Early life Kokona Akiyama was born on December 6, 2005 in Tokyo, Japan. They began singing at age nine, and felt that their deeper tone was appealing, so their vocal teacher then recommended rapping. They also started taking lessons at Avex Artist Academy while in elementary school.

Career In 2017, Cocona passed the audition for the XG Project, led by Simon Jakops, and trained under Xgalx. They said their trainee period was "filled with new and hopeful moments" that taught them about music, personal growth, teamwork, and community. In November 2022, Cocona was featured in the performance of “Galz Xypher” alongside Jurin, Harvey, and Maya, which went viral for their trilingual rapping over instrumentals by JID and Rosalía.

In 2023, Cocona and Maya co-wrote “Show You Can” for Street Woman Fighter 2, their first major songwriting credit. The song was performed live for the first time during XG’s The First Howl World Tour finale at Tokyo Dome in 2025. In February 2026, Cocona was named a brand ambassador for Gucci and appeared on the cover of Elle Japan for its April issue, modeling Gucci clothing from the La Famiglia collection. They attended the 2026 autumn-winter collection show in Milan, Italy, along with fellow brand ambassadors Jay Park and Lee Know.

Artistry Cocona has said their role model is American singer Lauryn Hill. They have also named TLC, Billie Eilish, and Doja Cat as some of their biggest inspirations. Cocona is also a fan of the South Korean group BigBang, singing their song "Haru Haru" for Kirachare 2017.

Personal life Cocona has said that they´re "drawn to unique patterns, distinct colors, and unconventional clothing styles, vintage fashion and visiting thrift stores." Later, they told BuzzFeed they had many reasons for shaving their head and wanted to show those meanings in their future work.

On their 20th birthday, Cocona came out as transmasculine and non-binary in an Instagram post shared on XG’s official account, also stating they had top surgery earlier in the year and expressed gratitude to their XG bandmates, Simon Jakops, and their parents for their support. The announcement received international media coverage and widespread support from fans and the industry. After they came out, XG’s initialism, Xtraordinary Girls, was reinterpreted as Xtraordinary Genes.
