He attended the University of Colorado at Boulder where he was active in the Asian American Equal Opportunity Program (EOP).
Miyoshi is also the first North American Taiko maker to laminate staves with finger joints and carve out the interior of the nagodo in order to improve the quality of the sound.
A set of Miyoshi's taiko is on display in the Musical Instrument Museum in Phoenix, Arizona.
[3] Miyoshi believes that, “Drums from all traditions have a spirit that is alive and vibrant.
This spirit comes alive through the joining of wood, skins, metal and other materials that come from the trees, plants, animals and the earth…When all of these elements come into harmony and relationship, with good thoughts and actions, a new life is brought into the world.”[4] He brings this philosophy to drum building, and each Miyoshi taiko is made with respect for the raw materials and closed with a prayer.
