Japanese music in a new light.
ICCHO ISSHI creates original music with shakuhachi, biwa and trumpet. Inspired by Japan’s history and landscapes, the trio brings its music to concerts, events and creative projects.

Shakuhachi · Biwa · Trumpet About usThree musicians.
One sound all their own.Rooted in tradition.Alive in the moment.
Our name speaks to the rhythm between drawing tight and letting go. The breath of the shakuhachi, the resonance of the biwa and the clarity of the trumpet come together in music that feels both unmistakably Japanese and wholly its own.
Whether the setting is intimate or expansive, we want the music to stay with your audience long after the final note.
