Gekiga is a style of Japanese manga that emerged in the late 1950s, characterized by its more serious and adult themes compared to traditional manga. It often explores complex subjects such as social issues, personal struggles, and psychological depth, appealing to a mature audience. The term "gekiga" translates to "dramatic pictures," and it was popularized by artists like Yoshihiro Tatsumi and Katsuhiro Otomo. This genre paved the way for a broader acceptance of manga as a legitimate art form, influencing both Japanese and international comics.
