Japan's 2030 Digital Textbook Mandate — Three Forces Behind the Cabinet Decision

On April 7, 2026, the Japanese government approved the "Partial Amendment to the School Education Act" by cabinet decision. The bill positions digital textbooks as formal textbooks on par with paper versions, making them subject to government screening, adoption, and free distribution. With enforcement targeted for April 2027, digital textbooks are expected to enter classrooms from FY2030[1] following the screening and adoption process.

Each education board will choose from three formats: paper textbooks, digital textbooks, or a paper-digital "hybrid." Minister of Education Matsumoto stated that there would be "no uniform adoption" and that the goal was to "leverage the strengths of both paper and digital."

On its face, this decision appears measured. It preserves choice and retains paper textbooks. However, another fact overlaps with this cabinet decision.

On the very same April 7, the "Partial Amendment to the Personal Information Protection Act" was also approved by cabinet. This amendment includes provisions that, under certain conditions, waive the requirement for individual consent when using data for purposes including AI development classified as statistical production.

On Threads, a sharp observation was posted about this simultaneous decision: "They secured the tool for collecting education data and the right to freely use that data at the same time." The structural implications of this configuration deserve deeper examination.

Evidence from Pioneer Countries

While Japan moves toward formalizing digital textbooks, the rest of the world is accelerating in the opposite direction.

Sweden fully embraced digital education in 2009, deploying tablets en masse. However, in the PIRLS 2021 assessment, fourth-grade reading scores dropped from 555 to 544 points — an 11-point decline[2]. In August 2023, Education Minister Lotta Edholm revoked the mandate for digital devices in preschools, declaring that "Swedish students need more textbooks." That same year the government announced an investment of 64.7 million dollars[3] in book purchases for the country's schools, with a further 500 million kronor[3] a year in 2024 and 2025.

Two qualifications are needed. First, no conclusive study currently attributes Sweden's decline in reading ability to digitalization alone; shifts in the immigrant population, changes in reading habits, and teacher policy are all confounded with it. Second, Sweden made tablets mandatory across the board, whereas the Japanese scheme is an optional one under which each board of education chooses paper, digital, or a hybrid. That difference in context has to be taken into account whenever findings from pioneer countries are applied directly.

Norway has accumulated similar findings. In a study of more than 1,000 fifth graders, roughly one-third of students demonstrated significantly better reading comprehension on paper than on screen[4]. Eye-tracking analysis of over 25,000 fixations confirmed that screen reading tends to produce "shallower processing." PISA data also shows that the proportion of low-performing students rose from 19% (2018) to 27% (2022)[5], and Norway's Screen Use Committee issued a preliminary conclusion that "students should read more on paper."

One claim circulating on Threads — that banning smartphones in Swedish high schools "raised grades by 8% and reduced bullying by 30%" — requires qualification. While multiple studies exist on smartphone bans, Beland & Murphy's large-scale Swedish study found no clear improvement in academic performance. Bullying reduction estimates of 15–18% exist for the 12–14 age group. The specific figures cited likely derive from a limited study and should not be generalized.

Country	Indicator	Data	Response
Sweden	PIRLS Reading	555→544 (−11pt, 2016→2021)	€104M to bring back paper
Sweden	Policy Shift	2023: Revoked digital mandate for preschools	Paper as backbone, digital as supplement
Norway	Low Performers	19%→27% (2018→2022, PISA)	'Students should read more on paper'
Norway	Eye-Tracking	Screen reading → shallower processing	25,000+ fixations analyzed
Japan	Vision < 1.0	30% elem. / 60% middle / 70% high	20-20-6 rule recommendation only
Japan	Wi-Fi Bandwidth	Only ~20% meet required bandwidth	95% coverage vs. bandwidth gap

The Reality on the Ground: GIGA School

Japan's education ICT infrastructure has advanced rapidly in numerical terms. The GIGA School Initiative achieved one device per student, and classroom Wi-Fi coverage reached 95.7%[6].

But the voices on Threads target what lies beyond those numbers. "It bugs out when the Wi-Fi is bad. 'Digital! Great idea!' — that's what people who don't use it decided." This observation precisely captures the gap between coverage statistics and classroom reality. A December 2023 survey estimated that only about 20% of schools meet the required network bandwidth[7]. Wi-Fi access points may be installed, but when 40 students simultaneously open digital textbooks, the bandwidth chokes.

The plea "Stop making downloading and distributing digital textbooks part of teachers' jobs" reflects a structural shortage of ICT support staff. Digitizing textbooks effectively adds system administrator duties to the teacher's role.

Vision and Physical Impact

According to the MEXT School Health Statistics Survey, the proportion of students with uncorrected visual acuity below 1.0 has reached over 30% in elementary school, approximately 60% in middle school, and nearly 70% in high school[8]. This figure has consistently trended upward since the survey began in 1979.

In MEXT's FY2021 pilot study, the share of pupils reporting fatigue or pain after lessons using digital textbooks or devices was roughly 20 to 30 percent[9] among lower elementary pupils and roughly 20 to 40 percent[9] among upper elementary pupils and middle school students. The report notes that complaints centred on the eyes in the lower grades, and on the eyes plus neck and shoulders from the upper grades onward. Threads voices expressing worry about "children's screen time getting too long" and a parent noting that her daughter with borderline ADHD would "have even more trouble absorbing content" represent rational parental concerns about health risks.

Three Forces

This cabinet decision is not a simple "paper vs. digital" question. Three structural forces are operating behind it.

① Techno-Ideology

• 'Digital = Progress' assumption
• Policy inertia from GIGA School
• Pressure to 'utilize' 1:1 devices

② Industrial Policy Dynamics

• EdTech market: ¥3B → ¥80B (26×)
• Education ICT market → ¥364.4B growth
• Industry lobbying for adoption

③ Data Infrastructure

• Education data utilization roadmap
• Privacy law reform (same-day cabinet decision)
• Consent waiver for AI development

April 7, 2026 Cabinet Decision → FY2030 Deployment in Schools

Ideology, industry, data

The first force: Techno-ideology. With devices deployed nationwide through the GIGA School Initiative, a policy inertia drives the logic that "it would be wasteful not to use them." A ¥266.1 billion device renewal budget has been allocated, with approximately 10.6 million device replacements expected between FY2024 and FY2026. As long as the devices exist, structural pressure emerges to formalize the "textbooks" that run on them. The Threads post calling digital textbooks "a greater folly than yutori education" is extreme, but it can be read as an intuitive rejection of faith in progress unsupported by evidence.

The second force: Industrial policy. The EdTech market is projected to grow from ¥3 billion in FY2019 to ¥80 billion (a 26-fold increase) by FY2025[10], with the broader education ICT market expected to reach ¥364.4 billion. The Threads voice suspecting this is "all about vested interests — pushed through by the business world" is detecting this industrial structure.

At the same time, digitization threatens existing industries. The approximately 130 million textbooks printed annually form the baseline demand for regional printing and delivery networks. The Threads observation about "massive damage to publishing, printing, and paper industries" points to the asymmetry of industrial transitions — where winners and losers are different actors.

The third force: Data infrastructure. Digital textbooks generate vast behavioral data in the form of learning logs — which page was viewed for how many seconds, where students stumbled, in what sequence they read. This data is anticipated as the foundation for "individually optimized learning," but it simultaneously constitutes detailed cognitive and behavioral profiles of individual children.

That the privacy law amendment received cabinet approval on the same day provides important context for examining how the two policies fit together. No public evidence of deliberate coordination has been confirmed at this point, and the possibility that two independent policy processes simply converged cannot be ruled out. The amendment's provision waiving consent requirements for "AI development including statistical production" connects directly to potential education data utilization. MEXT has developed a roadmap for education data utilization with "realizing individually optimized learning" as its primary objective. Yet parents have received virtually no explanation of the conditions under which their children's learning data might be used for AI development.

The Demonstrated Benefits of Going Digital

Any account of the structural problems has to weigh the demonstrated benefits of digital textbooks just as fairly.

First, accessibility. For children with dyslexia or visual impairment, adjustable text size, read-aloud audio, and automatic furigana lower the barrier to learning, as multiple studies have shown. Digital delivers at low cost the kind of support that paper textbooks are structurally unable to provide.

Second, immediate updates. Paper textbooks carry a lag of several years between adoption and classroom use, which makes correcting errors or reflecting new data difficult. Digital allows updates within a defined scope even after certification.

Third, the possibility of individual optimization. For adaptive learning built on learning logs, some studies confirm gains for students with lower mastery, depending on how the model is designed. Realizing that possibility, however, presupposes the governance framework described under the third force.

Even granting these benefits, the question worth asking is not "digital or paper" but "under what conditions is digital effective." The "optional use" direction set by the current cabinet decision is sound; the core problem is that the infrastructure and the rules needed to make that choice real have not caught up.

Beyond the "Paper or Digital" Question

Structurally classifying the 12 Threads posts reveals that citizen concerns fall into five layers:

1. Health risks (vision, concentration, developmental impact) — a domain where scientific evidence is accumulating
2. Cost externalization (Wi-Fi bandwidth, teacher burden, device failure) — a gap between decision-makers and burden-bearers
3. Selective reference to precedents (insufficient consideration of Swedish and Norwegian evidence)
4. Asymmetry of industrial transition (EdTech beneficiaries vs. printing, publishing, and logistics casualties)
5. Data governance vacuum (underdeveloped rules for collecting and using education data)

The common thread across these concerns is the gap between "those who decide" and "those who are affected." The Threads post stating that "tablets are banned from Diet plenary sessions, yet children's textbooks go on tablets" is factually imprecise — committees have actually permitted tablets and laptops. However, the structural intuition the post captures — that policymakers do not bear the inconveniences of digital while imposing it on children — is worth analyzing.

Japan is still ahead of the result

Sweden reversed course to paper textbooks only after the "results" — declining reading scores — materialized. Japan currently stands at the stage before those results emerge. The question is whether Japan can reference pioneer evidence and build governance mechanisms at the design stage.

Specifically, three minimum conditions are necessary for the "choice system" to function in both name and substance: (1) an independent evaluation committee for ongoing monitoring of academic and health impacts, (2) a clear consent framework governing the scope of education data utilization and third-party provision, and (3) substantive guarantees of education boards' right to choose paper without implicit pressure toward digital adoption.

Noriko Arai's 『ほんとうにいいの?デジタル教科書』 (Is It Really OK? Digital Textbooks)（外部サイト、新しいタブで開きます） (Iwanami Booklet) critically examines the evidence underlying the push for digital textbook adoption.
