The Sojin piano company had its roots in South Korea. It was established in the mid-20th century, specifically in 1954, by the Korean entrepreneur Soo Chul Kim. Under his leadership, the company quickly gained a reputation for producing quality pianos. Sojin pianos are considered as historical relics, with some enthusiasts and collectors seeking these instruments as a testament to the company's legacy in the piano industry. While the Sojin piano company is no longer active, its instruments remain an important part of the broader narrative of piano manufacturing, especially in the context of South Korea's contributions to the world of music and craftsmanship.
