"Moving into your new apartment only to find you can't take a hot shower on the first night" — this isn't a joke, but a very common mistake for people starting their life in Tokyo. While electricity can usually be turned on simply by flipping the breaker, gas absolutely requires an in-person safety check by a technician before it can be used. During peak moving seasons, appointments fill up fast, and you might have to wait several days without hot water. In this guide, we outline a realistic utility setup schedule, highlight payment options, and share practical ways to keep your monthly fixed costs down.
Your experience living in Tokyo depends heavily on the neighborhood you choose. For example, if you are looking for an affordable and convenient area along the Chiyoda Line, check out our guide on Why Kita-Ayase is a Hidden Gem for First-Time Renters in Tokyo.
Step-by-Step Utility Activation & Saving Tips
Step 1: Choosing Energy Providers & Saving with "Set Discounts"
Unlike in the past, Japan's electricity and city gas markets are fully deregulated, meaning you can choose your own providers. Signing up for separate companies is a missed opportunity. The easiest and most effective way to lower your bills is to bundle your electricity and gas with a single provider. This automatically applies a monthly discount to your base rate or usage charges.
1. Standard Choices for Bundling in Tokyo
For most single residents and expats starting out in Tokyo, there are two primary options:
- Bundling under Tokyo Gas: This is the absolute classic. It automatically qualifies you for their "Gas and Electricity Set Discount" and consolidates your monthly bills into one, making budget tracking effortless. If you are new to Japan and want to avoid complex paperwork, we recommend starting with this reliable option.
- Alternative Power Companies (Shin-Denryoku): If you have specific needs—such as heavy nighttime electricity use or wanting to link utilities to your mobile phone carrier—you can opt for alternative providers. However, for a single person with average energy usage, the savings difference compared to Tokyo Gas is minor. Prioritizing ease of setup is usually the smarter choice.
2. What You Need & The Gas Activation "Trap"
Applying takes about 10 minutes on the provider's website. You will need your new address, full name, email address, and your payment details (credit card or bank account). Most major providers, including Tokyo Gas and TEPCO, offer English online applications or bilingual telephone support, making the process smooth for international residents.
The most critical thing to keep in mind is that gas activation absolutely requires your physical presence (safety check) at the apartment.
While electricity and water are usually active the moment you arrive, gas cannot be turned on until a licensed technician visits in person. This is a mandatory safety measure to inspect appliances and check for gas leaks. The procedure takes about 15 to 20 minutes. As soon as your move-in date is locked in, book a time slot online that matches when you plan to be at the apartment. Slots fill up extremely quickly during the peak moving seasons of spring (February to April) and autumn (September to October).
Step 2: Registering Water with the Tokyo Metropolitan Waterworks Bureau
Water services in Tokyo's 23 wards and most of the Tama area are managed entirely by the Tokyo Metropolitan Waterworks Bureau (東京都水道局). Since there are no private water providers to choose from, you simply register directly with them.
1. How to Submit Your Water Application
The easiest way is to apply online through the Tokyo Metropolitan Waterworks Bureau website or their official mobile app, both of which support English. Submitting your application at least three days before your move ensures you will have running water the moment you turn on the tap.
If you forgot to apply and need running water immediately, call their Customer Service Center at 03-5326-1101 (available Monday to Saturday, 8:30 AM to 8:00 PM). They offer English-speaking assistance. Unlike gas, there is no need for a technician to visit inside your apartment, so you do not need to be present for the water activation.
2. Payment Options: Why Bank Transfers and Credit Cards are Best
Water bills are issued once every two months. You can pay using a credit card, automatic bank transfer, or at any convenience store.
For payment methods, international residents have several convenient options:
- Convenience Store (Conbini) Cash Payments: If you don't have a Japanese bank account or credit card yet, you can pay using the paper billing slip (払込票, haraiomisho) sent to your mailbox. Simply hand the slip to the cashier at any 7-Eleven, Lawson, or FamilyMart and pay in cash.
- Credit Card Auto-pay: You can register your credit card online to automate payments and collect points.
- Automatic Bank Transfer (Koza Furikae) Discount: Switching your payment method to automatic bank transfer grants you a flat discount of 55 JPY (including tax) per bill. If you aren't focused on credit card points, setting up bank transfers is a reliable, hands-off way to save.

Step 3: Internet Setup & Smart Mobile Bundles
A reliable home internet connection is essential for remote work and streaming. However, many people treat internet setup like water or electricity, only to find themselves offline for weeks after moving in.
1. When to Apply for Fiber-Optic (Hikari) & Carrier Discounts
Setting up a new fiber-optic connection usually requires a physical installation by a technician. Timing is key here. During peak seasons (February to April), installation slots book out, and you may wait one to two months to get connected. As soon as your apartment application is approved and the lease is signed, making this application should be your top priority.
When choosing an internet provider, look for bundles that match your mobile carrier. Major Japanese carriers like docomo, SoftBank, and au offer discounts of up to 1,100 JPY per month per mobile line when paired with a compatible home fiber line. This discount can also apply to family members as well, helping you shave down your monthly bills.
2. Skipping the Wait: Home Routers as a Quick Solution
If a physical installation takes too long or isn't supported by your building, a "Home Router" (such as docomo home 5G or SoftBank Air) is a practical alternative. These devices plug directly into any standard wall outlet and connect via cellular networks, providing instant Wi-Fi without any construction. While raw speeds may not match fiber, the instant setup is incredibly convenient for those who need to get online immediately.
Once you move in, managing apartment humidity and utilizing your air conditioner's dehumidifying functions correctly is another important step.
