일본 이사 후 전기·가스·수도·인터넷 개통 체크리스트

최종 확인: 2026-05-13

일본 아파트에 입주할 때 열쇠와 가구만 생각하면 첫 주가 복잡해집니다. 전기는 차단기를 올리면 사용 가능한 경우가 있지만, 가스는 보통 개전 예약과 입회가 필요하고, 수도는 지역 수도국 절차를 따르며, 인터넷은 건물 설비 확인이 먼저입니다.

처리 순서: 안전한 순서는 전기, 가스 개전 예약, 수도 시작 또는 정지, 인터넷입니다. 갑자기 방문한 영업사원에게 고객번호, 계량기 번호, 공급지점특정번호를 바로 알려주지 마세요.

준비할 것

• Address, room number and move-in date
• Contract holder name, phone number and email
• Electricity customer number, supply point ID or meter number
• Candidate times for the gas opening visit
• Water customer number if available, or the new address
• Building-compatible internet type: fiber, home router or pocket Wi-Fi

1. 전기: 입주 전 신청하고 나중에 요금제 비교

The Agency for Natural Resources and Energy says electricity switching usually requires details such as the customer number and supply point ID. Its guide gives standard examples of about 2 weeks when smart-meter replacement is needed and about 4 days when it is not. Your real start date still depends on the provider and building, so apply as soon as your move-in date is fixed.

2. 가스: 개전 입회 예약

Gas needs more scheduling than electricity. Tokyo Gas states in its foreigner-facing procedure page that attendance is required when starting gas service. A proxy may be possible, but the technician checks ignition and safety inside the home, so reserve a time that does not conflict with work or school.

3. 수도: 지역 수도국에서 처리

Water is handled by the local water bureau. Tokyo has an English page for starting and cancelling water service, but outside Tokyo you should check the city or local bureau website. Water is easy to forget, so put both the old-place cancellation and new-place start request in the same checklist.

4. 인터넷: 건물 제한을 먼저 확인

For internet, check the building before chasing the cheapest price. A room that supports fiber, a room better suited to a home router, and a room where pocket Wi-Fi is enough are different situations. GTN's official page describes mobile and internet services for foreign residents with multilingual support, but you should confirm building compatibility, installation work, contract period and cancellation terms before applying.

피해야 할 계약 함정

• Do not show meter slips or bills immediately to an unexpected salesperson.
• If someone says every resident in the building must switch, verify it with the management company or lease documents.
• When a plan is advertised as cheaper, check base fees, adjustment charges, contract period and cancellation terms.
• If you already signed something worrying, contact the 188 consumer hotline or a local consumer center.
