater. Now curtains and bath/toilet fixtures have all gone up in price, consumption tax is 10%, rates are high, and even looking at flyers from the same builder I used, house prices are up 20%. I'm just a low-level salaryman, but I'm really glad I built my house when I did. Come to think of it, fire insurance has gone up too.

Re: #33
Exactly like the 1989 bubble. Ordinary people end up house-hunting one prefecture over — sure, houses versus condos are different — but once it burst, nearby areas in neighboring prefectures became affordable.
47AnonymousAug 31, 2026 22:46
Now that the negative spread on the mortgage tax deduction is gone, why not bring the deduction back up to 1%?

If they don't, fewer suckers will buy houses — wonder what they'll do.

According to the old-timers on 5ch, renting is unbeatable! Or so they say.

Rent going up tens of percent every two years, though.
56AnonymousAug 31, 2026 22:53
Going forward nobody's going to be able to afford a house or a condo — more and more people will just rent for life.

Tiny houses are just going to become the standard from here on.

Doesn't bother me one bit!!

Still got 40 million yen left on my loan.

As long as it doesn't go up, it's no big deal.
Grr! Nothing ever goes my way…
Not yet! It's not over yet!

Re: #61
Just pay off the remaining balance in one go.
64AnonymousAug 31, 2026 23:00
House already bought, no mortgage left. We're a power couple with two kids — husband in his late 40s, wife in her early 40s. Already have 70-80 million yen in financial assets, should hit 100 million in about 3 more years. Combined retirement payouts alone are projected at 55 million yen.

I'm basically unbeatable, right?

Doesn't it feel empty, bragging when nobody's engaging with you?

About the level of downgrading your once-a-month treat from a fancy steakhouse to a Gusto family restaurant. (Mansei is an upscale steakhouse chain; Gusto is a cheap family-restaurant chain)
88AnonymousAug 31, 2026 23:19
See? Even so, fixed is still more expensive, right? Which means anyone who takes out a fixed-rate loan is pretty dumb.
91AnonymousAug 31, 2026 23:21
Re: #88
My fixed rate is 1.25% lol
93AnonymousAug 31, 2026 23:23
Just checked and my variable rate is 1.625%. Does it vary person to person?

167AnonymousSep 1, 2026 04:41
Re: #93
Depends on the bank. Within the same bank at the same time, there's no individual variation.
174AnonymousSep 1, 2026 06:04
Re: #93
Just checked mine — it went from 1.095% to 1.295%. This month happened to be my review month.

Background and Key Points of This Topic

Variable mortgage rates aren’t tied directly to the BOJ’s policy rate itself, but rather to each bank’s own “short-term prime rate.” What’s being reflected now is the rate hike the BOJ decided in June — since banks only revise their rates a few times a year, changes to storefront rates show up with a lag of several months. It’s also a common misconception on the thread that “variable rate goes up = monthly payment increases immediately.” In fact, most banks only review the actual monthly payment amount once every 5 years, and cap any increase at 125% of the previous payment under the “five-year rule” and “125% rule” — so a rate hike doesn’t necessarily hit household budgets right away. Opinions in the thread were split on whether variable or fixed is the better deal, and there were repeated questions about Flat 35’s rate levels — but it’s easy to misunderstand that Flat 35 is the product name for a full-term fixed-rate loan handled by the Japan Housing Finance Agency, and the actual rate applied varies by which financial institution handles it and the loan conditions.
