City Gas or Propane? Understanding Your Apartment's Gas in Japan
Updated: 2026-09-12
Quick answer
Hi, I'm Miya, and I love walking newcomers through the little details of Japanese life. When you rent an apartment here, your kitchen and bath run on one of two kinds of gas: piped city gas (toshi gas) or bottled propane (LP gas). Neither one is better across the board, they just work a little differently, and it is genuinely useful to know which one your place uses.
In this guide I'll explain what each type is, why it's smart to check before you sign a lease, how the open-valve safety visit works when someone comes to turn your gas on, and who to contact to start or stop service. I'll keep it even-handed and point you to each provider and official guidance for the specifics.
City gas and propane, and how they differ
City gas, or toshi gas, is delivered to your home through underground pipes, much like your water supply. You never see a tank, the gas simply arrives at the meter and flows to your stove and water heater. It's very common in dense city areas where the pipe network already reaches most buildings.
Propane, or LP gas, comes in cylinders that are physically delivered and connected outside your building, then swapped out when they run low. You'll often find it in smaller buildings, older homes, or areas the city-gas pipes don't reach. The two types can behave a little differently at the burner and are supplied by different kinds of companies, so knowing which one you have helps you set everything up smoothly.
Why the gas type is worth checking before you rent
The gas type is usually fixed for the building, so it's not something you choose after moving in, it's something you'll want to know about while you're still deciding. It affects which company you'll contact for service and how you go about turning things on, so it's a fair question to raise with the real estate agent or landlord during your apartment search.
Ask early and there are no surprises later. When you view a place, it's perfectly normal to ask whether it's city gas or propane, and who the current gas company is. Having that written down makes your move-in day much easier, and any gas appliances you bring or buy should match the type your home uses, so it's worth confirming.
How the open-valve safety visit works
In Japan, gas isn't simply switched on from a distance. A technician from the gas company visits your home to open the main valve, check the connection, and confirm everything is working safely. You'll need to be present for this appointment, so it's one of the first things to book once you know your move-in date.
The visit itself is usually quick. The technician confirms your appliances, opens the valve, and checks for a safe setup before handing things over to you. Because you have to be home, it's a good idea to reserve a slot well ahead of your move so the timing lines up with getting your keys.
Who to contact and rough steps to start or stop service
To start service, you contact the gas company that serves your building, which you can confirm from the landlord, the real estate agent, or paperwork left in the apartment. You give them your address, your move-in date, and your contact details, then book the open-valve safety visit for a day you can be home.
Stopping service works much the same way when you move out: you contact the same company, tell them your final date, and arrange for the meter to be read or the valve to be closed. Each provider has its own forms and phone or app process, so check the specifics with your gas company and follow the official guidance they give you.
A few practical tips
Keep the gas company's name and your contract or customer number somewhere handy, together with your electricity and water details, so everything for the home is in one place. It makes future questions, moves, and appointments much simpler to handle.
Give yourself a little lead time. Booking the safety visit a week or two before you move means you're less likely to spend your first evening without hot water, and it gives you room to ask the provider anything you're unsure about while there's still time to sort it out.
Getting connected makes it all easier
Here's the thread that ties this together: gas sign-up and the safety-visit booking are almost always arranged by phone or app, and they need a contact number the company can reach you on. That means an active Japanese line with data is quietly part of getting your gas turned on, right alongside your keys and your address.
With Rakuten Mobile you can apply online with just your residence card, and eSIM-capable phones can be running the same day. Check current terms on the official page before you apply. With a working line in hand, booking that valve appointment and confirming your details becomes just one more easy step in settling in.
