Dynamic Planning

Thanks to the success of Harenchi Gakuen, Dynamic Productions (ダイナミックプロダクション, also known as Dynamic Production or Dynamic Pro, ダイナミックプロ), was founded by Go Nagai with his brothers in April 1969.

Meant to be a group to help him with his works, as a consequence Harenchi Gakuen, where he derived almost no royalties from the TV series, films, or related merchandise, Dynamic Productions became a company established to manage Nagai's relations and contractual rights of his work. Dynamic became one of the first companies to require publishers sign contracts (even today many manga are created and published only on the basis of verbal agreements). It would start as a yūgen gaisha (limited company) and would change to a kabushiki gaisha (stock company) in 1970.

The same year of the foundation of Dynamic Pro, Ken Ishikawa joined the company. He would become Nagai's second assistant after Mitsuru Hiruta, who had been working with Nagai since the beginnings of Harenchi Gakuen. He would become one of Nagai's regular partners and his best friend. Ken Ishikawa participated as assistant in Harenchi Gakuen, Abashiri Ikka and Gakuen Taikutsu Otoko, particularly in the last one. In parallel with those activities as assistant, he co-produces with Go Nagai what would be in fact his professional debut in manga, Gakuen Bangaichi (1969-09-08 ~ 1970-09-22), and also his second manga, Sasurai Gakuto (1970-01 ~ 1970-05). He temporarily quit Dynamic Productions in 1970. This prompted Nagai to end Gakuen Taikutsu Otoko and the story of this series would be left inconclusive.

First success and controversies

Less than a year after debuting, he experienced his first big success. After being an unknown manga artist, he was invited to televised debates and journalistic investigations.

In 1968, while Shueisha was getting prepared to launch its first manga publication, Shōnen Jump, in order to compete with other magazines from rival companies (like Shōnen Magazine from Kodansha and Shōnen Sunday from Shogakukan), Nagai was invited to be one of the first manga artists publishing in the new magazine. He contemplated this, since he had to design a long-running series instead of the auto-conclusive short stories that he had been developing until that point. He accepted and the series became a big success, being the first for Nagai and making Shōnen Jump sell more than one million copies. With Harenchi Gakuen, Nagai was the first to introduce eroticism in modern manga and became the creator of modern erotic manga, opened the door to a new era in manga and also became the symbol of an entire generation. This work has influenced Japanese society radically, completely changing the common perceptions of manga.

Until Harenchi Gakuen, Japanese manga had been relatively tame affairs, but things soon changed. The manga became so popular that several live-action films and TV series based on the manga were developed. Harenchi Gakuen is considered as probably the work that has had the most influence in the world of manga at the end of the 1960s, leading the newly born Shōnen Jump magazine to sell millions of copies per week.

A scandalous manga in its time, it is a very innocent series by today's standards. At the time of its original publication, however, it met with severe criticism by some parts of the Japanese society. Harenchi Gakuen was criticized as vulgar because it introduced overt eroticism to children. Male students and teachers were depicted as being preoccupied with catching glimpses of girls' panties or naked bodies. Many parents, women's associations, and PTAs protested.

In particular, the PTA protests over Harenchi Gakuen were notorious. Nagai was bombarded with interview requests from newspapers, magazines and TV. Whenever he flew outside of Tokyo, TV cameras were waiting for him. He was branded a "nuisance" and even an "enemy of society". He, however, had a clear sense of what things he could or could not do with the manga.

At first, Nagai did not think that the opposition was against him, since he was aware of the standards that applied with movies and similar things for an audience below 18 years old. At that time, he never drew sex scenes, avoided pictures of genitals and made nudes cute rather than sexy, though the manga regularly showed male genitals throughout its run, including a castration scene. His fans supported him throughout the PTA protests. They sent him letters where they expressed how they were aware that the adults cracking down on them were reading raunchier stuff than what Nagai was producing.
