He received a master's degree in sculpture from Tokyo National University of Fine Arts and Music in 1969, and in 1970 received a fellowship from the Italian Government to study at the Academy of Fine Arts in Rome. He moved to Italy and established a studio in Pietrasanta, a town that since the 15th century has been known for its marble quarries, and once supplied marble to Michelangelo.
In 1992, Yasuda partnered with Bibai on a project to promote arts and culture and revitalize the city. That partnership became the Bibai Art Plaza, a 17-acre sculpture park of woods and lawns, surrounded by mountains and a river. Forty of Yasuda's sculptures are exhibited in the park.
Yasuda's work has been exhibited extensively throughout Italy and Japan. It has also been installed in museums and public spaces around the world, including the Champs-Elysées in Paris, France; the Garachico in Tenerife, Spain; at Aurora Place in Sydney, Australia; and the Yorkshire Sculpture Park in West Bretton, the United Kingdom.
