Arirang Lighter made in Japan

On the front of the lighter is "I CORPS GP"   "OFFICERS OPEN MESS"   "UI JUNG BU CITY"    "KOREA"

On the back of the lighter is a map of Korea with several cities named.

I believe this lighter is from the Korean War from 1950-1953

Lighter made by Tai Yang Ind Co

Japan is stamped on the back of the box.  This lighter is in the original box.  Only on corner of the box has a tear.
