The Korea Heritage Service and the Overseas Korean Cultural Heritage Foundation said Wednesday that 256-thousand-190 Korean cultural relics were abroad as of January 1.
The figures are based on a survey of 801 museums and galleries across 29 countries, including Japan, the United States and Germany.
The total represents an increase of eight-thousand-472 items from the previous year.
Japan contains the largest number of Korean cultural artifacts, according to the announcement.
Confirmed holdings in Japan totaled 110-thousand-611 items, accounting for 43-point-two percent of all overseas relics.
The United States followed with more than 68-thousand items, Germany with more than 16-thousand and Britain with more than 15-thousand.
