Three years ago I opened a denki (electricity) bill for 47,000 yen and nearly choked u2014 a tenant had moved out two months earlier, but the account was still sitting in my name from when I’d set it up during the vacancy. Nobody had switched it over, and the new tenant had been running the air conditioner all summer on my dime. That single mistake is why I now check utility registration on every single one of my 9 units, every time someone moves in or out.
If you self-manage even a couple of properties, this is one of those quiet problems that doesn’t announce itself. It just shows up three months later as a bill you weren’t expecting.

Why Utilities End Up in the Landlord’s Name

Build the knowledge base that separates professional landlords from amateur ones.
It usually starts innocently. When a unit sits empty, I keep the electricity and water accounts active under my own name so I can run lights and a dehumidifier during showings u2014 mold control alone justifies the 800 to 1,500 yen a month it costs me. Then a tenant signs a lease, moves in, and simply starts using what’s already connected instead of opening their own account. In my experience, roughly 1 in 5 new tenants never bothers to make the switch unless someone tells them to, because in Japan utility transfers aren’t always bundled into the move-in paperwork the way rent and key money are.

Landlord-Tenant Law Guides
Know exactly what you can and cannot do u2014 essential reading before any dispute.
This isn’t just an annoyance u2014 it’s a direct hit to your cash flow and your liability. Here’s what I’ve actually dealt with across my properties over 15 years of doing this myself:
- Unpaid usage bills landing in my mailbox weeks or months late, sometimes over 40,000 yen for a single billing cycle
- Reconnection fees of around 1,200 to 3,000 yen when a tenant lets an account lapse and the utility company shuts it off, then bills the account holder u2014 me u2014 for restoring it
- Disputes at move-out where a tenant claims usage wasn’t theirs, because the account never had their name on it to prove otherwise
- Insurance and liability gaps, since some renters insurance policies want the utility account to match the resident’s name for certain claims
On one property I manage near a train line, I let this slide for four months with a new tenant before I noticed the water bill hadn’t changed hands. By the time I caught it, I was out about 22,000 yen I never fully recovered, because by then the tenant had already moved again.
My Step-by-Step Process for Transferring Utilities
These days I treat the utility transfer as a hard requirement of move-in, not a suggestion. Here’s exactly what I do now for every new lease:
Setting the Deadline Before Keys Change Hands

Property Inspection Forms & Checklists
Document everything. A signed checklist at move-in prevents every deposit dispute.
I tell every incoming tenant, in writing, that electricity, gas, and water accounts must be transferred to their name within 3 days of the move-in date. I include the utility company phone numbers and account numbers directly in the move-in packet so there’s no excuse about not knowing who to call. For gas specifically, most providers in Japan require an in-person appointment to turn the pilot light back on, so I tell tenants to book that appointment before moving day, not after u2014 otherwise they can go a week without hot water.
Verifying the Switch Actually Happened
I don’t just take their word for it. Around day 5, I call or check the utility company’s online portal to confirm the account has moved off my name. This takes maybe 10 minutes per unit, and it has saved me from at least six situations where a tenant said they’d handled it but hadn’t. If the transfer hasn’t happened, I follow up immediately rather than waiting for the next bill to surface the problem.
What to Do When a Tenant Refuses to Switch
Occasionally you’ll get a tenant who just won’t do it u2014 maybe they don’t have a bank account set up yet, or they’re waiting on a residence card. When that happens, I don’t let the account sit indefinitely in my name with no protection. Instead, I add a clause to the lease (or a signed addendum for existing tenants) stating that any utility usage charges billed to the landlord’s account will be re-invoiced to the tenant with a 10% administrative surcharge, due within 14 days. That surcharge alone has motivated more than one slow-moving tenant to finally make the call. In the rare case where a tenant simply won’t cooperate after two written notices, I’ve had to make the switch on their behalf using a limited power of attorney form some utility companies accept u2014 though that’s a last resort, maybe twice in 15 years.
Building a Safeguard Into Every Future Move-In
The real fix isn’t chasing down problems after they happen u2014 it’s designing your move-in process so the gap never opens in the first place. I now keep a simple checklist taped inside my property management binder for every unit, and I don’t hand over keys until every box is checked off. It’s a small habit, maybe 15 extra minutes of paperwork per tenant, but it has eliminated a recurring cost that used to blindside me two or three times a year.
That’s the approach I use across all 9 of my properties now u2014 treat the utility transfer as part of the lease signing, not an afterthought, and you’ll never open another surprise bill for someone else’s electricity.
