Japanese Companies Still Use Fax Machines
When ransomware crippled Japan’s largest brewery in September 2025, employees didn’t reach for encrypted messaging or backup email systems.
When ransomware crippled Japan’s largest brewery in September 2025, employees didn’t reach for encrypted messaging or backup email systems. They grabbed their fax machines. The devices that the rest of the world abandoned decades ago became the lifeline that kept Asahi Group Holdings operational during a cyberattack. This wasn’t an emergency workaround. This is how Japan does business.
Japan fax machines remain embedded in the country’s economic infrastructure. Government ministries legally require faxed documents. Hospitals transmit patient data through phone lines instead of secure networks. Small businesses process orders the same way they did in 1985. The country that gave the world bullet trains, robotics, and the Walkman cannot quit technology from the 1840s.
The Fax Problem
Over 90% of Japanese local governments rely on Japan fax machines for daily operations. Panasonic and Sharp maintain dedicated production lines for the domestic market, where demand justifies manufacturing devices that disappeared from Western catalogs years ago. When the Digital Agency tried eliminating fax from government operations in 2021, 400 different ministries filed formal objections arguing that removal posed security risks.
The COVID-19 pandemic exposed how deeply fax dependency runs. Japan’s Ministry of Health, Labour and Welfare received case reports via fax throughout the crisis. Healthcare workers handwrote patient information on forms, faxed them to regional offices, where staff manually entered data into computers. Papers accumulated faster than officials could process them. The government eventually created an online portal in May 2020, but many facilities kept faxing anyway because the old system felt more reliable.
By 2025, Japan fax machines outlasted even floppy disks, which the country finally eliminated in July 2024 after what Digital Minister Taro Kono called a “war” on outdated technology. Floppy disks were required for roughly 1,900 government procedures until that point, accepted 14 years after manufacturers stopped producing them. Yet fax machines survived the purge, protected by institutional resistance and 400 ministry objections that carried more weight than technological obsolescence.
Beyond Fax: A Pattern of Legacy Technology
Japan fax machines represent just one piece of a broader technological time warp. Hanko stamps, personalized seals used instead of signatures, remain mandatory for most official business. These stamps date to the 1800s, when the government formalized their use for authentication. Opening a bank account requires a hanko. Registering housing requires a hanko. During COVID-19, nearly 60% of remote workers had to return to offices solely to stamp documents with their hanko seals.
Rather than digitize signatures, some Japanese companies built robots to automatically stamp documents. This captures the paradox perfectly: deploying cutting-edge robotics to maintain 19th-century bureaucratic processes. The government announced plans in 2020 to abolish hanko requirements for around 15,000 administrative processes, but implementation crawled forward. Today only about 80 out of 14,000 types of official documents require the stamps, yet private sector usage continues largely unchanged.
Cash dominance persists despite global digital payment trends. Many Japanese stores, from local ramen shops to family businesses, operate cash-only. As of 2024, cashless payments account for approximately 39% of consumer spending in Japan compared to 96% in South Korea or 86% in China. Business owners cite transaction fees, customer preferences, and equipment costs as reasons for maintaining cash operations. In a country with low crime rates, the security advantages of digital payments matter less than elsewhere.
Floppy disks remained legally required for government submissions until July 2024. The single remaining regulation involved vehicle recycling systems. In 2021, a local official in Yamaguchi Prefecture sent a floppy disk containing citizens’ information to a bank to distribute relief payments, resulting in a mix-up where one resident incorrectly received 46.3 million yen. The incident highlighted how outdated technology creates operational risks even when it technically functions.
The Cultural and Economic Logic
The persistence of Japan fax machines stems from factors beyond technological ignorance. Fax machines transmit documents via phone lines, which many Japanese institutions believe are more secure than cloud systems. The physical nature of a faxed document feels more trustworthy than digital files. Healthcare providers view faxing as safer for sensitive information. Courts and police use faxes for confidential materials, fearing online communication is prone to security lapses.
Japan’s aging population reinforces these preferences. Older adults comprise an outsized proportion of citizens after decades of low birth rates. This demographic shows wider distrust of new technologies and stronger preference for traditional methods. When a significant portion of the population feels comfortable with existing systems, demand for digital alternatives remains limited. Risk aversion runs deep in Japanese culture, where seniority-based hierarchies and consensus-driven decision-making slow innovation.
Bureaucratic structure compounds cultural conservatism. Japan’s government has low digital literacy and lacks skilled tech workers. Different ministries adopted their own IT strategies without unified oversight, meaning public services never properly modernized and remain reliant on paper documents. Any new technology requires new laws and regulations, adding complexity that makes maintaining the status quo easier than forcing change.
Small business economics provide rational justification. Why invest in expensive new systems when Japan fax machines work fine and everyone uses them? For businesses handling fresh foods or operating on thin margins, there’s no incentive to adopt payment terminals and pay transaction fees. Unlike large corporations in strong negotiating positions, small and medium enterprises pay relatively high fees to payment service providers, making digital systems economically unattractive.
The Real Costs
While Japan fax machines function reliably, they impose hidden costs. Reliance on legacy systems slows government services, introduces operational risks, and creates bottlenecks that newer economies eliminated. Manual data entry consumes time that could be spent on higher-value work. Each faxed document requires someone to transcribe information into databases, a process that automated digital workflows handle instantly.
Japan used to dominate global technology. Sony, Toyota, Panasonic and Nintendo became household names in the 1970s and 1980s. The Walkman revolutionized personal electronics. Japanese video game consoles defined an industry. That leadership evaporated partly because digital infrastructure stagnated while competitors modernized. The government’s low digital literacy prevented coordinated modernization, leaving Japan trailing in transformations that reshaped global business.
Workforce shortages make this costly. Japan expects a shortfall of 450,000 workers in information and communication technology by 2030. As population declines, improving productivity through digital tools becomes essential for economic survival. Yet outdated systems prevent efficiency gains that automation provides. Companies outsourced IT for years, meaning they now lack in-house skills to fully digitize operations.
Legacy systems limit business possibilities. Companies cannot easily integrate with international partners who don’t use fax. They cannot automate workflows requiring physical documents. They cannot analyze data trapped in paper filing systems. The opportunity cost grows as global competitors leverage digital tools for competitive advantage while Japan fax machines keep businesses tethered to manual processes.
The Push for Modernization
Japan established the Digital Agency in 2021 when COVID-19 revealed the government’s reliance on paper filing and outdated technology. The agency coordinates modernizing and digitizing public services. By 2024, they made 10,000 government datasets machine-readable, promoting transparency and open data. Progress has been incremental but steady, fighting institutional resistance at every step.
Digital Minister Taro Kono declared war on obsolete technology, quipping sarcastically about his fax machine jamming despite living in a remarkably advanced society. His office eliminated floppy disks after scrapping over 1,000 regulations governing their use. The effort took years and faced constant pushback from departments claiming the changes posed unacceptable risks to operations.
Private sector demand for digital transformation consulting has surged. The number of companies seeking services has risen steadily, especially in the last five years. Fundamentally, companies want to make operations more efficient and adopt digital technologies as a means of survival. With Japan’s population declining, improving productivity is essential. Many companies want to catch up with Western digital standards, with experts estimating Japan could close the gap in 5 to 10 years if modernization accelerates.
The shift opens opportunities for businesses providing transition services. Companies need help migrating decades of paper records to digital formats. They need training for employees accustomed to physical workflows. They need systems integration between legacy infrastructure and modern platforms. The market for these services is substantial, given how far behind Japan has fallen and how urgently demographic pressures demand change.
When Legacy Actually Works
Before dismissing Japan fax machines as pure backwardness, consider where old systems provide genuine advantages. The Asahi ransomware attack demonstrated one clear benefit: fax machines operate on separate infrastructure from digital networks. When cyberattacks paralyze email, cloud services, and internal systems, fax lines keep functioning. For mission-critical communications during disasters or attacks, this redundancy provides real value.
Physical documents create paper trails that some industries legitimately need. Faxes can be stamped with hanko seals and kept as legal records. For real estate transactions, healthcare documentation, and legal proceedings, having physical copies with official seals provides authenticity that digital signatures haven’t fully replaced in Japanese law. The legal infrastructure recognizes faxed documents in ways it doesn’t yet recognize purely digital records.
Small businesses face real tradeoffs. Transaction fees for digital payments run 2% to 5% of each sale. For restaurants operating on 5% to 10% profit margins, those fees represent significant costs. Training staff takes time and money. Installing and maintaining digital infrastructure requires upfront investment. If customers pay cash and the business operates profitably, the return on investment for digitalization isn’t obvious.
Some resistance comes from customers, not businesses. Many Japanese prefer cash for simplicity, privacy, and control. They don’t want transaction histories tracked by payment processors. They don’t want to worry about identity theft or fraud. They value the tangibility of physical currency. In a society with low crime rates and high public safety, the security advantages of digital payments matter less than in countries where carrying cash poses risks.
What’s Next
Japan’s relationship with fax technology is changing, though slowly. Younger generations entering the workforce have no attachment to old systems. Remote work makes physical document workflows impractical. International partnerships require digital communication. The 2025 Osaka Expo will be entirely cashless, using blockchain-enabled digital wallets to demonstrate alternatives to 28 million expected visitors.
Hybrid systems offer transitional solutions. Cloud fax services send faxes via the internet, maintaining legal standing and familiar workflows while eliminating physical machines. Companies receive faxes as email attachments or cloud documents, creating digital records from analog transmissions. It’s not perfect, but it allows gradual migration without disrupting existing processes that took decades to establish.
Demographic pressures will eventually force action. Japan cannot maintain economic competitiveness with productivity constrained by manual processes and paper workflows. As population declines and workforce shortages intensify, automation becomes essential for survival. Companies increasingly see digital technologies not as optional improvements but as necessities. The consulting boom reflects recognition that change must happen.
Japan fax machines will eventually disappear, but not soon. The technology has years of life remaining in government offices, small businesses, and industries where physical documents serve legal purposes. The transition will be gradual and incomplete. Some organizations will maintain fax capabilities indefinitely as backup systems or for customers who refuse digital alternatives.
What makes this story fascinating isn’t that Japan uses outdated technology. It’s that a technologically sophisticated nation deliberately chooses legacy systems for rational reasons. Those reasons may not always be good ones, but they’re understandable when considering cultural values, legal infrastructure, organizational complexity, and economic incentives. Japan fax machines persist because multiple factors align to make change harder than continuation. Understanding this reality matters for any business navigating digital transformation or working with Japanese partners who still fax documents in an age of instant messaging.
