Why is bowling a popular sport in Korea?

Answer 1

Korea is a small country (in regards to land) so many of the more popular outdoor sports that Americans take for granted are unavailable. Koreans would rather create sports complexes with available land that has multiple levels and various sports. One of the easier sports to set up was Bowling back in the 70's and 80's when it was gaining world wide attention. Due to this, Koreans who at that time hadn't played many western sports began bowling. Korea by its nature is a competitive place and Bowling encourages that competition. Thus began the tradition of Korean Bowling.
