Utilities Guide 2025: Electricity, Gas, Water & WiFi Setup

Once you secure an apartment, step 1 is setting up your lifelines: Electricity, Water, and Gas. Since Japan deregulated energy, you have the right to choose your provider for better rates!

1. ELECTRICITY (DENKI) - DITCH TEPCO

Most people default to TEPCO (Tokyo Power). But their rates are pricey. Look into "Shin-Denryoku" (New Power companies):

  • Looop Denki: No base fee (Kihon Ryoukin = 0). You only pay for exactly what you use. Excellent for people who are out at work all day.
  • Rakuten Denki: Earns Rakuten Points. If you shop online, this is a lifesaver.

2. GAS

There are two types:

  • Toshi Gas (City Gas): Underground pipes. CHEAP.
  • LP Gas (Propane): Big tanks outside the house. EXPENSIVE (1.5 - 2x the price).

House Hunting Tip: Always check which gas type the apartment uses. LP Gas bills in winter can easily exceed 15,000 JPY!

3. INTERNET (WIFI) - THE CONTRACT TRAP

  • Pocket WiFi: Portable, no installation needed. Average speed. Great for short-term stays (1-2 years).
  • Fiber Optic (Hikari): Lightning fast. Requires installation (you need landlord permission to drill). Beware: Usually requires a strict 2-3 year contract with steep cancellation fines (~10,000-20,000 JPY).

Tip: Bundle! If you use YMobile or UQ Mobile for your phone, get their home internet (Softbank Air, UQ Wimax) for significant monthly discounts.

4. HOW TO APPLY

Most registrations are done online or via phone.

  • Water (Suido): Call the local Waterworks Bureau and inform them of your move-in date.
  • Gas: Requires an in-person appointment (Tachiai). A worker must visit your home to safely open the valve while you are present.

Life Utilities

CONCLUSION

Making smart choices (e.g., Toshi Gas + Looop Denki + bundled WiFi) can save you 30,000 - 50,000 JPY a year!
