How to send a fax to Japan

Why fax to Japan?

O Japão tem uma das taxas de utilização de fax mais elevadas do mundo. Empresas, repartições públicas, hospitais, hotéis e até muitas pequenas lojas continuam a recorrer ao fax para encomendas, reservas, candidaturas e correspondência oficial. Em muitas organizações japonesas, o fax é considerado mais formal e mais fiável do que o email, sobretudo para documentos que ostentam uma assinatura ou um selo da empresa (hanko).

Se está a fazer negócios com uma empresa japonesa, a candidatar-se a uma instituição japonesa ou a comunicar com uma repartição pública no Japão, ter um número de fax na página de contactos é a norma, não a exceção.

Tips for faxing to Japan

A few things to keep in mind when faxing to Japan:

• Business hours: Japanese offices typically work Japan Standard Time (UTC+9). Schedule around the recipient's local day if you are overseas.
• Drop the leading zero: remove the first 0 from area codes such as 03 or 06 when entering the number internationally.
• Use a cover sheet: include the recipient company, department, person name, and your contact details.
• Use PDF for best quality: official forms, scans, and signed documents fax more clearly when converted to a clean PDF before upload.
• Japanese text is fine: upload a PDF with Japanese characters and unofax will transmit it as rendered.

Common Japan fax situations

These are the kinds of local workflows where a fax number can still be the requested channel:

• Business confirmations: Japanese companies may still request faxed order forms, booking confirmations, and signed approvals.
• Government and school paperwork: public agencies and educational institutions can use fax for applications and supporting documents.
• Clinic and hotel forms: healthcare providers and accommodation operators may prefer faxed forms because staff workflows already support them.
