Dispute with Kumi Koda

Yajima Beauty Studio’s third single <はまぐりボンバー> coincided with Japanese female singer Kumi Koda’s single <3 SPLASH> in 2009 It was released on the same day on July 8th, and the result was that Koda Kumi was defeated by Yajima Beauty Room with only 60,000 copies sold. When appearing on the famous Japanese program , Yajima Beauty Room member Xiao Strawberry touched Koda kindly. Kumi was rejected by Koda Kumi. From then on, Koda Kumi held a grudge against Yajima Beauty Parlor. At the a-nation'09 tour concert held by the company, Koda Kumi learned that Yajima Beauty Parlor made a grand appearance as a special guest. Backstage, Yajima's beauty salon gave Kumi Koda a "clam mirror" and "clam underwear" as tokens of friendship, but Kumi Koda thought the gifts were cheap and uninterested, so he left after only singing two songs. The cover of Kumi Koda's best album released in 2017 also showed him "wanting to eat a strawberry", which was a metaphor for killing strawberry, a member of Yajima Beauty Salon! The reason why Koda Kumi hates Yajima Beauty Salon is because of this. Everyone in the company AVEX is also well-known. Yajima Beauty Studio is not to be outdone. In their first album released in 2010, they specially used the circus pattern from Koda Kumi's hit album "TRICK" as an inner page.

Become friends with Ayumi Hamasaki

Sympathetic, Hamasaki also went shopping and chatted with Yajima's beauty salon many times. Because of this friendship caused by their father, the four of them were called "sisters in distress" in their company AVEX.
