Japan has among the highest business FAX usage of any developed economy. While many countries have reduced their reliance on fax, Japan's corporate and government culture continues to treat FAX — written in uppercase, as it is in Japanese business contexts (ビジネスFAX) — as a primary document exchange channel. Construction companies, manufacturing firms, travel agencies, wholesale distributors, real estate agencies, and government ministries all use FAX as a routine part of daily operations.

Who uses FAX in Japan

National Tax Agency (国税庁)

The National Tax Agency (国税庁, Kokuzei-chō) accepts FAX submissions for certain tax-related correspondence, including responses to audit inquiries and specific filing supplements. Japanese tax administration involves a significant volume of paper-based processes, and FAX is recognised as a valid submission channel for many document types. Regional tax offices (税務署, zeimusho) throughout Japan publish FAX numbers for written enquiries, corrections, and supporting document submissions.

Ministry of Health, Labour and Welfare (厚生労働省)

The Ministry of Health, Labour and Welfare (厚生労働省, Kōsei Rōdōshō) and the agencies under its umbrella — including the Japan Pension Service (日本年金機構) and Hello Work employment offices — use FAX to receive claims, notifications, and documentation related to social insurance, labour standards, and employment programmes. Employers regularly FAX payroll-related notifications and employee status changes to these agencies. Hello Work offices in particular maintain active FAX lines for job-seeker and employer documentation.

Local city offices (市役所・区役所)

City offices (市役所, shiyakusho) and ward offices (区役所, kuyakusho) across Japan accept FAX for administrative applications and supporting documents. Residents and businesses use FAX to submit residency change notifications, certificate requests, and other administrative paperwork. This is particularly common in smaller municipalities where digital alternatives are limited, but even large city wards in Tokyo and Osaka maintain active FAX lines.

Real estate agencies (不動産会社) and corporate sectors

Japanese real estate agencies (不動産会社) use FAX heavily for property listings, contract negotiations, and tenancy documentation. The practice of "fax broadcasting" listings to prospective clients and partner agencies is still widespread. Beyond real estate, FAX remains standard in the construction (建設), manufacturing (製造), wholesale trade (卸売業), and travel agency (旅行会社) industries. Many purchase orders, delivery confirmations, quotation requests, and booking confirmations in these sectors are still processed by FAX.

FAQ

How do I format a Japanese fax number for international sending?

Remove the leading 0 from the area code. A Tokyo number written as 03-1234-5678 becomes 3-1234-5678 when Japan (+81) is selected. An Osaka number written as 06-1234-5678 becomes 6-1234-5678.

What are the +81 50 numbers used for?

Numbers beginning with 050 are IP telephony numbers, commonly used by virtual FAX lines, internet telephone services, and some businesses. They follow the same rule: drop the leading 0, so 050-XXXX-XXXX becomes 50-XXXX-XXXX when Japan (+81) is selected.

Can I send a FAX in Japanese (including kanji)?

Yes, as long as your document is saved as a PDF. Any text in the PDF — including Japanese characters (漢字, ひらがな, カタカナ) — is transmitted as-is. The recipient sees exactly what is in your PDF.

Can I fax to a Japanese government office?

Yes. Use the FAX number published on the specific ministry, agency, or local government office's official website. Most 税務署 (tax offices) and 市役所 (city offices) publish department FAX numbers on their official pages.

Why does Japan still use FAX so much?

Japan's sustained FAX culture reflects a combination of established business etiquette, the role of hanko (印鑑) seals in document authentication, strong attachment to paper-based record-keeping, and the historical adoption of FAX before internet infrastructure matured. Many industries have built entire operational workflows around FAX, and transitions to digital alternatives have been incremental.

How long does a FAX to Japan take?

Most deliveries complete within 2–5 minutes. If the recipient line is busy, the service retries automatically.
