How to send a fax to Japan

Why fax to Japan?

Japan has one of the highest rates of fax usage in the world. Businesses, government offices, hospitals, hotels, and even many small shops still rely on fax for orders, reservations, applications, and official correspondence. In many Japanese organizations, fax is considered more formal and more reliable than email — particularly for documents that carry a signature or a company seal (hanko).

If you are doing business with a Japanese company, applying to a Japanese institution, or communicating with a government office in Japan, having a fax number on their contact page is the norm, not the exception.

What you need

To send a fax to Japan with unofax you need four things:

• Your document: PDF, Word, image, or any supported file. PDF gives the best results.
• The Japanese fax number: Japan's country code is +81. Drop the leading zero from the area code. A Tokyo number written 03-1234-5678 in Japan becomes +81 3 1234 5678 when you send from abroad.
• A payment method: credit card, debit card, Apple Pay, or Google Pay.
• Your email address: for delivery confirmation and proof of receipt.

No account, no subscription, no fax machine required.

Step by step

Sending a fax to Japan with unofax takes about two minutes:

• Upload your document: drag and drop or tap to select your file.
• Select Japan and enter the fax number: choose Japan from the country list. Type the number without the leading zero. unofax adds the +81 country code automatically.
• Enter your email: provide your email address for delivery confirmation and proof of receipt.
• Preview: check each page in the preview. Add a free cover sheet if the recipient requires one.
• Pay: the per-page price is shown upfront. Pay with card, Apple Pay, or Google Pay.
• Done: your fax is sent immediately. You receive a delivery confirmation once the receiving machine acknowledges receipt.

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.

Common questions

Quick answers about faxing to Japan:

• What does a fax number in Japan look like? — A Japanese fax number has 10 digits including the leading 0, usually written with hyphens: 03-1234-5678 in Tokyo, 06-1234-5678 in Osaka. Other common area codes are 045 (Yokohama), 052 (Nagoya), 075 (Kyoto), and 092 (Fukuoka). To send from outside Japan, drop the 0 and add +81, so 03-1234-5678 becomes +81 3 1234 5678. Toll-free 0120 numbers usually cannot be reached from abroad, so ask for a regular number if that is all you have.
• How long does delivery take? — Most faxes are delivered within one to three minutes. Delivery time depends on the number of pages and the speed of the receiving machine.
• Can I send Japanese-language documents? — Yes. Use a PDF for best results, especially when the document contains Japanese text or stamps.
• How much does it cost to fax to Japan? — unofax charges a flat per-page rate. The price in your local currency is displayed before you pay. There are no subscriptions, setup fees, or hidden charges.
