Junior idols are young girls, around your age or a little older, who have talents like singing, dancing, modeling, or acting. They perform in front of a live audience or on videos that people can watch. They are usually famous in Japan, which is very far away from us.
But why are they called Junior idols? Well, "Junior" means "young" or "little", and "idols" are people who are admired by many fans. So, these little girls who are admired by many fans are called Junior idols.
Now, some people love to watch Junior idols because they think they are cute and talented. But some people think it is not right to have little girls perform like adults, and they worry that it can be unsafe or exploitative.
So, in conclusion, Junior idols are young girls who are admired for their talents, but some people think it is not right for them to perform in front of adults.
