Tuki., a female singer-songwriter and first-year high school student, appeared on the 75th NHK Kohaku Uta Gassen(General TV and others), which was broadcast on New Year's Eve 2024. This was her first appearance on Kouhaku, and when she was introduced as being 15 years old, it sparked a buzz on social media with comments such as "15 years old?! Seriously? That's so amazing...", "She doesn't have the singing ability of a 15-year-old", and "It's amazing that a high school student can sing that well on her first Kouhaku".
Tuki.'s debut song "Bansanka" (2023), which he wrote and composed when he was in the third year of junior high school, became a huge hit. The song surpassed 400 million streaming plays in December last year.
Since she works without revealing her face, the stage was designed so that her face could not be seen, and she sang "Bansanka" in a sailor uniform. After singing, she said, "I was really nervous, but it was fun to sing on such a wonderful stage. Next year, I want to work hard so that I can do music activities in more different ways."
On X (formerly Twitter), "tuki." became a trending topic, with comments such as, "I wonder if she knows her classmates?", "I'd get goosebumps if that girl in my class was tuki." and "I just want to know how she responded when her classmate asked her to go to karaoke."
