The records that I recently found indicate that a lot of overseas teams visited Korea for rugby in 1980s.
It includes NZ (80), HK (83), Scotland (84), Wales (85), Cambridge University (86), Australia (New South Wales County, 87), the US (Life University School of Chiropractic,87), Ireland (87), and England (Cambridge University, Cornwall County Side, Combined services, Public School Wanderers, England Students, 87)
This must have been the reason why Korea rugby flourished from 1980 winning the Asian Rugby Championship three times consecutively at that moment (86,88,90).
I also found an intereting video showing that the Royal Navy team played the Korea Air Force Academy in 1960 (KAFA winning 9-0).
