Digging deeper into the kaiju crevices, we find a lot of minor monster flicks from the “monster factory of Nippon”, Toho, in this case being a mini-series made of 4 episodes and with a confusing release history, as it was completed in 1964, but wasn’t broadcasted on Fuji TV until 1968, after Toho realized the project involved two of their own talents, with Fuminori Ohashi (Tsuburaya’s special effects apprentice) and writer Shinichi Sekizawa, already proven for penning other kaiju classics such as Mothra, Mothra Vs Godzilla and Godzilla VS Mechagodzilla (the 1974 one), and the company was convinced that Agon didn’t directly step on the nuclear toes of their monster star.

I said a confusing release history because in mid 90s the episodes were recompiled into a feature lenght film and distributed internationally onn VHS as Agon: Atomic Dragon… and i can’t find any source that actually pinpoints when exactly it was released in the 90s, Letterboxd instead says it was in the 80s, and there’s also a japanese DVD release in 2005 by King Records.

Thankfully is not hard to find in any form, as the english subbed episodes can be found on Youtube, and you might stumble upon fansubbed releases of the feature lenght compilation version.
