It's mainly because of the traditional reading direction in Japanese culture. In Japan, they read from right to left, which is why manga follow that pattern.
To read Japanese manga effectively, it's good to have a basic understanding of Japanese grammar and culture. Familiarize yourself with common manga genres and their tropes. And don't rush, take your time to enjoy the art and story.
You can try some manga forums or communities. Sometimes, users share links to free manga reading sites. But be careful, as some of these might not be legal or reliable.
For a great manga reading session, start with choosing a manga that interests you. Sit back, relax, and let your imagination run wild as you follow the panels. Also, don't be afraid to go back and re-read sections if you miss something important.
To read manga books well, start at the top right of each page and move left. Focus on the art style and how it conveys emotions. And don't rush; take your time to soak in the story elements.
Manga can definitely be classified as books. They offer entertainment, imagination, and knowledge, similar to regular books. But they often have a more graphic and dynamic presentation.
