Kanazawa City Failed to Collect Sewage Fees for 31 Years — Backlash as 20 Households Get Hit with Lump-Sum Bill for 5 Years

The story

It has come to light that Kanazawa City’s Public Enterprise Bureau failed to collect sewage fees for 31 years from some residents and shops in a building within the city. The affected parties number 20 out of 28 households, and the city plans to bill them in a lump sum for the past 5 years — the maximum period covered under the statute of limitations set by the revised Civil Code. The sudden lump-sum billing has reportedly sparked backlash from the affected households. On 5ch, opinions clashed: some said “of course they should pay what they always owed,” others sympathized that “a lump sum is too harsh, it should be split into installments,” and still others were skeptical, arguing “there’s no way you wouldn’t notice 5 years of missing bills” — with views divided over whether the residents themselves were also at fault.

Just bill them gradually, no big deal.
3AnonymousSep 15, 2026 23:18
A lump sum all at once is a bit much… Maybe letting anyone who wants it split it over 2 years would be a fair compromise.

Re: #3
Only having to pay 5 years out of 31 is actually a huge win for them.
151AnonymousSep 16, 2026 05:57
Re: #3
The bill itself is issued as a lump sum, but you can pay it off in installments, you know.
5AnonymousSep 15, 2026 23:18
Re: #1
They probably knew they weren't paying and just kept quiet about it.
Collect a penalty on top of it too.

Re: #5
Most people don't really scrutinize their water bill statement.
You wouldn't notice whether you're being undercharged or overcharged either way.
31AnonymousSep 15, 2026 23:36
Re: #8
They knew about it — that's why other residents filed a complaint.
60AnonymousSep 16, 2026 00:13
Re: #8
It's not that they were undercharged, they weren't charged at all.
There's no way they didn't notice that.
6AnonymousSep 15, 2026 23:19
Wasn't the statute of limitations on a missed bill only about 2 years?
45AnonymousSep 15, 2026 23:54
Re: #6
That's right for civil claims.
58AnonymousSep 16, 2026 00:09
Re: #6
There was a major Civil Code revision in 2020.
Before that, there were shorter limitation periods for things like dining and lodging, starting from as little as 1 year,
but now it's whichever comes first: 5 years from when you become aware you can make the claim, or 10 years even if you never knew.

> Following complaints of "this is unfair" from residents who had been paying the fee

It's a mystery how they even found out, but that's a pretty small-minded complaint to make.
13AnonymousSep 15, 2026 23:22
Re: #9
Did they figure that crying "unfair" might get their own fees waived too?
124AnonymousSep 16, 2026 03:25
Re: #9
They said 20 out of 28 households in this building weren't billed, so maybe residents compared notes with each other and realized some households weren't being charged at all.
14AnonymousSep 15, 2026 23:25
They never paid a cent until now, and they're mad about being billed for just 5 years? Are they stupid? (lol)
19AnonymousSep 15, 2026 23:28
Re: #14
Well, a lump sum is bound to cause backlash.
It is the city's own screwup, after all.
17AnonymousSep 15, 2026 23:27
Wasn't it only a 1-year statute of limitations if they never billed at all?
130AnonymousSep 16, 2026 03:47
Re: #17
Yeah, I kind of feel that way too…
42AnonymousSep 15, 2026 23:51
Paying 100,000 yen (about $650) all at once? No way.
43AnonymousSep 15, 2026 23:52
I once got a refund for an overpayment, but
apparently anything older than 5 years is past the statute of limitations.
51AnonymousSep 15, 2026 23:58
Re: #43
That's exactly why it's 5 years this time too.
46AnonymousSep 15, 2026 23:55
Sounds like the limitation period is 5 years.
Hitting them with it all at once still seems harsh though.
64AnonymousSep 16, 2026 00:15
Re: #60
Sewage fees are bundled into the tap water bill — the whole system calculates it based on how much tap water you use.
They were paying for their water usage, so they probably just assumed that was normal.
160AnonymousSep 16, 2026 06:12
Re: #64
Since it's usually folded into the water bill, maybe they just weren't using tap water?
Even if you're on spring water, you still owe sewage fees, right?
65AnonymousSep 16, 2026 00:16
They probably just thought "lucky, no bill came," but
that in itself seems pretty reckless.
67AnonymousSep 16, 2026 00:29
Re: #65
Even so, the responsibility lies with the city.
92AnonymousSep 16, 2026 01:13
Before chasing down the unpaid bill, shouldn't they just shut off the water main first?
137AnonymousSep 16, 2026 04:32
Re: #92
I wonder what happens if you pay your tap water bill properly but fall behind on sewage fees…
Do they just shut the sewage line and it all backs up out of the drain?
93AnonymousSep 16, 2026 01:13
I never even knew sewage fees were billed separately.
Never once thought about it.
97AnonymousSep 16, 2026 01:19
Re: #93
For a household in Kanazawa using both water and sewage service, not knowing that is pretty strange.

The reason is that the bimonthly bill lists the tap water charge, the sewage charge, and the combined total.

If you actually look at the bill, the breakdown is right there.
104AnonymousSep 16, 2026 01:47
Anyone would notice paying 0 yen in water fees for 5 years straight.
These people knew and kept quiet — and there were 20 households doing it.
They must have known this day would come eventually, so just pay up already.
Don't be so entitled.
108AnonymousSep 16, 2026 02:05
Re: #104
I can't say for certain, but…

In Kanazawa, sewage usage requires registering with the city.
Without that registration, you only get billed for tap water.

So it's probably the case that they were only ever billed for tap water.
Can't say for sure though.
109AnonymousSep 16, 2026 02:07
Re: #104
They'd still be getting billed for tap water.
Your "water bill" is the tap water charge plus roughly another 10% on top for sewage —
that's just common knowledge.
110AnonymousSep 16, 2026 02:08
Re: #104
Do you think the tap water was 0 yen too?
It's only the sewage portion that went uncharged.

Background and Key Points of This Story

In many municipalities, sewage fees are folded into the combined water bill, so plenty of users never pay attention to the breakdown. This case stems from a 31-year-long administrative failure on the part of Kanazawa City’s Public Enterprise Bureau — likely a flaw in its billing system or in how registrations were processed — a management lapse on the government’s side, which is a different matter from any failure by residents to self-report. The focal point is the 2020 revision of the Civil Code, which unified the statute of limitations for debt claims at “5 years from when the creditor becomes aware of the claim”; the city is now billing retroactively for the full 5-year maximum this allows. In the thread, the detail that “payment can be made in installments” eased some of the backlash over the lump-sum bill, while skepticism that “it’s unnatural not to notice 5 straight years without a single bill” ran alongside a defense that “staying quiet even after noticing doesn’t necessarily make you at fault” — leaving opinions split over whether residents bore any responsibility. Though not stated in the article itself, there’s a notable skew in that only 20 of the 28 households in the same building were affected, and the original report never clarifies why only some households were missed.
