Setting up utilities in Japan is one of the first practical tasks you will face as a new foreign resident — and it can feel overwhelming if you are not sure where to start. From figuring out which electricity company to contact to understanding gas safety checks, the process of utilities Japan setup involves several separate steps, each with its own paperwork and timeline. The good news is that it is very manageable once you know what to expect. This guide walks you through each utility clearly, so you can get your home running as quickly and smoothly as possible.
Understanding How Utilities Work in Japan
Unlike some countries where utilities are bundled or handled by your landlord, in Japan each utility — electricity, gas, and water — is typically contracted separately and in your own name. When you move into a new apartment, the previous tenant's contracts are usually already cancelled, so you need to set up new ones yourself. The good news is that many providers now offer online sign-up and some even have English support.
A few things to know before you begin:
- You will need your new address (exact apartment number included) before you can apply.
- A Japanese phone number is almost always required for registration.
- Payment is usually by bank account direct debit (口座振替) or credit card — cash payment is possible but less common.
- Some forms will be in Japanese only, so a translation app or a helpful neighbour can be useful.
Setting Up Electricity
Who provides electricity?
Japan's electricity market was deregulated, so depending on your region, you can choose from the traditional regional provider (such as TEPCO in Tokyo, Kansai Electric in Osaka, or Chubu Electric in Nagoya) or a newer alternative provider. Regional providers are the simplest starting point for newcomers.
How to apply
Most regional providers allow you to apply online or by phone. You will generally need:
- Your new address and room number
- Your move-in date
- A contact phone number
- A payment method (bank account or credit card)
- The supply point number (お客さま番号 or 供給地点特定番号) — usually found on a sticker inside the breaker box or on a card left by the previous tenant
Electricity can often be turned on remotely without anyone visiting your home, which makes it the easiest utility to set up. Apply at least two to three days before your move-in date to be safe.
Setting Up Gas
Important: an inspection visit is required
Gas is the utility that requires the most planning. Unlike electricity, a technician from the gas company must visit your home to inspect the gas appliances and safely turn on the supply. You need to be present during this visit. The inspection is free and usually takes around 30 minutes, but appointment slots can fill up quickly — especially at peak moving seasons (March and April).
How to apply
Contact the regional gas provider for your area (for example, Tokyo Gas, Osaka Gas, or Toho Gas). You can usually apply online or by phone. You will need:
- Your address and move-in date
- A preferred date and time for the inspection visit
- A contact phone number
- Payment details
Try to book your gas appointment as soon as you know your move-in date, particularly if you are moving in spring. Without gas, you will have no hot water or heating (in many apartments), so this one should be a priority.
Setting Up Water
How water supply works
Water in Japan is managed by local municipal waterworks bureaus, not private companies. In most cases, water is already running when you move in because it is connected at the building level. However, you are still responsible for registering the contract in your name and for paying the bills.
How to apply
Visit or contact your local city or ward office (市区町村) water department, or check their website. Many now offer online applications. You will typically need:
- Your new address
- Your move-in date
- A bank account for direct debit payment
In some areas, the process is handled automatically through your ward office when you register your address (住民登録). Ask your landlord or real estate agent whether you need to take any separate action.
Utility Setup at a Glance
| Utility | Who to contact | Home visit needed? | Typical lead time |
|---|---|---|---|
| Electricity | Regional provider (TEPCO, Kansai Electric, etc.) or alternative provider | Usually no | 2–3 days before move-in |
| Gas | Regional gas company (Tokyo Gas, Osaka Gas, etc.) | Yes — you must be home | Book as early as possible |
| Water | Local municipal water bureau or ward office | Usually no | Register around move-in date |
Details and timelines vary by region and provider. Always confirm the latest requirements on the official provider or municipality website.
Practical Tips for Foreign Residents
- Use a translation app. Google Translate's camera mode can read Japanese forms in real time. Many utility websites also have simple layouts that are easier to navigate once you know what each field means.
- Ask your landlord or real estate agent. They often know exactly which providers serve your building and can point you to the right contact numbers. Some landlords will even help you with the initial application.
- Set up a Japanese bank account early. Direct debit from a local bank account (such as Japan Post Bank / Yucho) is the most common and hassle-free way to pay utility bills. Having an account ready before you move in saves time.
- Keep your utility receipts and account numbers. These may be asked for when you apply for other services or when you eventually move out.
- Check if your building uses city gas or propane (LP gas). LP gas is common in smaller buildings and rural areas, and is usually supplied by a different local company. The setup process is similar, but costs can differ.
- Electricity plan comparison. Once you are settled, it may be worth comparing electricity plans online (providers like Enechange offer comparison tools in Japanese). You could save money each month, especially if you work from home. Confirm any plan details directly with the provider before switching.
What About the Language Barrier?
Many utility providers in major cities now offer at least basic English-language support, either on their websites or by phone. TEPCO, for example, has an English hotline as a guide — check the official TEPCO website for current contact details. Tokyo Gas also has multilingual support options. If you are in a smaller city or rural area, English support may be limited, and your local international residents' centre (外国人相談窓口) can often help you navigate the process in your language for free.
Summary: Getting Your Utilities Running in Japan
Sorting out utilities Japan setup is genuinely one of the more manageable parts of moving here — it just takes a little planning. To recap: apply for electricity online a few days before you move in, book your gas inspection as early as possible and make sure you are home for it, and register your water contract with your local municipality around move-in day. Having a Japanese bank account ready makes paying bills straightforward each month.
Thousands of foreign residents go through this process every year, and with the steps above, you are well prepared to do the same. Take it one utility at a time, confirm the details with each official provider, and you will have a fully functioning home before you know it. Welcome to Japan — you have got this.
