Noa (乃紫, born in 2000), stylized as noa, is a Japanese singer‑songwriter known for crafting her music entirely on her own, from composition and lyrics to arrangement and production. After studying piano, violin, and guitar during her childhood, she discovered digital music creation at university, which led her to develop her distinctive, self‑produced sound.

She began releasing music professionally in 2023 and quickly gained visibility through social media, especially TikTok, where her 2024 hit “Zen hōkō bishōjo” became a viral success. Her growing popularity led to sold‑out live performances, including her first one‑man show at Shibuya WWW and subsequent concerts in major venues such as Zepp Shinjuku and Zepp Osaka.

In 2025, Spotify selected her for RADAR: Early Noise, highlighting her as one of Japan’s most promising emerging artists. Alongside her solo work, she has contributed vocals and compositions to various projects across television, film, and advertising, collaborating with artists such as MAISONdes, Shingo Katori, UNIS, and ILLIT.
