I wasn't so interested in merchandising through CD or whatever form. I wasn't really so aggressive about promoting my own work. I had my recordings from the past, but I never thought someone was interested in releasing it.

At the beginning, I felt sort of reluctant about my music from my past. But in the last couple of years, I felt good about what I did in the past. The way I see my work, time passes from the time I performed or recorded a work. When I look at it now, 25 years or 30 years ago, if I see that it has value today, I will agree to release it.

For a long time in the 1970s, I was experimenting to build musical instruments and use them. I did a lot of ethnic music studies and other things, like electronic music. Making homemade musical instruments and performing was my major activity from the time.

I remember, in elementary school, being asked what my father does and not knowing how to answer. When I asked my mom what I should say next time, she replied, "Just say he's self-employed." I love that.

Most of my music is improvisation, and composition is improvisation. Even if I have a score, it is improvisation.

I was an ignored guy and have been for many years. But I suppose I became well-known after being ignored. After the release of the CDs and LPs, especially the LPs, people like it. I was impressed.

I don't think I differentiate between composition and improvisation. Improvisation could be a large part of a composition.
