The mid-1990s were the commercial peak of print manga, with magazine circulation reaching levels never matched since. The decline that followed was a print decline rather than an industry one, and it pushed manga toward digital distribution and international markets. The question reduces to 4 — the structure.

Manga magazine circulation reached its high point in the mid-1990s. The largest weeklies achieved figures in the millions per issue — numbers no comics market anywhere has approached before or since, and which are difficult to convey to readers who only know the current landscape.
This was a genuinely mass medium in the way broadcast television was: a substantial fraction of a country reading the same chapters in the same week.
A cluster of extraordinarily popular series ran simultaneously, several of which became internationally recognised. Anime adaptations amplified their reach and fed readers back to the magazines. Home video and merchandising built revenue streams beyond print.
Crucially, the audience that grew up with manga in the 1970s and 1980s had not stopped reading, so the market was serving children and adults at once rather than replacing one with the other.
Circulation has fallen substantially and continuously since. The causes are mostly not specific to manga: print media declined broadly, competing entertainment multiplied, and Japan's demographics shifted with a shrinking younger population.
It is important to be precise about what fell. Magazine circulation collapsed. Total manga readership and revenue did not follow it down nearly as steeply, because reading moved rather than stopped.
These shifts show up in the work. Web-first serialisation removed some of the survey pressure that shaped magazine manga, allowing series with slower openings or narrower appeal to survive. Digital publication made colour and variable chapter lengths practical. Competition from Korean vertical-scroll webtoons has pushed some publishers toward that format.
The result is a more fragmented medium than the 1990s one. There is no longer a single magazine whose rankings function as a proxy for national taste, which is a loss of coherence and a gain in range.
The arithmetic is unremarkable and worth doing anyway: 112 across 7 words, reducing to 4. The weight sits in “Aftermath”, which carries 38 on its own and reduces to 11.
What the 4 brings is foundation. The reference files it as a structure. Whatever else this explainer is doing, it is doing it with the 4's insistence that what lasts must be built patiently.
Heart's Desire 9, Personality 4: reckoning underneath, foundation on the surface. The gap between them is where the subject is most interesting.
The 4 asks you to look for the constraint the subject was working inside. The 4 confuses the frame for the work. Structures outlive their usefulness, and several entries here describe conventions kept long past their reason. The other explainers that reduce to 4 are collected on The Structure.
