Why Japan Still Uses Fax Machines in 2026?

Japan is internationally known for bullet trains, advanced robotics, sophisticated high-tech toilets, and precision manufacturing. That makes it genuinely surprising to many foreign visitors that fax is still a normal part of business and administrative life in Japan in 2026.

If email, PDFs, cloud services, online portals, APIs, and electronic signatures all exist, why not simply stop using fax?

The answer has little to do with Japan simply being old-fashioned. It has much more to do with the cost and difficulty of replacing an established network that already works. The strange thing about fax in Japan isn’t that better technology exists — it’s that replacing an old technology can sometimes cost more than continuing to use it.

How Common Is Fax in Japan in 2026?

According to industry data from the Communications and Information Network Association of Japan (CIAJ), the share of Japanese businesses reporting fax usage fell from roughly 49.7% in fiscal 2020 to about 37.9% in fiscal 2025 — a real decline, though far from disappearance.

Household data tells a similar story, but with a sharper generational divide. One widely cited 2024 household survey put overall fax ownership at around 24.6%, but that average hides a steep age gradient:

Age Group	Fax Ownership
People in their 20s	~0.9%
People in their 30s	~4.0%
People in their 40s	~13.1%
People aged 60 and older	Above 30%

In other words, fax in Japan today looks less like a universal habit and more like a technology still anchored in older households and specific corners of the business world — declining steadily, but not yet gone.

What Is Fax Still Used For?

In practice, fax tends to survive in specific, concrete corners of daily business life: purchase orders between companies, forms exchanged between small businesses, medical and healthcare paperwork, administrative documents, and reservations or applications at organizations that haven’t fully digitized.

Handwritten documents are a particularly useful example:

Traditional Fax Workflow	Digital Alternative
Write on paper → feed it into a fax machine → dial a number → send	Scan the document → create a PDF → name and save the file → open an email or portal → log in → attach it → select a recipient → send it

That’s not to say fax is always faster. But for a handwritten form moving between two people who already have a working relationship, fax can sometimes be the shortest path from one desk to another.

Didn’t the West Get Rid of Fax Years Ago?

In many ordinary offices across the US, UK, and similar markets, fax has a reputation as obsolete technology — replaced years ago by email attachments, secure email, online customer and supplier portals, cloud document systems, and electronic signatures.

For business-to-business data, more advanced systems go a step further. Electronic Data Interchange (EDI) and APIs — software interfaces that let two systems exchange information directly — don’t just send an image of a document; they transfer the underlying structured data itself. That can eliminate an inefficient chain: type information into a computer, print it, fax it, receive it as paper, and then manually re-enter it into another computer at the other end.

Given all that, it’s tempting to assume fax is essentially extinct in the West. But fax is not quite as dead there as it sometimes appears.

America and Europe Still Fax Too

Consider a few examples:

So Why Doesn’t Japan Just Switch?

This is really the heart of the matter, and a hypothetical example makes it concrete.

Imagine a small Japanese wholesaler with about 100 regular business customers. The existing workflow is simple: a customer fills out an order form, faxes it over, and an employee checks and processes it. It’s an old system, but everyone already knows how to use it — no new accounts, no compatible software, and no training required. The fax number already exists, and internal procedures are already built around it.

Now imagine replacing that with a web-based ordering system. The wholesaler would need to:

• Buy or build software, and configure it
• Integrate it with existing systems
• Notify every customer and create accounts
• Train employees and customers through the transition
• Rewrite internal procedures
• Handle customers who can’t or won’t switch
• Possibly run both systems side by side for a while

That bundle of costs and effort is what economists call switching costs.

There’s also a network effect at work: a communication system becomes more valuable because the people you need to reach already use it. If most of a company’s suppliers and customers still accept fax, that company can’t eliminate it without potentially inconveniencing the people it does business with.

This isn’t just theoretical. A 2024 survey of manufacturing-sector fax users who wanted to stop faxing found that the biggest obstacles included business partners still using fax (63.0%), a lack of an effective alternative tool (32.2%), and handwritten documents that fax handles more easily (30.3%).

Seen this way, the choice isn’t really old technology versus new technology. It’s a cheap system everyone already uses versus a better system that requires many of those users to change at the same time.

The Strange Logic of Fax: Inefficient but Rational

Here’s the paradox at the center of this topic: fax can be inefficient, yet keeping it can still be perfectly rational.

Now zoom out to the scale of an entire economy. If thousands of businesses each individually decide that migrating away from fax isn’t worth the cost, Japan as a whole can end up collectively stuck with manual data entry, paper handling, duplicated work, and fragmented systems. What makes sense for one company can become genuinely inefficient once thousands of companies make the same reasonable choice.

Is Fax Really More Secure?

A common belief, especially in some professional and healthcare contexts, is that fax is inherently more secure than email. That claim doesn’t really hold up under scrutiny.

Fax does avoid certain digital risks: it isn’t vulnerable to the phishing links or malicious attachments that target email inboxes, and a traditional fax machine doesn’t rely on an email password that could be compromised. But fax introduces its own risks — a misdialed number can send a sensitive document straight to a stranger, and faxed pages can sit unattended in an office tray where anyone walking by might see them.

Modern secure email, encrypted messaging, and properly configured online portals can be built to be at least as secure as fax, and often considerably more so. What fax genuinely offers isn’t necessarily superior security — it’s simplicity, familiarity, and broad compatibility.

Fax Doesn’t Always Mean a Fax Machine

It’s also worth clearing up a common assumption: using fax doesn’t necessarily mean owning a physical fax machine. Many organizations now send faxes from a computer through an internet-based or cloud fax service, which routes the document to the recipient’s fax endpoint. Incoming faxes can work in reverse, arriving as a PDF in an email inbox rather than curling out of a machine beside the telephone.

The practical upshot is that the physical fax machine may disappear well before fax itself does.

Will Japan Finally Abandon Fax?

So will fax eventually disappear from Japan? The trend line points that way. Business usage has already fallen from roughly 49.7% to about 37.9% over five fiscal years, and among younger households, ownership is already in the low single digits.

Several forces are pushing in the same direction: cloud software, online ordering systems, electronic signatures, digital invoicing, secure portals, EDI and APIs, workplace automation, generational turnover as older employees retire, and ongoing government and private-sector digitalization efforts.

It’s not realistic to predict a specific year when fax will vanish entirely. Legacy systems tend to fade gradually, disappearing once the economic benefit of switching finally outweighs the cost of staying put. Fax in Japan will likely fade not because everyone suddenly agrees it’s obsolete, but because fewer and fewer business partners will still require it.

Japan’s Fax Problem Isn’t Really About Fax

So, back to the apparent contradiction: Japan is a technologically advanced country that still uses fax. Once you understand the ecosystem fax is embedded in, those two facts stop looking like much of a contradiction.

Replacing a piece of technology is easy. Replacing the ecosystem built around it is much harder.

Japan doesn’t continue using fax because better technology doesn’t exist. It continues because countless business relationships and routines were built around a system that remains cheap, familiar, and compatible with everyone else still using it.

The real question was never simply why Japan hasn’t killed off the fax machine. It’s how long an old technology can survive when getting rid of it requires many interconnected users to change together — and that isn’t really a Japan problem at all.
