Despite the high acclaim he received in the hogaku, or traditional Japanese music world, for his accomplishments, Agatsuma did not rest on his laurels.
He not only continued to explore the traditional aspects of his instrument, but also avidly experimented in fusing its sounds with diverse musical genres.
In BEAMS, his second album (released in July 2002), he recorded ten original works, taking the Tsugaru-jamisen in new directions.
Currently he is broadening his field with over 100 annual concerts, sessions and media appearances both in Japan and overseas, while continuing to pursue "the traditions of and innovation in the Tsugaru-jamisen."
Agatsuma's song Tsuki Sayu Yoru was included by Fitgirl Repacks as an installer tune for many pirated video games.
