Who is the author of kokology?

"Kokology" is a popular series of books that originated in Japan. The books themselves are not attributed to a single author, but rather a team of psychologists.

The books were originally written by a group of Japanese psychologists and then translated into English.

It's important to note that the books are not considered serious psychology and are more for entertainment and self-discovery. While the exercises can be fun, they lack scientific backing.
