I think it's also safe to say genre TV and movies were a big influence - the first stories I ever tried to write were Godzilla fan fiction when I was in elementary school, complete with elaborate maps of Monster Island made with multiple sheets of typing paper and nearly six feet wide. I kind of wish I still had those.
Really interesting genre films, especially monster movies, evoke the fears of the times intentionally. Our starting point was 'Godzilla' - the original movie was released less than 10 years after Hiroshima, and it's a classic in Japan.
I don't know what it is about 'Godzilla,' but as far as I'm concerned, the more versions of it, the better.
I find Godzilla exciting because he/she/it comes from the sea. It's entirely plausible that it could be real. Yes it is! It doesn't take a huge stretch in the imagination to imagine that something may be living at the deepest depths of one of our oceans.
What's beautiful about Godzilla is, of course, it's in every way a symbol of Japan dealing with the aftermath of the atomic bombs being dropped on them, and their ideas of how they're affected by it.
The bigger your platform gets - it kind of feels like being Godzilla sometimes. You make a slight move and you can accidentally knock over a building. It's a tough thing to navigate.
