Written by | Jun 11, 2026 2:51:00 PM

Quick Summary

  • Language Support: Choose utility providers with dedicated English customer lines or use specialized expat bundle services like GTN to bypass language barriers.
  • Gas Safety Inspection: Unlike electricity and water, gas activation strictly requires your physical presence (or an authorized representative) at the property for safety tests.
  • Paying Bills: If you don't have a Japanese bank account yet, you can pay your monthly utility bills in cash at any convenience store using mailed payment slips.

Moving to Tokyo is an exciting adventure, but setting up your new apartment's utilities—electricity, gas, water, and internet—can be daunting. Language barriers, complex forms, and unique local regulations often surprise expats. This comprehensive guide breaks down the procedures step-by-step and shares expert money-saving tips to get you settled smoothly.

Step-by-Step Utility Setup and Savings Guide for Expats

Step 1: Electricity & Gas Setup (And How to Bundle for Discounts)

Japan's electricity and gas markets are fully liberalized. This means you are not forced to use the traditional regional monopolies (TEPCO and Tokyo Gas) and can choose from various competitive providers.

1. Choosing Your Provider

  • Traditional Giants (English Support Available): TEPCO (electricity) and Tokyo Gas (gas) both offer dedicated English telephone customer services, making them a safe choice for newcomers.
  • Expat-Focused Bundles (Recommended): Services like GTN (Global Trust Networks) offer bundled utility services (electricity, gas, and water) with support in multiple languages. They handle the applications on your behalf, so you do not have to struggle with Japanese forms.
  • Bundling for Savings: Most companies offer a "Gas and Electricity Bundle Discount." Bundling can save you between 2,000 to 10,000 yen annually depending on your usage.

2. Crucial Timeline & Rules

  • Application Timeline: Submit your application online at least 1 week (minimum 3 days) before your move-in date.
  • The Gas Safety Check (Presence required): While electricity and water can be turned on remotely, **the gas company must send a technician to test the gas appliances inside your home**. Someone must be physically present in the apartment for this safety check. Without it, you will not have hot water.
  • LP Gas vs. City Gas Warning: Make sure you know whether your apartment uses City Gas (Toshi Gas) or Liquid Propane Gas (LP Gas/LPG). LP gas appliances and city gas appliances are **not compatible**. Using the wrong appliance is extremely dangerous.

Step 2: Water Service Activation (Tokyo Metropolitan Waterworks Bureau)

Unlike electricity and gas, water is managed by the local government, so there is no competition. In Tokyo's 23 wards, your service provider will be the Tokyo Metropolitan Waterworks Bureau.

1. How to Apply

  • Online Application (English available): You can easily apply on the Tokyo Waterworks website using their English portal. Apply at least 3 to 4 days before moving in.
  • Payment Methods: Until you set up a Japanese bank account or credit card, you can pay using paper slips (Conbini barai) sent to your mailbox. Simply take the slip to any convenience store (7-Eleven, FamilyMart, Lawson) and pay in cash at the register.

Step 3: Internet Connection & Mobile Plans

Securing a high-speed internet connection is vital, but the setup process in Japan can be slow and bureaucratic.

1. Fixed Fiber-Optic Line (Hikari)

  • Installation Delay: Getting physical fiber optic lines installed can take anywhere from 3 weeks to 2 months, especially during peak moving seasons (March to April). Apply as soon as your rental contract is signed.
  • Smart Savings (Mobile Bundles): If you get fiber internet through your mobile carrier (e.g., Docomo, SoftBank, or au), you can get a "Mobile Set Discount," which reduces your family's smartphone bills by up to 1,100 yen per phone every month.

2. Pocket Wi-Fi & Home Routers (Instant Alternatives)

If you cannot wait weeks for an installation, or if your landlord doesn't allow drilling for cables, consider a plug-and-play Home Router (such as SoftBank Air) or rent a Pocket Wi-Fi device from expat-friendly services like Sakura Mobile or Mobal. These do not require installation and can be active on day one.

Frequently Asked Questions (FAQ)

Q. What should I do if the electricity doesn't work on my move-in day?

A. Locate the main breaker panel (usually near the entrance or in the kitchen) and flip all the switches to the "ON" (入) position. If the power still doesn't turn on, contact your electricity provider immediately or call the regional grid operator (TEPCO Power Grid in Tokyo).

Q. Can someone else stand in for my gas safety check?

A. While many gas providers accept a proxy (like a family member, roommate, or real estate agent) to facilitate the check, some companies or special plans strictly require the contract holder's presence. Please verify with your gas provider beforehand. The person present must be inside the apartment to let the technician in and acknowledge the safety instructions.

Q. How do I know if my stove is compatible with City Gas or LP Gas?

A. Look at the product label on your gas stove. It will clearly state "都市ガス用" (for City Gas, e.g., 12A/13A) or "LPガス用 / プロパンガス用" (for LP Gas). Do not connect a City Gas stove to an LP Gas line, or vice versa, as it is a major fire and safety hazard.
