Checklist de contas no Japão: luz, gás, água e internet ao mudar

Última verificação: 2026-05-13

Ao entrar em um apartamento no Japão, pensar só em chave e móveis não basta. A luz pode funcionar ao levantar o disjuntor, mas o gás normalmente exige agendamento, a água depende do órgão local e a internet precisa de checagem da infraestrutura do prédio.

Ordem rápida: A ordem segura é luz, agendamento do gás, água e depois internet. Não entregue número de cliente, número do medidor ou supply point ID a vendedores que aparecem sem aviso.

O que preparar

• 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. Luz: solicite antes da mudança e depois compare planos

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. Gás: agende a abertura com presença

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. Água: use o órgão local de água

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. Internet: confirme as limitações do prédio antes de assinar

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.

Armadilhas de contrato

• 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.
