Zutto Mayonaka de Ii no ni., usually shortened to Zutomayo, is a Japanese rock group that debuted in 2018. Secretive by nature, the group has never released a full member list, crediting different people for arrangements and music video production each time. The only member reoccurring in all of the group's output is the vocalist and songwriter, an unidentified woman referred to as "ACA-Ne".
Despite the little information released, the group is commercially successful. Zutomayo's three EP's have reached 8th, 1st, and 2nd on the Oricon Albums Chart, respectively. The group was also invited to perform at the 2019 Fuji Rock Festival a year after their debut. They have a large fanbase, known as Zutomaro, a name given by ACA-Ne in the Q&A included with the first edition of the EP Imawa Imade Chikaiwa Emide.
Zutomayo gained wider international exposure after their track "Taidada" was featured in Forza Horizon 6.
Style Aside from ACA-Ne, the vocalist, it is unclear how many people are in the band. ACA-Ne has never revealed her face, and the band have performed behind a translucent screen during concerts, including at the 2019 Fuji Rock Festival. Many have pointed to Zutomayo's secrecy regarding its members contributing towards its popularity. In more recent performances however, other members of the band have been less secretive, choosing to show their faces.
Zutomayo typically produces rock music, often featuring intricate, funk-inspired basslines. ACA-Ne's voice has been described as "energetic", "expressive", and "delicate".
History The group debuted with the release of their first song, , via YouTube on June 4, 2018. The song became an immediate hit, garnering 200,000 views within the first week. Additionally, after being released on streaming platforms on August 30, the song became the most streamed song in Japan that week. Following the song's release, Zutomayo held their first concert at Daikanyama Loop in Tokyo. Attendees were handed opaque glasses and reported that the entire venue was dark for the concert's duration. The group would continue to conceal their identities in future concerts.
Zutomayo released two more singles digitally before releasing their first EP, , on November 14 through EMI Records. The EP reached 8th on the Oricon Albums Chart and was nominated in the 19th CD Shop Awards. On June 5, 2019, a second EP was released titled , which topped the Oricon chart.
