Kishōtenketsu describes the structure and development of classic Chinese, Korean and Japanese narratives.

The structure originated in China and used in poetry as a four-line composition. From there, it moved to Korea and Japan

Sometimes described as a narrative structure devoid of conflict, particularly in opposition to Western narrative styles.

Parts
1. Start or introduction, usually meaning the reason a thing begins
2. Handling, process, or hardships
3. Turn, turning point, crescendo
4. Result.

This is in contrast to the traditional three act western structure.

1, Setup
2. Confrontation
3. Resolution.

As the following video explains, this is the structure of the Studio Ghibli and the director Hayao Miyazaki. It is what makes the films different and unique to westerners.
