Why do Japanese anime almost always involve summer festivals? I have seen many movies, and almost all of them have this plot.

What you should watch is an idol drama with the theme of youth emotion. First of all. Summer festivals are traditional festivals in Japan. Anyway, this is a celebration worthy of thanks and wishes. . . Then, in summer festivals, Japanese women have to wear bathrobes, and men can wear them or not. This in itself contains the inheritance and persistence of Japanese traditions, and it also vaguely exudes a series of activities such as setting off fireworks and dancing around the fire, so it is particularly easy to happen. To sum up, it is especially suitable for the brewing and development of feelings. Therefore, Japanese anime often has a plot of a summer festival. . .
