4-Koma is a style of Japanese comic strip that consists of four panels arranged vertically. Each panel typically follows a specific structure, often leading to a punchline or humorous conclusion in the final panel. This format is popular in manga and is used to convey jokes, short stories, or character interactions in a concise manner. The simplicity and brevity of 4-Koma make it accessible to a wide audience, allowing for quick reading and easy enjoyment. Many manga series, such as Yotsuba&! and Azumanga Daioh, utilize this format to deliver entertaining content in a compact form.
