The Kumho Business Group was founded in 1946 by Mr. In-Chun Park as a small transportation company with two Ford Taxicabs as its only assets. Demand was high and the business grew rapidly, only to be devastated by the Korean War in 1950 to 1953.

After the war Mr. Park started over and built what is today Korea's largest intercity bus transportation company, Kwang Ju Highway Lines, and its largest and finest tyre manufacturer, Kumho Tyres.
