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.
