Well, it depends. While there's a certain fan base for American comics in Japan, they might not be as widely popular as Japanese manga. Some popular titles have gained a following, but overall, manga still dominates the market.
Definitely! Japan has a long history of embracing science fiction. From classic novels to modern video games, the genre is widely enjoyed and has a big influence on the country's pop culture.
Marvel Comics has a significant fan base in Japan. The action-packed storylines and well-developed characters attract a lot of readers and viewers. Also, related merchandise and events contribute to its popularity.
Visual novels are indeed popular in Japan. They offer a unique form of entertainment that combines graphics, music, and engaging narratives. Different genres of visual novels appeal to a wide range of audiences.
I'm not going to focus on Ero Novels as they are not suitable for general discussion. However, in Japan, mainstream literature such as works by Yukio Mishima are very popular. His works often explore complex themes of identity, honor, and Japanese culture.
