Under the influence of his grandfather, Sho Asano started playing Japanese drums at the age of 3 and the Tsugaru shamisen at the age of 5. After that, he studied the Odajima Ryu under Tokuo Odajima II(the second person to use the name Tokuo Odajima).

At the age of seven, he became the youngest participant in the Tsugaru Shamisen National Tournament held in Hirosaki City, Aomori Prefecture, and from the following year forward, he broke the record for the youngest winner in each class one after another.  In the 2004 Tsugaru Shamisen National Tournament, he was the youngest winner (14 years old at the time) in the highest level of A-class. He then went on to win three consecutive championships until 2006. He will be inducted into the Hall of Fame according to the rules of the tournament.

In 2007, at the age of 17, he made his major debut with "Shokaze" from Victor Entertainment. Since then, he has given concerts at the Concertgebouw (Netherlands) and the Kennedy Center (USA), as well as concert tours in the United States, Europe, Canada, and other Asian countries.

With a performance style that is not bound by genres such as folk songs, classical, rock, jazz, pop, and flamenco, he has performed with various artists such as Sayuri Ishikawa, Yosuke Yamashita, Kazushi Miyazawa, and yama. When he was in junior high school, he was in a band with former BOØWY member Makoto Takahashi (drums).

On his own albums, he has also worked with world-class musicians,  Will Lee (bass guitar), Marcus Gilmore (drummer), and Richard Stoltzman (clarinet).  In addition, as a traditional Japanese instrument player, he performed in “Monster bash,” which is the biggest music festival in Japan.

 These days, he joined “NOBODY KNOWS “supported by the Agency for Cultural Affairs.  He is also actively engaged in the development and dissemination of Japanese culture. In addition, he has participated in the "MIKAGE PROJECT," which composes and arranges folk songs from various parts of Japan with a modern sensibility. He is opening up a new music scene such as "ART Kabuki Orchestra," which consists of several Japanese musicians.

His favorite shamisen is "Shitan" by Sangi Kobo.  In 2023, he signed the world's first endorsement contract with Sanki Kobo, one of Japan's leading shamisen makers. In recognition of these activities to disseminate Tsugaru shamisen, which is traditional culture of Japan, to both Japanese and international audiences, Asano's activities were officially approved as a part of the official government program "BEYOND 2020" from the first year of 2019.

In addition to pursuing original folk songs and classical performing arts, he is a noble young Tsugaru shamisen player who pursues the potential of the Tsugaru shamisen in order to convey the shamisen to a wide range of generations.
