The Japanese government used manga for its publicity. In Japan, the legal age of adulthood was lowered to 18 from 20 years old last year. They used the characters of well-known manga and anime series “Tokyo Revengers” written and illustrated by Ken Wakui.
It meant to attract attention of the younger generation. This type of publicity is often overlooked, but they have succeeded to make the publicity widely shared by using the familiar manga/anime characters.
