How to set up electricity and water in Tokyo: A complete guide for new residents

The first night in a Tokyo apartment should feel like arrival, not disruption. Yet thousands of residents each year face dark rooms and cold showers because utility activation requires more than turning a key. Tokyo’s electricity, gas, and water systems operate independently, each demanding separate applications, different timelines, and specific documentation. Understanding these procedures before your move-in date transforms what could be a frustrating experience into a seamless transition.

Understanding Tokyo’s utility infrastructure

Tokyo’s utility services operate through distinct systems. Electricity and gas have multiple competing providers since market deregulation, while water remains under municipal control through the Tokyo Metropolitan Bureau of Waterworks. This structure means residents handle three separate applications, each with its own requirements and activation timeline.

The Tokyo Metropolitan area covers 23 special wards (特別区) plus suburban cities, and utility providers vary by location. Most central Tokyo apartments in areas like Minato (港区), Shibuya (渋谷区), and Chiyoda (千代田区) fall under TEPCO for electricity infrastructure and Tokyo Gas for gas lines, though residents can now choose alternative providers for billing and service.

According to data from Tokyo’s utility providers, the peak moving season runs from mid-March through early April, with March 28th marking the highest volume day in 2026. Applications submitted during this period may face delays, making early submission essential.

Setting up electricity in your Tokyo apartment

Choosing an electricity provider

While TEPCO (Tokyo Electric Power Company) owns the infrastructure across most of Tokyo, deregulation allows residents to select from dozens of competing providers. The physical connection remains identical regardless of provider choice—only billing and customer service differ.

Major electricity providers in Tokyo include:

  • TEPCO Energy Partner: The traditional provider with the most extensive Japanese and English support
  • Tokyo Gas: Offers bundled electricity and gas contracts with discount rates
  • Rakuten Energy: Integrates with Rakuten points system
  • SoftBank Denki: Provides discounts for SoftBank mobile customers
  • ENEOSでんき: Offers competitive rates for high-usage households

For most residents, selecting TEPCO or Tokyo Gas simplifies the process, particularly when bundling services. According to Tokyo Gas, bundled electricity and gas contracts save approximately ¥2,000-3,000 monthly compared to separate provider arrangements.

The electricity application process

Electricity activation requires no technician visit in most cases. Tokyo apartments include a main breaker (ブレーカー) that residents switch on themselves upon move-in.

Step-by-step electricity setup:

  • Locate your customer number: Found on a card or sticker near the breaker panel, typically labeled “お客様番号” (customer number). This 10-13 digit identifier links your apartment to the electrical meter.
  • Submit your application: Contact your chosen provider 3-4 days before your move-in date. Applications accept online, by phone, or occasionally by postal card (often left in the apartment by previous residents).
  • Provide required information:
  • – Full name (as it appears on residence card)

    – New address with apartment number

    – Move-in date

    – Customer number from breaker panel

    – Phone number

    – Preferred payment method

  • Activate power on move-in day: Enter your apartment, locate the breaker panel (usually in the entryway), and flip the main breaker switch. Power activates immediately.
  • Confirm service: Most providers send confirmation within 24-48 hours via mail or email.
  • TEPCO and major providers offer English-language phone support, though hours are limited. The TEPCO English line operates weekdays 9:00-17:00 at 0120-995-113. Online applications through provider websites often include English interfaces, making them the most efficient option for non-Japanese speakers.

    Electricity costs in Tokyo

    Monthly electricity bills vary significantly based on apartment size, season, and usage patterns. Tokyo uses a tiered pricing system where rates increase with consumption.

    Typical monthly electricity costs (2026 rates):

    • Studio apartment (20-30㎡): ¥3,000-5,000
    • 1-bedroom apartment (40-50㎡): ¥5,000-8,000
    • 2-bedroom apartment (60-80㎡): ¥8,000-12,000
    • 3-bedroom apartment (80-100㎡): ¥12,000-18,000

    Summer (July-September) and winter (December-February) bills typically run 30-50% higher due to air conditioning and heating usage. TEPCO’s standard rate structure in 2026 charges approximately ¥20-30 per kWh depending on consumption tier, plus a basic monthly fee of ¥800-1,200.

    Gas service activation in Tokyo

    Understanding Tokyo’s gas system

    Tokyo uses city gas (都市ガス), a natural gas system delivered through underground pipes, distinct from propane (LPガス) common in rural areas. Gas service requires a technician visit for both activation and deactivation, making advance scheduling critical.

    Tokyo Gas dominates the market with approximately 70% market share across central Tokyo, though residents can now choose alternative providers like Nicigas, Toho Gas, or bundled services from electricity companies.

    The gas activation process

    Unlike electricity, gas activation demands a scheduled appointment. A licensed technician must physically inspect the gas meter, check for leaks, and demonstrate proper appliance operation.

    Step-by-step gas setup:

  • Apply 3-7 days before move-in: Gas appointments fill quickly, especially during peak moving season. Submit applications at least one week in advance to secure your preferred time slot.
  • Contact your provider: Tokyo Gas accepts applications online, by phone (0570-002211 for Japanese, 03-6735-8787 for English), or through their mobile app.
  • Provide required information:
  • – Full name and contact phone number

    – New address with apartment number

    – Move-in date and preferred appointment time

    – Gas meter number (if available, found on the meter box)

    – Payment method preference

  • Schedule the appointment: Morning slots (9:00-12:00) and afternoon slots (13:00-15:00 or 15:00-17:00) are available. Someone must be present during the entire appointment window.
  • Technician visit: The appointment typically lasts 20-30 minutes. The technician will:
  • – Unlock and inspect the gas meter

    – Check all gas connections for leaks

    – Test each gas appliance (stove, water heater, heating)

    – Explain safety procedures and emergency shut-off locations

    – Provide documentation and emergency contact information

  • Confirm operation: Before the technician leaves, test all gas appliances yourself to ensure proper function.
  • Tokyo Gas reports that 95% of scheduled appointments occur within the designated time window, though delays of 30-60 minutes can occur during peak season. The service carries no installation fee for standard activation.

    Gas costs in Tokyo

    Gas bills fluctuate significantly with season and usage patterns, particularly for apartments using gas heating and hot water systems.

    Typical monthly gas costs (2026 rates):

    • Studio apartment: ¥2,500-4,000 (summer), ¥4,000-7,000 (winter)
    • 1-bedroom apartment: ¥3,500-5,500 (summer), ¥6,000-10,000 (winter)
    • 2-bedroom apartment: ¥4,500-7,000 (summer), ¥8,000-14,000 (winter)
    • 3-bedroom apartment: ¥6,000-9,000 (summer), ¥12,000-20,000 (winter)

    Tokyo Gas pricing in 2026 averages ¥160-180 per cubic meter depending on consumption volume, plus a basic monthly fee of approximately ¥750. Winter heating can triple summer baseline costs, particularly in older apartments with less insulation.

    Water service setup in Tokyo

    Tokyo’s waterworks system

    Water service operates through municipal bureaus rather than private companies. The Tokyo Metropolitan Bureau of Waterworks (東京都水道局) serves the 23 central wards, while suburban cities like Musashino (武蔵野市) or Mitaka (三鷹市) operate independent systems.

    Water service begins immediately upon move-in—valves remain open between tenants. Residents must notify the waterworks bureau to transfer billing responsibility, but water flows regardless of application status.

    The water application process

    Water applications prove simpler than electricity or gas, requiring no appointments or technician visits. However, delayed applications result in bills sent to the previous resident or property management company, creating administrative complications.

    Step-by-step water setup:

  • Locate your customer number: Found on the water meter box (usually in a hallway or exterior wall) or on documentation left by the previous resident. The number format is typically “お客様番号” followed by 8-9 digits.
  • Submit your application: Contact the Tokyo Metropolitan Bureau of Waterworks within 3-4 days of move-in. Applications accept online through their website, by phone (03-5326-1100 for Japanese, 03-5326-1101 for English), or by postal card.
  • Provide required information:
  • – Full name and contact information

    – New address with apartment number

    – Move-in date

    – Water meter customer number

    – Previous address (if within Tokyo)

    – Preferred payment method

  • Confirm service: The bureau sends confirmation and your first bill within 2-3 weeks. Billing occurs every two months in Tokyo, unlike monthly electricity and gas bills.
  • The Tokyo Metropolitan Bureau of Waterworks provides English-language support on weekdays 8:30-17:15. Their website offers application forms in English, Chinese, and Korean, making the process accessible for international residents.

    Water costs in Tokyo

    Tokyo water bills combine water supply charges with sewage treatment fees, both calculated based on meter readings taken every two months.

    Typical bimonthly water costs (2026 rates):

    • Single resident: ¥2,500-4,000
    • Two residents: ¥4,000-6,000
    • Three residents: ¥5,500-8,000
    • Four residents: ¥7,000-10,000

    Tokyo’s water pricing uses a tiered structure starting at approximately ¥210 per cubic meter for the first 5㎥, increasing to ¥350+ per cubic meter for usage above 30㎥. Average single-person consumption runs 8-10㎥ per two-month billing period.

    Bundled utility contracts and cost savings

    Tokyo’s deregulated energy market enables bundled contracts combining electricity and gas under a single provider. These arrangements simplify billing and typically offer discount rates.

    Advantages of bundled contracts:

    • Single bill: One payment covers both electricity and gas
    • Discount rates: Bundled contracts save ¥2,000-4,000 monthly compared to separate providers
    • Simplified customer service: One phone number for all energy-related questions
    • Streamlined applications: Submit one application for both services

    Tokyo Gas offers the most popular bundled option, providing both city gas and electricity with approximately 5-8% discount on combined usage. TEPCO offers similar bundling through partnerships with gas providers.

    Disadvantages to consider:

    • Less flexibility to optimize individual service rates
    • Contract terms may lock rates for 1-2 years
    • Switching providers later requires changing both services simultaneously

    For most residents, bundled contracts provide the best value and convenience. Single-person households with minimal usage may find marginal savings by optimizing each service separately, though the administrative complexity rarely justifies the minimal cost difference.

    Payment methods for utility bills in Japan

    Tokyo utilities accept multiple payment methods, each with distinct advantages:

    Automatic bank transfer (口座振替)

    The most common payment method among Japanese residents. Monthly charges withdraw automatically from your designated bank account, typically 1-2 days after the billing date.

    Setup requirements:

    • Japanese bank account
    • Bank account number and branch information
    • Personal seal (印鑑) or signature
    • Completed automatic transfer form (provided by utility company)

    Most providers offer ¥50-55 monthly discount for automatic bank transfer, adding up to ¥600-660 annual savings per utility service.

    Convenience store payment (コンビニ払い)

    Bills arrive by mail with a payment slip (払込票) accepted at any Japanese convenience store. Simply present the slip at the register and pay in cash. This method suits residents without Japanese bank accounts or those preferring manual payment control.

    Convenience store payment carries no additional fees but offers no discount. Payment must occur by the due date printed on the slip to avoid late fees.

    Credit card payment

    Most major providers now accept credit card payment, allowing automatic monthly charges. This method benefits international residents who haven’t yet established Japanese bank accounts and those collecting credit card points.

    Credit card payment typically carries no fees or discounts, making it cost-neutral compared to convenience store payment while offering automatic processing convenience.

    Online payment

    Providers increasingly offer online payment through their websites or mobile apps, accepting credit cards or direct bank transfers. This method provides flexibility and immediate confirmation.

    Required documentation and information

    Gathering necessary information before contacting providers streamlines the application process:

    Essential information for all utilities:

    • Full legal name (matching residence card)
    • New address with apartment number in Japanese format
    • Move-in date
    • Contact phone number
    • Previous address (if applicable)
    • Preferred payment method

    Service-specific requirements:

    • Electricity: Customer number from breaker panel
    • Gas: Preferred appointment date and time window
    • Water: Water meter customer number

    Payment setup documentation:

    • Bank account: Account number, branch name, account holder name
    • Credit card: Card number, expiration date, security code
    • Automatic transfer: Personal seal or signature authorization

    International residents should note that utility applications require a Japanese phone number. Providers will not accept foreign phone numbers for account registration, as billing and service notifications use Japan’s domestic SMS and phone systems.

    Timeline for utility setup

    Proper timing prevents service gaps and ensures smooth activation:

    Recommended application timeline:

    • 2 weeks before move-in: Research providers and decide on bundled vs. separate contracts
    • 1 week before move-in: Submit electricity and water applications
    • 5-7 days before move-in: Schedule gas technician appointment
    • Move-in day: Activate electricity breaker, meet gas technician at scheduled time
    • Within 3 days of move-in: Confirm water application if not completed earlier

    During Tokyo’s peak moving season (mid-March through early April), extend these timelines by 3-5 days. Gas appointments during this period may require booking 10-14 days in advance.

    Special considerations for international residents

    Language support

    Major providers offer varying levels of English support:

    TEPCO: English phone line (0120-995-113) weekdays 9:00-17:00, English website for applications
    Tokyo Gas: English phone line (03-6735-8787) weekdays 9:00-17:00, English website with limited functionality
    Tokyo Metropolitan Bureau of Waterworks: English phone line (03-5326-1101) weekdays 8:30-17:15, multilingual website

    Online applications generally provide the most comprehensive English interfaces, with phone support serving as backup for complex questions.

    Residence status requirements

    Utility providers require valid residence status in Japan. Applications request residence card information, and some providers verify status through the municipality registration system. Tourist visas do not qualify for utility contracts—apartments rented on tourist status typically include utilities in the rent with the landlord maintaining contracts.

    Property management company coordination

    Many Tokyo apartments, particularly in buildings managed by large companies, coordinate utility setup through the management office. When signing your lease, confirm whether:

    • The management company handles utility applications on your behalf
    • You must apply independently
    • Any specific providers are required or recommended for the building

    Some luxury buildings in areas like Roppongi (六本木) or Azabu (麻布) include utility coordination as part of their concierge services, eliminating individual application requirements.

    Common issues and solutions

    Gas appointment scheduling conflicts

    Gas activation requires someone present during the entire appointment window. If your move-in schedule conflicts with available appointment times, consider:

    • Authorizing a representative (friend, colleague, or property agent) to meet the technician
    • Requesting an early morning (9:00) or late afternoon (15:00-17:00) slot to minimize work disruption
    • Scheduling the appointment for the day after move-in if necessary, using electricity for essential needs overnight

    Tokyo Gas allows authorized representatives if you submit written permission in advance, though this adds administrative complexity.

    Missing customer numbers

    If your apartment lacks visible customer numbers for electricity or water meters:

    • Check documentation provided by your real estate agent or landlord
    • Contact the property management company
    • For electricity, providers can locate your account using your address and move-in date
    • For water, the bureau can identify your meter through property records

    Applications proceed without customer numbers, though processing may take 1-2 additional days.

    Payment method complications

    International residents often face challenges setting up automatic bank transfer before establishing Japanese bank accounts. Solutions include:

    • Begin with convenience store or credit card payment
    • Switch to automatic bank transfer once you open a Japanese account
    • Use credit cards that don’t charge foreign transaction fees if your card was issued overseas

    Most providers allow payment method changes at any time through their website or customer service line.

    Utility costs for budget planning

    Combining all three utilities, Tokyo residents should budget approximately:

    Monthly utility costs by apartment size (2026 estimates):

    | Apartment Size | Summer (Apr-Jun, Sep-Oct) | Winter (Nov-Mar) | Peak Summer/Winter (Jul-Aug, Dec-Feb) |

    |—————-|—————————|——————|—————————————|

    | Studio (20-30㎡) | ¥6,500-9,000 | ¥8,500-12,000 | ¥10,000-14,000 |

    | 1-bedroom (40-50㎡) | ¥9,500-14,000 | ¥12,500-19,000 | ¥15,000-23,000 |

    | 2-bedroom (60-80㎡) | ¥13,500-20,000 | ¥18,000-27,000 | ¥22,000-33,000 |

    | 3-bedroom (80-100㎡) | ¥19,000-28,000 | ¥26,000-39,000 | ¥32,000-48,000 |

    These estimates assume moderate usage patterns, standard appliances, and typical Tokyo climate conditions. Actual costs vary based on lifestyle, appliance efficiency, insulation quality, and personal comfort preferences.

    Water costs remain relatively stable year-round, while electricity and gas fluctuate significantly with heating and cooling demands. The bimonthly water billing cycle means one large payment every two months rather than monthly charges.

    Understanding your utility bills

    Tokyo utility bills arrive in Japanese with limited English translation. Key elements to identify:

    Electricity bill components:

    • 使用量 (shiyouryou): Usage amount in kWh
    • 基本料金 (kihon ryoukin): Basic monthly charge
    • 電力量料金 (denryoku ryou ryoukin): Usage-based charge
    • 燃料費調整額 (nenryouhi chousei gaku): Fuel cost adjustment
    • 再エネ賦課金 (sai-ene fukakukin): Renewable energy surcharge
    • ご請求金額 (go-seikyuu kingaku): Total amount due

    Gas bill components:

    • ご使用量 (go-shiyouryou): Usage in cubic meters (㎥)
    • 基本料金 (kihon ryoukin): Basic monthly charge
    • 従量料金 (juuryou ryoukin): Volume-based charge
    • ご請求額 (go-seikyuu gaku): Total amount due

    Water bill components:

    • 使用水量 (shiyou suiryou): Water usage in cubic meters
    • 上水道料金 (jousuidou ryoukin): Water supply charge
    • 下水道料金 (gesuidou ryoukin): Sewage treatment charge
    • 合計金額 (goukei kingaku): Total amount due (for two-month period)

    Most providers offer English bill explanations on their websites, and mobile apps increasingly provide translation features for bill comprehension.

    Stopping utility services when moving out

    Deactivating utilities when leaving your Tokyo apartment requires similar advance notice:

    Electricity and water: Contact providers 3-4 days before move-out to schedule final meter reading and billing. Both services stop automatically without technician visits.
    Gas: Schedule a technician appointment for your move-out date. The technician must physically lock the gas meter, requiring your presence or an authorized representative. Book this appointment 5-7 days in advance, particularly during peak moving season.

    Final bills calculate usage through your last day of residence. Providers typically mail final bills to your new address, or you can pay the final amount at a convenience store using the payment slip provided by the technician (for gas) or by mail (for electricity and water).

    Making utility setup seamless

    The difference between a smooth move-in and a complicated one often reduces to preparation timing. Tokyo’s utility systems operate efficiently once you understand their distinct requirements: electricity activates with a simple breaker switch, gas demands a scheduled technician visit, and water flows automatically while billing transfers through municipal registration.

    Starting applications one week before your move-in date, gathering necessary documentation in advance, and understanding the appointment requirements for gas service eliminate most complications. For residents in Tokyo’s central wards, the process takes approximately 30-45 minutes of total application time across all three services.
