When moving day arrives for your first solo apartment, the most stressful situation is having no electricity, gas, or water. Electricity typically becomes available on moving day with just a notification, but gas requires an in-person appointment, and you may not be able to use it on the same day without advance booking. This article explains all the necessary procedures for opening electricity, gas, and water so you can start living comfortably from day one.
To begin using electricity, contact the electricity provider that serves your new address (or choose a new electricity company).
How to Contact
When to Contact
Required Information
In most cases, electricity will automatically be connected once you notify the provider, and you can use it from moving day. Properties with smart meters are especially simple to set up.
If You Don't Have a Smart Meter
Since deregulation in 2016, you can choose any electricity provider. Moving is the perfect time to switch.
| Type | Features | Best For |
|---|---|---|
| Major Electric Companies | Stable, excellent support | Those prioritizing reliability |
| New Energy Companies (gas bundles, etc.) | Cheaper with gas combo | Those switching gas too |
| Renewable Energy | Environmentally focused | Eco-conscious customers |
| Point-Linked Plans | Points for specific services | Heavy users of specific services |
Even with the same usage, different companies may charge 500–2,000 yen per month differently. Use an "electricity rate comparison site" to compare plans that match your usage before deciding.
Unlike electricity, in-person attendance is required when opening a gas account. If you contact the company the day before or on moving day, their schedule may be fully booked and they may not be able to help you that day.
When to Contact: Book your appointment 1–2 weeks before move-in day

Required Information
If You Can't Attend
Most companies only operate on weekday daytime. If you can't attend due to work, you can take time off for moving, ask a family member, or have a friend attend on your behalf.
| Item | City Gas | Propane Gas (LPG) |
|---|---|---|
| Cost | Generally cheaper | More expensive (free pricing) |
| Availability | Only in areas with infrastructure | Available nationwide |
| Switching | Deregulated since 2017 | Deregulated but with restrictions |
| Service Disruptions | Area-wide outages possible | Individual tank replacement |
Propane gas typically costs 1.5–2 times more than city gas for the same amount of energy. It's important to confirm which type of gas your apartment has when choosing where to live.
To start using water, contact the water department (water and sewage bureau) in your new city or ward.
How to Contact
When to Contact: A few days before move-in day up to move-in day
Like electricity, water service usually starts as soon as you notify the department. In most cases, you just need to open the main valve and water flows immediately.
If you forget to stop water service at your old apartment after moving, you'll continue paying the base charge even though you're not using it. Make sure to notify the water department in your previous location as well.
To set up an internet connection when you move, you need to apply in advance.
Time to Connection After Application
Until your service is installed, use your phone's mobile hotspot or a portable Wi-Fi device.
| When | What to Do |
|---|---|
| 2 weeks before move-in | Book gas appointment, apply for internet connection |
| 1 week before move-in | Apply to start electricity, contact water department to start service |
| Move-in day | Attend gas appointment, check main breaker, open water main valve |
| After move-in | Stop electricity, gas, and water service at your old place |
To have comfortable utilities from your first day, the most important step is booking your gas appointment 2 weeks before moving. Electricity and water can usually be set up on moving day, but gas won't work without an advance appointment. By starting your utility procedures early alongside your moving plans, you can enjoy a comfortable move-in day from the start.
