How to Set Up Electricity, Gas, and Water in Japan
How to Set Up Electricity, Gas, and Water in Japan
Last updated: 2026-09-12
Once you know your address and expected key date, ask your housing contact who controls each utility. Confirm the electricity arrangement, gas type and provider, and water authority or building bill. Use the responsible provider's current start route, check its timing, book any gas-opening visit first, and save each confirmation.
Your lease, a building-wide contract, an LP-gas installation, or bundled housing may control the setup. Do not infer the provider from the neighborhood; follow written instructions for breakers, valves, meters, and appliances.
This is general moving and consumer information, not electrical, gas, plumbing, safety, housing, legal, or financial advice. Property terms and current provider instructions control. Official sources were checked on September 12, 2026.
First Confirm Who Is Responsible
| Housing situation | Ask first | Get this in writing | Do not do yet |
|---|---|---|---|
| Private rental with separate accounts | Agent, landlord, or manager | Services you open; electricity setup; gas type/provider; water authority | Do not assume a familiar company is assigned |
| Building-managed service | Landlord or manager | What is included or re-billed, contract holder, support, and move-out process | Do not open a duplicate account |
| Employer or school housing | Housing or program contact | Tasks handled for you, tasks left to you, and provider instructions | Do not assume all three are covered |
| Share house, dormitory, or furnished/monthly home | Housing operator | Bundled services, separate charges or limits, and support contact | Do not assume utilities are included |
| Missing or conflicting instructions | Manager, then named provider | One responsible party and provider for each service | Do not open a new account or share bill details until resolved |
If you have not yet confirmed the lease, included equipment, and key handover, return to the apartment rental guide. This guide starts when you have a specific home and expected access date.
Three Services at a Glance
| Service | Confirm | Start correctly | Save and route support |
|---|---|---|---|
| Electricity | Contract holder, retailer, and service area | Use a move-in request, not a supplier switch; follow breaker instructions | Retailer for bills; local network operator for outages or hazards |
| Gas | Type, provider, compatible appliances, access, and attendee | Book the authorized opening; do not connect or test equipment | Provider for bills; actual local emergency channel for danger |
| Water | Local authority or building billing | Submit the correct start notice even if water flows | Authority for bills; authority or manager for leaks |
Find the Provider for the Exact Address
- Check the housing terms, move-in pack, unit notices, and any named building provider.
- Ask the landlord, manager, or housing operator to confirm electricity, gas type/provider, water billing, hot water, and cooking equipment.
- Use the municipality's official site to identify the water authority. A building may bill water itself.
- If the electricity contract will be in your name, check that a retailer serves the address and appears on the current government registered-retailer list. Retail choice exists, but the Agency for Natural Resources and Energy notes that a whole-building contract can limit it.
- Verify the provider's domain or contact details before entering identity or payment information. A search ad, referral, unsolicited call, or door-to-door visitor does not prove assignment to the home.
Plan Backward From Key Day
There is no Japan-wide application deadline or activation promise.
| When | Action |
|---|---|
| Address and key date are stable | Confirm responsibility and the exact provider for all three services |
| Immediately after confirmation | Check each provider's current lead time and available channel; prioritize the gas-opening appointment |
| Before key day | Submit the correct start or address-transfer request and obtain written confirmations |
| On the service date | Provide only the access or attendance requested and follow the provider's instructions |
| After activation | Verify the contract name, address, plan, start date, payment path, and support details |
| Well before moving out | Check the separate stop or transfer process, access rule, final bill, and any contract-specific charge |
Tokyo Gas currently recommends about one week and requires a customer or representative at its gas-opening visit. TEPCO publishes different timing and attendance details. These are provider examples, not national rules; recheck the relevant page.
Continue with the first-month checklist for address registration, insurance, pension, My Number, mail, and the rest of the resident sequence.
Prepare the Application Information
Every row means confirm with the provider; this is not a universal document list.
| Confirm with the provider | What to prepare or ask |
|---|---|
| Service address | Accepted format, building, unit, and requested move-in notice details |
| Names and contact | Consistently spelled contract-holder/applicant names, email, and reachable phone number |
| Dates and access | Key date, start date, entry instructions, and attendee or representative if required |
| Property setup | Electricity arrangement, gas type/appliances, hot-water system, and water authority |
| Identifiers | Customer, meter, contract, or supply-point number only if requested |
| Existing account | Old-address account, stop date, and new address if moving within Japan |
| Payment | Accepted methods, how to pay the first bill, and any fees |
| Proof of request | Confirmation or reference number and the official channel used |
Do not assume a residence card, hanko, Japanese phone, bank account, card, or deposit is always required. Check the exact application and ask the provider what to do if your preferred option is unavailable.
Electricity: Start the Right Kind of Contract
- Confirm that you, rather than the building, should hold the retail contract.
- Use the retailer's move-in/start form. A supplier-switching form is for changing retailer at the same supplied address; the government's switching guide asks for existing-account identifiers that a first-time start may not have.
- If you can choose a plan, compare service area, term, charges, market-linked or bundled elements, cancellation, payment, support, and first-bill delivery. This guide does not rank retailers or predict bills.
- Follow the provider or housing instructions for the distribution board; a visit may be needed.
- Contact the retailer about the contract or bill and the local network operator for an area outage or network hazard. For a shock, sparks, burning smell, or damaged equipment, stop using or touching it and follow the property's or provider's emergency instructions.
Check an imported appliance's rating against the address's voltage, frequency, and provider instructions. As a regional example, TEPCO's English FAQ specifies 100V/50Hz in TEPCO Power Grid's transmission and distribution area—not all Japan. A matching plug or adapter does not prove compatibility.
Gas: Confirm the Type and Book the Opening
Establish whether the home uses city gas, LP gas, another system, or no gas. Confirm the provider and specification before buying or using an appliance. City-gas and LP-gas equipment is not interchangeable; the Immigration Services Agency's Guidebook on Living and Working says equipment must match the gas type.
Use the provider's start procedure. Ask:
- whether the contract holder or an authorized adult representative must attend;
- what access and installed or furnished appliances the technician needs;
- what the technician will inspect and start; and
- which number is the local emergency contact for this address.
Tokyo Gas, for example, requires a customer or representative at opening while its technician tests ignition and explains safety. Rules differ. Do not open a valve, connect or convert an appliance, test for a leak, or repair gas equipment.
Gas may power hot water, cooking, both, or neither. Confirm the installed systems.
If you smell gas: Do not use a flame or operate electrical switches. Move away and follow the actual local gas network or provider's emergency instructions. The Tokyo Gas Network warning supports these precautions in its area, but its phone number is not a national gas number. Do not investigate the source yourself.
Water: Use the Local or Building Process
Identify the municipal water bureau, local water-supply business, or building-side billing arrangement for the exact address. Complete its current start procedure even if water already flows. Confirm whether sewerage appears on the same bill, how meters are read, which payment methods are accepted, and who handles a leak inside the unit versus a building-side or public-system problem.
Local pages show why the address matters. The Tokyo Waterworks application covers the 23 wards and specified Tama municipalities, not every Tokyo address or all Japan. Osaka City uses its own start, payment, stop, and leak routes. Find the authority for your home.
Follow property or water-authority directions for shutoff valves and leaks; do not guess who owns a pipe or meter.
After Activation: Save a Private Account Record
Keep this record securely, fill it only from confirmed details, and never send completed identity, account, meter, or payment records to Omnishoku.
| Record | Electricity | Gas | Water |
|---|---|---|---|
| Responsible party / provider | |||
| Contract-holder name | |||
| Customer or account number | |||
| Supply-point or meter ID, if applicable | |||
| Start date / plan | |||
| Payment / billing cadence / first expected bill | |||
| Login / official support channel | |||
| Local emergency or outage contact | |||
| Stop or transfer method / notice instruction |
Check the first bill's name, address, plan, usage period, charges, payment method, and due date. Fixed and usage-based components and payment routes vary. Do not assume monthly billing, overseas-card acceptance, or convenience-store payment.
Add deposits, first bills, and recurring utility categories to your moving budget. If account access depends on mobile data, calls, or SMS, handle that separately with the Japan phone and SIM setup guide.
Avoid an Unwanted Switch or Sales Contract
Before agreeing to electricity or gas service:
- identify the contracting company and verify its official site or registered details;
- read the plan, all charges, contract term, cancellation conditions, and written disclosures;
- keep the contract document and every confirmation; and
- do not show a bill or share a customer or supply-point number with an unverified salesperson.
The National Consumer Affairs Center's English warning describes door-to-door approaches that claim to represent the whole building and seek information from a meter-reading slip. Confirm any such claim with the landlord or manager. For an unresolved electricity or gas sales or contract concern, first contact the contracting company. The Electricity and Gas Market Surveillance Commission's consumer Q&A provides information and a consultation route, but the commission says it does not mediate or arbitrate individual disputes.
Moving Out or Moving Within Japan
New-address service does not necessarily close an old account. For each utility:
- Use the correct stop, transfer, or new-address procedure—not a same-address switch.
- Give addresses and dates only through the official channel.
- Confirm any old-home gas or meter access.
- Save the stop confirmation and final meter or bill record.
- Keep payment and contact routes active through the final bill.
- Check for contract-specific cancellation charges.
Returning keys, filing a municipal moving notice, or signing with a provider at the new home does not by itself prove that the old accounts are closed.
Who to Contact When Something Is Wrong
| Problem | First route |
|---|---|
| Included service, building access, installed equipment, or property-side fault | Landlord, housing operator, or management company |
| Application, plan, bill, payment, name, or account change | Contracted retailer, gas provider, or water authority |
| Area outage, gas smell, exposed wire, or infrastructure hazard | Actual local network operator or provider emergency channel saved for the address |
| Unknown water authority or local language-access route | Municipality or foreign-resident desk |
| Unresolved electricity or gas sales or contract concern | Contracting company, then the appropriate commission or consumer-affairs channel after checking its scope and language access |
Do not use an ordinary billing contact as an emergency line, and do not use a Tokyo or Osaka number for a home outside that operator's stated area.
Final Move-In Check
- Responsibility for electricity, gas, and water is confirmed separately.
- The exact service area, gas type, and water authority or building bill are known.
- Start requests and any gas appointment are confirmed.
- Attendance, access, appliance, and payment instructions are understood.
- Contract, customer, support, outage, emergency, and move-out details are saved privately.
FAQ
Are electricity, gas, and water included in Japanese rent?
Sometimes, but housing type does not decide the answer. Check the signed terms and ask who holds and bills each contract. Managed housing may bundle one service and leave another to the resident.
How early should I arrange utilities?
As soon as the address and key date are stable, check each provider's current lead time. Check gas first because opening may require an appointment; there is no national deadline or guaranteed activation time.
Can I choose my electricity or gas company?
Possibly. Choice depends on service area, whose name holds the contract, property terms, a whole-building arrangement, and the gas system. Confirm those facts before comparing plans.
Do I need a Japanese bank account or credit card?
Not as a universal rule. Payment methods and first-bill fallbacks differ by provider and contract. Check the exact application before opening a bank account or card solely for utilities.
Do I need to be home when the gas is opened?
Many provider-led gas openings require the customer or an authorized representative because a technician needs access for safety work. Confirm who may attend and what access is required with your actual provider.
Why is the water running if I have not registered yet?
Water flowing does not prove that the account or billing arrangement is complete. Identify the local authority or building process and submit the required start notice.
Is hot water controlled by the gas account?
It may be, but some homes use electric or other water heating. Ask what equipment is installed and which service powers it before move-in.
What must I do with utilities when I move out?
Check and complete each provider's stop or transfer process, arrange any required access, keep confirmations, and leave a payment route open for the final bill. A key return or municipal moving notice is not a utility cancellation.
