Genetic tradition

The types of these three companies are not the same. Genese's office occupies a male-dominated world in Japan, and Johnny's office was established in 1962. After more than 40 years, idol DreamWorks has emerged in an endless stream, occupying half the sky in Japanese entertainment circles. Compared with Niu Yi, Aihui's female singers are all Aihui's, such as Ai Otsuka, Kumiko, Ayumi Hamasaki, Namie Amuro and Bao Er. The full commercial name of Giza Studio is ギザ, which belongs to existence.

If there are three, I think the ranking is Genese Office, Aihui and Giza Studio.
