Okay kiddo, do you like watching TV shows? Just like how you have your favorite shows to watch, there are people in Japan who also love watching TV dramas. These dramas are like stories, but instead of being books, they are shown on TV.
In Japan, these TV dramas are called "doramas." Japanese TV dramas are quite different from your regular shows because they usually run for a short period of time, typically over the course of one season (usually around 10-12 weeks).
Each episode of the show is usually about 45 minutes to an hour long, and they tell a story that often has a beginning, middle, and an end. They have different types of genres, just like regular books or movies, so people can enjoy watching dramas that tell stories about romance, action, horror, or comedy.
One of the reasons that Japanese TV dramas are so popular is that they often reflect different aspects of Japanese culture. For example, tradition, food, and special customs may be heavily featured in the storyline.
And while Japanese TV dramas were originally only produced for a Japanese audience, they have now become popular around the world. Many people outside of Japan now watch these TV dramas, and they have even become popular in countries like China, Korea, and Taiwan.
So, that's a brief explanation of Japanese TV dramas. In short, they are like stories that are shown on TV, they usually run for a short period of time, and they reflect different aspects of Japanese culture.
