Hiroshi Iizuka is a Japanese master craftsman of violins and violas who heads a workshop in Philadelphia.

Early life

He was born in Maebashi, Japan, in 1945.[1] After graduating from college in 1968, he worked various jobs in Tokyo before pursuing instrument making.[2]

In 1971, he began an apprenticeship with Soroku Murata, founder of the Tokyo Violin Making School.[3] From 1973 to 1977, he trained in Mittenwald, Germany, under Josef Kantuscher and received a journeyman’s diploma from the German Chamber of Handwork in 1974.[1]

In 1976, Iizuka received a gold medal and Certificate of Merit at the Violin Society of America competition in Philadelphia. He received additional certificates at later VSA competitions, including in 1982.[3]

Career

Iizuka established his workshop in Pennsylvania in 1977, and his work gained broader recognition after violist Emanuel Vardi purchased one of his instruments in 1982.[4]

According to Strings Magazine, Iizuka builds approximately 10 to 12 instruments per year, primarily violas.[5] He has made more than 380 instruments since beginning his independent practice.[1]

Musicians known to have played Iizuka instruments include Michael Tree of the Guarneri Quartet and Ori Kam of the Jerusalem Quartet.[3][6]

His instruments have been referenced in discussions about modern versus historical Italian instruments. Violinist Giora Schmidt, who plays an Iizuka violin, participated in a widely reported double-blind study comparing modern and antique violins.[7]

Instrument design

Iizuka's viola designs incorporate structural modifications intended to balance tonal depth and playability.

Viola d’amore-inspired model

Beginning in 1979, Iizuka developed a model incorporating design features inspired by the historical viola d'amore while adapting the instrument for modern viola setup and technique.[3]

Rubenesque model

Introduced in 1992, the Rubenesque model incorporates shortened corners and a modified lower bout to reduce perceived playing length while maintaining body resonance.[1]

Personal life

Iizuka moved to the United States in 1977 with his wife, Daniela Stern.[4]
