Introduction: The Gap Between Self-Image and Reality

“Japan is a manga superpower.” We say it almost without thinking. Japanese manga is celebrated worldwide, and IP businesses built around manga and anime are even discussed as a pillar of national growth strategy.

Yet that very self-image may be concealing a quiet erosion beneath the surface.

Publishing journalist Kazufumi Iida warns that “a silent disengagement from manga among children and young people is steadily progressing.” The reason the market looks healthy at first glance is that adult spending on digital comics is propping up the numbers. Meanwhile, the next generation of readers is drifting away.

The ¥700 Billion Market — and Its Hidden Reality

In the 2020s, Japan’s manga market — combining print volumes, manga magazines, and digital comics — has reached approximately ¥700 billion, a record high. On the surface, manga culture appears rock solid.

However, the engine driving this growth is primarily digital comics, and their main consumers are adults with disposable income. In other words, children and young people are not fueling the market’s expansion — they are, in fact, moving away from it.

Until 2004, manga magazines were actually larger than collected volumes in terms of market size. The reversal marked the end of an era when magazines served as the primary gateway drawing children into the world of manga.

Today’s “booming market” is sustained by adults who already grew up with manga and continue to consume it. When it comes to cultivating new readers, the situation may be far more precarious than the headline numbers suggest.

The Fall of Manga Magazines: Readership Down to One-Tenth

The School Library Survey conducted by the National School Library Council is one of the few sources of long-term data on children’s reading habits. According to this survey, the average number of magazines read per month has collapsed — from over 10 magazines a month for high school students at the peak, to just 1.0 per month in 2025.

Even more striking is the non-readership rate: 77.7% of high school students now read zero magazines in a given month. Nearly eight out of ten high schoolers never pick up a magazine at all.

Comparing the 1996 and 2019 editions of the School Library Survey, the decline in readership for specific titles is stark.

■ Most-Read Magazines by Grade: 1996 vs. 2019

CoroCoro Comic among 4th-grade boys is relatively resilient, but every other category shows severe decline. Most dramatically, Weekly Shonen Jump readership among 7th and 10th-grade boys has collapsed to roughly one-tenth of its 1996 levels.

This trend has continued beyond 2019, and current readership is thought to be even lower. The era when kids passed dog-eared copies of Jump between friends feels like a distant memory.

Volumes and Digital: The Decline Continues There Too

The drop isn’t limited to magazines. A joint survey by Benesse Educational Research Institute and the University of Tokyo found that print manga readership rates in 2023 stood at 68% for elementary students, 60% for middle schoolers, and 49% for high schoolers.

Compared to 1985, readership has fallen by more than 20 percentage points across all school levels.

One might assume that readers have simply migrated from print to smartphones. But digital readership data tells a similarly sobering story: Japan’s digital comics readership rates are 15% for elementary students, 35% for middle schoolers, and 49% for high schoolers.

This is not a smooth shift from print to digital. Those who stopped reading print largely haven’t picked up digital — they’ve simply stopped reading manga altogether.

Japan vs. Korea: A Shocking Gap in Digital Comics Readership

The contrast with South Korea’s webtoon industry is striking. According to South Korea’s National Reading Survey, webtoon readership rates stand at 45% for elementary students, 69% for middle schoolers, and 70% for high schoolers.

The gap becomes immediately apparent when the two countries are placed side by side.

■ Digital Comics Readership: Japan vs. South Korea (circa 2023)

Among middle and high schoolers, South Korea’s overall comics readership rate — print and digital combined — already surpasses Japan’s. Korean children are engaging with comics more than their Japanese counterparts across every format.

The root cause lies in a fundamental difference in business models.

How the “Adult Monetization Model” Shut Young Readers Out

Japan’s digital comics market grew by focusing on adult-oriented content with high conversion and spending rates. It was a rational business decision — but it came with serious side effects.

Content aimed at elementary and middle school students — who lack payment methods or have very limited budgets — was severely neglected. Most manga apps set their recommended age at 15 or 18 and above, effectively locking younger readers out of the digital ecosystem entirely.

A telling example: manga apps began their mainstream rise in 2013–2014. Yet a dedicated online weekly manga magazine for elementary schoolers — the digital version of CoroCoro Comic — didn’t launch until 2022. Nearly a decade passed with no proper digital gateway for young readers.

During the very years when children were forming their digital content habits, Japan’s manga industry failed to build an accessible on-ramp for them.

Why Korean Webtoons Succeeded: A “Three-Story” Business Model

So how did Korean webtoons manage to capture young readers so effectively? The story begins in the late 1990s with “essay toons” — personal diary-style webcomics that blurred the line between prose and illustration. These works found a passionate following among young readers online.

By the early 2000s, major Korean portals like NAVER and Daum — equivalents of Yahoo! Japan — had launched their own webtoon platforms. Since these portals made money through web advertising, their priority was simple: reach as many readers as possible, for free. Gag strips, comedy series, essay toons, and educational manga were all made freely available to attract a wide audience.

NAVER Webtoon still offers over 90% of its content for free today. Even teenagers with no spending money can access an enormous library of titles with nothing more than a smartphone.

The Korean webtoon business can broadly be described as a “three-story” structure:

■ The Korean Webtoon “Three-Story” Business Model

Japan’s digital comics market is critically weak at the “ground floor.” Without a broad base of freely accessible, youth-friendly content, young readers have little reason to engage in the first place.

As a result, Korea is growing a generation that falls in love with webtoons in childhood and gradually becomes a paying readership as they age. Japan, by contrast, has left that critical nurturing stage largely unaddressed.

Adults Are Drifting Away Too: Readership Data Across All Ages

The problem isn’t confined to younger generations. A 1985 Mainichi Newspaper public reading survey found overall manga readership at roughly 20%. Subsequent surveys showed that approximately 70–80% of those aged 16 and above did not read manga, a figure that held relatively stable until the survey ended in 2019.

Breaking it down by age group, a clear pattern emerges: readership declines steadily with age.

■ Manga Non-Readership Rate by Age Group

Across all generations aged 16 and over, only about 20–30% read manga. Even among teenagers, roughly half do not read manga at all. The notion that “Japanese people love manga” is, statistically speaking, already a relic of the past.

The current digital comics market is being kept afloat by adults in their 30s and 40s who grew up reading manga. But as this cohort ages, their consumption will naturally taper off. If a new generation of readers isn’t being cultivated to replace them, the market faces a sharp contraction.

A Negative Spiral Quietly Taking Hold

As fewer children grow up reading manga, fewer will aspire to become manga artists. With a shrinking pool of creators, the diversity and volume of titles will decline — which will drive away even more readers.

Even those who do pursue a career as manga artists will find it harder to make a living if the readership base is too small. Economic insecurity will push talented creators toward other fields, further depleting the creative ecosystem.

This negative spiral is advancing in ways that are easy to overlook. As long as market revenue figures continue to look healthy, the urgency is hard to feel. But that very complacency may be the greatest threat of all.

Conclusion: What Can Be Done to Protect Japan’s Manga Culture?

Japan’s pride in being a “manga superpower” was once grounded in reality. But the foundation of that identity is silently crumbling.

The core problem is that Japan’s digital comics market was built entirely around adults who can pay right now — with little investment in the “on-ramp” that would cultivate tomorrow’s readers.

As the Korean webtoon model demonstrates, giving children free, easy, and wide-ranging access to manga is what builds a lasting readership base over the long term.

Pursuing an IP-driven strategy to generate export revenue through manga is not wrong in itself. But without continuously nurturing “people who love manga,” that strategy risks becoming a castle built on sand.

Now is the time for the industry, government, and education sector to work together to rebuild the gateway connecting children and manga. The future of Japan’s manga culture ultimately depends on whether the next generation can discover, simply and joyfully, that manga is worth reading.
