The circumstances behind the publication of Sakaguchi Ango's controversial piece, "Theory of Degeneration," have been revealed. Sakaguchi's exploration of the moral decay in post-war Japan garnered mixed reviews upon its debut and continues to spark debate. Critics and fans alike have long speculated the reasons behind its original publication, and this mystery has finally been solved.

In Japan, Sakaguchi Ango’s work has been historically divisive, with some revering his brutal honesty about societal issues, while others consider his viewpoints too bleak. "Theory of Degeneration" particularly discusses society's moral decline after World War II, which was a deeply sensitive topic. The publication details of such a significant piece would interest many in the literary and academic circles, offering insight into the intellectual climate of its time.

In the US and EU, much like in Japan, authors like Sakaguchi Ango often spark debates and discussions. The publication details or motivations of controversial pieces of literature may also come under scrutiny. However, the interest might not be as intense due to cultural differences and varying degrees of investment in the literary scene.
