The Basic Rule: Utilities Usually Do Not Transfer Automatically
One of the easiest mistakes to make after signing a Japanese apartment contract is assuming the home will simply "turn on" when you arrive. In Japan, utilities are often not transferred automatically between tenants. Even if the apartment looks ready, you usually need to register separately with each provider or confirm whether the management company has already arranged part of the setup.
That means your move-in plan should include four separate systems:
- gas
- electricity
- water
- internet
Of these, gas is the most urgent for comfort, and internet is the slowest to arrange well.
Before You Start: Ask the Landlord or Agent These Questions
Before calling anyone, confirm these basics with your landlord, real estate agent, or building manager:
- Which providers currently serve the apartment?
- Is the apartment using city gas or LP / propane gas?
- Is water handled directly by the city, or through the building management?
- Does the building already have fiber infrastructure?
- Are there designated internet providers or contract restrictions?
- Are any utility account numbers or meter numbers already listed in the move-in documents?
Ten minutes of clarification can save you multiple wrong applications.
Gas (ガス): The Utility You Must Not Forget
Gas is usually the highest-priority utility because it often powers:
- hot water
- kitchen stove
- room heating in some homes
If gas is not activated, you may discover on your first night that you can neither shower properly nor cook.
Why Gas Is Different
Unlike electricity, gas typically requires a technician visit to turn it on safely. Someone must usually be home during the appointment.
Two Main Types of Gas
City Gas (都市ガス) — generally cheaper, and common in dense urban areas. Since Japan liberalized the gas market in 2017, some households can choose among providers or bundled plans depending on region.
LP Gas / Propane (プロパン / LPガス) — common in smaller buildings and regional areas, usually more expensive, and the provider is often effectively fixed by the building or landlord.
Major Regional Providers
In the Tokyo area, many people deal with Tokyo Gas. In Osaka, Osaka Gas is a major name. Other regions have their own dominant providers or retail sellers.
You do not need to memorize every regional company in advance. What matters is knowing which one serves your address.
How to Set Up Gas
Typical steps:
- confirm the provider and meter details
- contact the provider by phone or online
- give your address and move-in date
- schedule the opening appointment — usually a two-hour window
- stay home for the visit and show ID if requested
The visit itself takes around 15 minutes: the technician opens the meter, checks the appliances, and shows you how to turn the gas off in an earthquake. Book it for your move-in day if you can, and have someone there from the start of the window.
Typical Gas Bill
For a single person in a city-gas area, expect roughly ¥3,000–¥6,000 a month — more in winter if you use gas for heating, less in summer. The standing charge is a decent slice of that, so the bill does not fall to zero in a month when you barely cook.
Information You Will Usually Need
- full address
- move-in date
- preferred activation date and time
- your name exactly as used on the contract
- phone number
- meter number if available
Practical Risk to Avoid
If your apartment uses gas for hot water and you forget setup, you may move into a functioning apartment with no hot shower. For that reason, book gas before move-in day whenever possible.
Electricity (電気): Usually the Easiest Utility
Electricity setup is typically much easier than gas. In many cases, no visit is required and you can complete the process online or by phone.
Provider Choice Since Liberalization
Japan liberalized the electricity market in 2016, which means many residents can choose among providers, plans, and bundles.
Major Regional Names
Common regional players include:
- TEPCO in the Kanto area
- Kansai Electric in the Kansai area
- Chubu Electric in central Japan
There are also many retail resellers that bundle electricity with gas, internet, or point programs.
How to Set Up Electricity
Typical steps:
- identify the current or available provider
- apply online or by phone
- provide your address and move-in date
- provide the meter number (メーター番号) if requested
- receive confirmation of the start date
When Will You Get the First Bill?
Usually the first bill arrives 1 to 2 months after setup, depending on the billing cycle. That sometimes surprises new residents because electricity appears to start instantly, but the payment paperwork trails behind.
Should You Compare Plans?
If you are staying long term, yes. If you just arrived and are overwhelmed, pick a straightforward plan first and optimize later. In the first week after moving, reliability matters more than shaving off a tiny monthly amount.
Subsidies and Rate Support
Households with a standard regulated tariff have had electricity and gas bills supported by government subsidies in recent years. The fiscal 2026 round ran from July to September: ¥3.5, ¥4.5 and ¥3.5 per kWh for electricity in July, August and September, and ¥14, ¥18 and ¥14 per cubic meter for city gas over the same three months. You do not apply for it — the retailer deducts it from the bill automatically. For a typical household it came to around ¥5,000 in total. Subsidy rounds are announced season by season, so check your retailer's notice before assuming it has ended.
Typical Electricity Bill
A single person in a small apartment usually pays ¥5,000–¥8,000 a month for electricity, with July–September and January–February noticeably higher if you run the air conditioner or a heater. All-in electricity, gas and water for one person generally lands between ¥12,000 and ¥18,000.
Water (水道): Usually Simple, Sometimes Already Handled
Water in Japan is generally managed by municipal governments rather than private national utility brands. That means the process depends on your city or ward.
Typical Setup Process
You usually:
- call the local waterworks bureau
- use the city's online form or app if available
- provide address and move-in date
- confirm your name and contact number
In Tokyo, for example, the Waterworks Bureau takes applications by phone on 0570-091-100 or 03-5326-1101 between 8:30 and 20:00, or 24 hours a day through its online service, ideally three to four days before you move in. No visit is required. The one thing to check is the shut-off valve (止水栓) inside the property: if it was closed for the previous tenant, you may have to open it by hand before the taps work.
Sometimes the Landlord Has Already Arranged It
In some buildings, especially smaller rentals or certain managed properties, water may be partly handled through the landlord or building management. That is why your first question should always be: Do I need to set this up myself?
Typical Water Bill
Tokyo water is billed every two months. A single person generally falls in the ¥2,000–¥3,000 per month range, and the sewer charge is included on the same bill.
Good News
Water is usually the least stressful utility. There is rarely a complex choice of provider, and the activation process is often straightforward.
Internet (インターネット): The Most Complex Utility
Internet is where many newcomers miscalculate. Gas is urgent, but internet requires the most planning.
If you work remotely, study online, game heavily, or rely on video calls, do not leave this until after move-in.
Why Internet Takes Longer
Internet setup can depend on:
- building wiring compatibility
- whether fiber is already installed to the room
- landlord approval for installation work
- provider availability in your exact building
- technician scheduling
That is why the best advice is to start comparing 2 to 4 weeks before move-in if possible.
The Three Main Internet Options
1. Home WiFi Router (ホームルーター)
This is the fastest low-hassle option for many people.
How it works:
- provider sends you a plug-in router
- no installation visit needed
- usable almost immediately after delivery
Typical use case:
- short to medium stay
- people who want setup simplicity
- renters who cannot wait weeks for fiber
Typical speed range:
- often around 100 to 300 Mbps in real-life use, though it varies widely
Good fit for most solo residents who want predictable setup without drilling or construction.
2. Fiber Optic (光回線)
Fiber is usually the fastest and most stable long-term option.
Advantages:
- often 1 Gbps or more on paper
- better stability for work, gaming, and heavy uploads
- strong long-term value if you will stay a while
Disadvantages:
- often requires an installation visit
- activation may take 2 to 8 weeks
- some buildings restrict or complicate installation
Common names people encounter include NTT Hikari, NURO Hikari, and au Hikari, though availability varies heavily by address.
3. Pocket WiFi
Pocket WiFi is useful as a temporary bridge while waiting for a better home connection. It is portable and flexible, but usually not ideal as a permanent heavy-use solution.
Best use cases:
- first month after moving
- backup internet for travel
- short-term residents avoiding full installation
Expect around ¥3,000–¥4,500 a month, with a data cap on cheaper plans. It is also the only one of the three you can cancel by post without a technician appointment.
Contracts, Cancellation Fees, and English Support
Contract Length
Many Japanese internet plans still use 2-year contract structures or equivalent promotional periods. That means the cheapest headline monthly price may come with:
- cancellation fees if you leave inside the first year or two (commonly ¥4,000–¥5,000, sometimes more for the discount clawback)
- device return conditions
- point or cashback rules
- price increases after the initial campaign period
If your stay in Japan is shorter than the contract, a home router or pocket WiFi on a monthly contract is usually cheaper than fiber plus a cancellation fee. Work out the total cost of the whole period you will actually be in the apartment, not the monthly headline.
Compare Before Committing
Price-comparison sites such as kakaku.com are commonly used in Japan, but even if you compare there, always verify the actual provider terms carefully before signing.
English Support
Some major telecom companies and resellers offer English-language customer support, but availability differs by product and region. If your Japanese is limited, choosing a provider known for English support can be worth slightly higher monthly cost.
Suggested Timeline: What to Do and When
| Timing | Utility | What to do |
|---|---|---|
| 2–4 weeks before move | Internet | Compare home router vs. fiber, check building compatibility |
| 1–2 weeks before move | Gas | Book activation appointment |
| 1 week before move | Electricity | Submit start request online or by phone |
| 1 week before move | Water | Contact city water bureau or confirm landlord handling |
| Move-in day | Gas | Be home for technician visit |
| First week after move | Internet | Confirm activation, test speed, install equipment |
This timeline keeps you from solving everything in a panic after you already have boxes on the floor.

What to Prepare Before Calling
Keep these details in front of you:
- exact address in Japanese if possible
- apartment name and room number
- move-in date
- your phone number
- meter number or customer number from any card left in the apartment
- preferred payment method
- Residence Card or ID for in-person checks
If your Japanese is limited, write the information on paper first so you can read it calmly during the call.
Moving Day Checklist
On move-in day, confirm the following:
- electricity works in every room
- hot water is available or gas appointment is scheduled
- water runs normally from taps
- WiFi equipment has been delivered if expected
- you know where the utility notices or meter labels are located
- you have contact numbers for emergency service or management

Frequently Missed Details
A few small details cause oversized problems:
Meter Numbers
Many providers ask for a meter number. If the apartment has old utility stickers, cards, or labels near the entryway, kitchen, or meter box, take photos before you call.
Name Formatting
Use the same spelling of your name across your lease, Residence Card, and utility contracts where possible. Mixed romanization or middle-name formatting can create billing confusion.
Internet Installation Approval
Do not assume a technician can freely drill or access shared building equipment. Some landlords require explicit approval before installation work.
Temporary Internet Backup
If you work online and fiber activation will be slow, arrange a stopgap such as pocket WiFi or a home router before move-in rather than after your first failed video meeting.
Final Takeaway
Setting up utilities in Japan is manageable once you know the order of priority. Gas needs advance scheduling, electricity is usually easy, water is usually municipal, and internet needs the longest planning horizon.
If you confirm provider details with your landlord early, prepare a simple phone script, and treat internet as a separate project rather than a last-minute chore, you can avoid the two classic move-in disasters: no hot water and weeks without decent internet.
