Company Information

Like a time machine,
Presenting us sounds of more than two hundred years ago,
Dressed in a story that is more dramatic than a novel.
While being artwork like sculpture,
They are supreme handicrafts any high-technology of today cannot reach.
We think old string instruments are cultural heritage
That humankind should hand over to next generation.
They are not just instruments.


That made us reach a concept that we should and would like to
Buy and sell genuinely valuable instruments alone
And to strive for scrupulous repair and maintenance with deep-rooted knowledge and mature skills,
And have been doing so since our foundation in 1980.
We are very grateful that we have gained sympathy from many people for our concept,
And have served many celebrated musicians and music foundations.


Great treasures are instruments, made as long as one hundred years ago.
Could you please have a hand to help them be handed over to next generation?
We are always ready to present you any support.


Hand over genuineness to next generation

Profile of President and Representative Director, Sota Nakazawa

Born in Tokyo in 1984. His father is Muneyuki Nakazawa, a violin restorer, and his mother is Kimiko Nakazawa, a violinist. He was raised up in such a musical family, having opportunities to meet internationally celebrated musicians. At the age of 15, he dared to leave Japan to study in the United Kingdom, where he went to an international school while learning about many prestigious instruments by often visiting the major auction house Sotheby’s and Peter Biddulph Ltd., a worldwide renowned British appraiser, with which experience he made a good base for string instrument business in his teens. After graduating from Faculty of Foreign Studies of Sophia University, he joined Dentsu Inc., the largest advertisement agency in Japan. After some years of sales experience, he worked as a media planner and joined many projects to help development of music and culture. While working for Dentsu, he started a project team “Classic for Japan” (currently a general foundation Classic for Japan) to help development of classical music movement and support young artists. In 2014, he resigned from Dentsu in order to be engaged in music business and activities, and took over the business of Nippon Violin as President and Representative Director. In 2015, he joined Scientific Lab of the violin museum in Cremona City and deepened his expertise of Guarneri del Gesu.
