little by little is a Japanese pop rock duo from Japan consisting of hideco and 田中裕基. Signed to Sony Music Entertainment Japan, the group is known for music that sits between J-pop and pop rock, with melodic songwriting, clear vocal lines, and guitar-driven arrangements that fit naturally into anime theme music.
The duo gained wider recognition through their association with Naruto, which introduced little by little to anime viewers and J-pop listeners alike. That connection remains central to their identity and to their place in the early-2000s anime song scene, where their polished, accessible sound helped them stand out among fans of anison and television themes.
Across their work, little by little balances pop hooks with a straightforward rock edge and a bright, emotional style. The result is a catalog that feels easy to connect with for listeners who discover Japanese music through anime openings and endings, while still reflecting the duo's identity as a pop rock act with a clear focus on memorable melodies.
