This “My Tezuka Osamu 1” is an extremely valuable text that records, from an insider’s perspective, the rarely told 1960s scene at Mushi Production.

This is a Comiket item, so there isn’t a fixed retail price.
On BOOTH the price is 2,500 yen.
If you come to Equal Books (イコール書店), it will be sold for 1,500 yen.

The author is Mamoru Masaki, who—before debuting as a manga artist—served as production coordinator on TV anime such as Astro Boy and Jungle Emperor, and was in the thick of Mushi Pro’s production hell.

In 1963 (Showa 38), at 22 years old, a young man from the countryside was thrown straight into the forefront of Japanese anime history.

Tezuka Osamu’s obsession, drawing until blisters formed on the paper (not pen blisters).
Endless all-nighters.
A schedule on the verge of collapse.
Chaos in each department, broken outsourcing, and the psychological pressure concentrated on the production staff.

Even so, to finish a work the site had to overcome everything.

The precariousness of having a “genius” at the center.
Friction within an organization that was losing control as it grew. The raw energy and unrefined passion of young talents.
The handmade rush that characterized the early days of anime rises not as a record but as an experience.

This is not a polished story; it is unvarnished reality.
It realistically depicts the workplace’s contradictions, exhaustion, shouts, and anxieties.

There is another reason this book suits Comiket.

Masaki used the pen name Toge Akane in COM magazine and founded a nationwide organization for aspiring manga artists called Gura-Kon, where he:
- actively introduced doujinshi and ran feature articles
- built networks crossing readers and creators
- provided pathways for amateur artists to debut in commercial magazines

In other words, he actually stood at the source of the doujin culture that later led to Comic Market.

Commercial and doujin.
Professional and amateur.
Production sites and reader communities.

This is the record of someone who lived at those boundaries in an era when no one had yet named them.

For those interested in anime history.
For those who want to know Tezuka Osamu not as a myth but as a real person.
And for those who like the reality of creative workplaces.

This is not a retrospective commentary compiled after the fact. It is writing that retains the warmth of a person who was in the midst of it.
