Of course. Japanese light novels are written in Japanese and thus are composed mainly of Japanese words. They might incorporate a few foreign words or modern slang, but the core language is Japanese.
Well, there are several places. Some people recommend subscription-based services like BookLive or Kindle Unlimited Japan. Also, some manga authors have their own official websites where you might find their works in Japanese. Just make sure to have a reliable internet connection and a way to make payments if needed.
Another great Japanese novel could be 'The Tale of Genji'. It is often considered the world's first novel. It gives a detailed look into the Heian period in Japan, with its courtly life, relationships, and the social norms of that time. It's a long and detailed work that has influenced many aspects of Japanese culture.
Japanese creation stories reflect Japanese culture in several ways. For example, the emphasis on harmony and order in the stories, like how the gods worked together to create the world, reflects the Japanese value of group harmony. The respect for nature seen in the creation stories, such as the islands being formed from the ocean, shows the deep - seated connection the Japanese have with nature.
Classic Japanese novels have had a profound impact on Japanese culture. For instance, 'The Tale of Genji' established many of the norms and ideals related to courtly love and social hierarchy in the Heian period. It influenced not only literature but also art, as paintings and other forms of visual art were often inspired by its characters and scenes. 'Natsume Soseki's works, like 'Kokoro', reflected the modernization of Japan and the resulting tensions. His exploration of the individual's struggle within a changing society became a part of the Japanese cultural consciousness.
I'm not aware of many specific Japanese light novels directly centered around the Korean - Japanese war. But considering the rich history between the two countries, it wouldn't be surprising if there are some out there. It could be that some indie or less - known authors have explored this theme, maybe in a coming - of - age story where the main character discovers family secrets related to the war.
