日本搬家后生活基础设施开通清单：电、燃气、自来水和网络

最后确认: 2026-05-13

搬进日本公寓时，如果只想着钥匙和家具，第一周很容易混乱。电力有时可以先打开断路器使用，燃气通常需要预约开栓，水道要看当地水道局，网络则必须先确认建筑物可用线路。

办理顺序: 最安全的顺序是先电力，再预约燃气开栓，然后办理水道开始或停止，最后签网络。不要把客户编号、仪表编号或供给地点特定编号直接告诉突然上门的销售人员。

需要准备

• 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. 电力：入住前申请，之后再比较套餐

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. 燃气：预约开栓上门确认

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. 水道：通过当地水道局办理

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. 网络：先确认建筑线路限制

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.

需要避开的合同陷阱

• 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.
