日本搬家後生活基礎設施開通清單：電、瓦斯、自來水與網路

最後確認: 2026-05-13

搬進日本公寓時，如果只注意鑰匙和家具，第一週很容易出問題。電力有時能先打開斷路器使用，瓦斯通常需要預約開栓，自來水依各地水道局辦理，網路則要先確認建物可用線路。

辦理順序: 最安全的順序是先電力，再預約瓦斯開栓，接著辦理水道開始或停止，最後簽網路。不要把客戶編號、電表號碼或供給地點特定編號直接告訴突然上門的業務。

需要準備

• 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. 電力：入住前申請，之後再比較方案

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. 瓦斯：預約開栓到場確認

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. 自來水：透過當地水道局辦理

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. 網路：先確認建物線路限制

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.

需要避開的契約陷阱

• 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.
