Ruka Mochizuki's New Milestone with 'Wagamama'

Ruka Mochizuki, the rising enka star, has made headlines once again with her latest single 'Wagamama'. Released by Nippon Columbia on July 23, 2025, this track has secured the number one position on the Oricon Weekly Enka and Kayokyoku Single Chart as of August 4, 2025. This achievement marks her third number-one single following her debut work 'Shitsuren Bojo' in 2020, and the second single 'Omokage, Mirenbashi' in 2021.

The creative genius Tetsuya Komuro, who has been a prominent figure in the music industry, took on the roles of both lyricist and composer for this single. Notably, 'Wagamama' is Komuro's first work to achieve the number one ranking in the enka genre, underlining the versatility of his music. The arrangement has been skillfully handled by Shinji Miyazaki, who has produced numerous hits in the enka scene.

Tetsuya Komuro expressed his excitement about working with Ruka, stating, "Diversity is key; more artists are now interpreting my songs in various ways, and Ruka is one of them." This sentiment was echoed by Mochizuki, who expressed her appreciation for Komuro’s congratulatory message upon the single's success. "I was filled with emotion when I received his warm message saying 'Congratulations on the first place!'. It makes me incredibly happy to see more people recognizing the charm of enka through 'Wagamama'."

The song features a modern and delicate melody that conveys love, seamlessly integrated into the enka framework thanks to Miyazaki's arrangement. With her smooth and transparent voice, Mochizuki introduces listeners to a new realm of enka music that resonates with a younger generation.

Looking ahead, Ruka Mochizuki will be appearing on the TBS program 'Prebato!!' on July 31 (Thursday) at 19:00, where she will showcase her watercolor painting skills, adding another layer to her artistic persona. The WHY HOW DO COMPANY group is committed to supporting artists and revitalizing the enka genre, creating new values through their music initiatives.
