Koma-mawashi performancesEdit

Although koma-mawashi (駒回し) is traditionally a children's play activity in Japan, Tada performs this art at an expert level and includes in his act elements of juggling, yo-yo and magic, with some comedy thrown in. He is a regular performer at many festivals in the St. Louis, Missouri area, such as the Missouri Botanical Garden's Japanese Festival, Missouri History Museum's International FunFest, Queeny Park's International Folk Fest, and Tower Grove Park's Festival of Nations.[1]

Hiroshi Tada was born in Kyushu, Japan, but lives in St. Louis, Missouri, in the USA.[2] Tada is an affiliate professor of mechanical engineering at Washington University in St. Louis[1] and co-author of Stress Analysis of Cracks Handbook.[3]
