Daisuke Hasegawa is a Japanese guitarist, born on February 15, 1982, best known as a member of Aqua Timez. In the band, he is associated with its melodic rock sound and with the guitar parts that help shape its emotional, vocal-driven arrangements.
Through Aqua Timez, Hasegawa is tied to a project that reached a broad audience in Japan and also connected with anime fans through the group’s anime-related tie-ins. That place in the wider J-pop and anime music landscape is important, because guitar-driven band music often overlaps with opening and ending themes, and Aqua Timez became part of that crossover.
Hasegawa is primarily recognized for his work inside the band rather than as a solo artist, but his role remains central to Aqua Timez’s lineup and to the identity of its signature sound. His guitar work helps define the balance of melody, atmosphere, and energy that listeners associate with the group.
