Moving into a new apartment in Japan is exciting — but before you can cook a meal or take a hot shower, you need to set up your utilities. If you're wondering how to set up utilities in Japan as a foreigner, you're not alone. The process can feel confusing, especially with the language barrier. The good news: it's very manageable once you know the steps. This guide walks you through electricity, gas, and water clearly and simply.
What to Expect Before You Start
In Japan, utilities are generally set up separately for each service. In most cases, water is already running when you move in, electricity can be activated quickly online or by phone, and gas requires an in-person inspection before it can be turned on. Timelines and procedures vary slightly depending on your city and provider, so treat this as a practical guide and confirm the latest details with your specific provider.
You will typically need the following documents or information ready:
- Your name (as it appears on your residence card)
- Your new address in Japan
- Your move-in date
- Your phone number (a Japanese number is strongly recommended)
- Your bank account details or a credit card for billing (some providers also accept convenience store payment)
- Your residence card (you may be asked to confirm your address registration)
Setting Up Electricity
Who provides electricity?
Japan's electricity market was deregulated, so there are now multiple providers. However, the major regional companies — such as TEPCO in Tokyo, Kansai Electric in Osaka, and Chubu Electric in Nagoya — are the most common starting point. Check which company serves your area.
How to apply
Most major electricity providers now offer an English-language online application form or an English phone option. The process is usually straightforward:
- Go to your regional provider's official website and look for a "Start Service" or "Move-in" section.
- Enter your address, move-in date, and contact details.
- Choose a billing method (bank transfer is most common; you'll need your bank account number and branch code).
- Submit your application — usually at least a few days before your move-in date.
In many cases, you do not need to be home for electricity to be activated. The breaker box in your apartment is simply switched on remotely or by the building. Confirm this with your provider when you apply.
Estimated costs
Electricity bills vary depending on usage, season, and plan. As a general guide, a single person in a small apartment might pay roughly ¥3,000–¥8,000 per month, but costs can be higher in winter or summer due to heating and air conditioning. Always check the latest rate information on your provider's official site.
Setting Up Gas
Important: you must be home for the gas inspection
Unlike electricity, gas cannot simply be switched on remotely. A technician from the gas company must visit your apartment to inspect the equipment and turn on the supply. This is a safety requirement — do not try to use gas appliances before this visit.
How to apply
- Find out which gas company covers your area. Your landlord or real estate agent can tell you this. Common providers include Tokyo Gas, Osaka Gas, and Toho Gas.
- Contact them by phone or through their website to book a visit. Some providers have English support lines — check the official website for availability.
- Choose a date and time slot when you will definitely be home.
- The technician will arrive, check all gas appliances (stove, water heater, etc.), and turn on the supply. The visit usually takes 15–30 minutes.
- Register your billing method after the visit, either online or by returning the payment form sent to your address.
Try to book your gas inspection for your first or second day in the apartment so you are not without hot water for too long.
Estimated costs
Gas bills for a single person typically range from around ¥2,000–¥5,000 per month as a rough guide, and more in winter. Confirm the latest tariffs on your provider's official site.
Setting Up Water
In most Japanese apartments, the water supply is already connected and ready to use when you move in. However, you are responsible for registering as the account holder so that bills come in your name.
How to register
- Contact your local municipal waterworks office (水道局, suidō-kyoku). This is run by your city or ward government, not a private company.
- You can usually register online, by phone, or in person. Some municipalities have English support; others may require a Japanese speaker to help.
- Provide your name, new address, and move-in date.
- Set up a payment method — bank transfer is standard.
If your landlord or real estate agent manages the water billing on your behalf (this happens in some buildings), ask them to confirm the arrangement before you contact the waterworks office yourself.
Estimated costs
Water bills in Japan are typically billed every two months. As a rough guide, a single person might pay around ¥2,000–¥4,000 per two-month period, though this varies by municipality and usage. Check with your local office for current rates.
Useful Tips for Foreign Residents
- Get a Japanese phone number first. Most utility applications require one. A SIM card from a provider like GTN Mobile or IIJmio can be set up relatively quickly even as a new resident.
- Open a Japanese bank account early. Bank transfer (口座振替, kōza furikae) is the most common and convenient payment method for all utilities. If you haven't opened an account yet, some providers temporarily accept convenience store payment slips while you get set up.
- Ask your real estate agent for help. They often know the local providers and can assist with the first contact, especially for gas bookings.
- Keep your move-in date in mind. Try to apply for electricity and book your gas inspection before or on the day you move in, so you have everything running from the start.
- Translation apps help. If you receive a form or letter in Japanese, apps like Google Translate's camera function can help you understand the key fields quickly.

Setting up utilities in Japan as a foreigner takes a little preparation, but it is absolutely doable — even with limited Japanese.
