OBVERSE: 'Korea, National Census.'
REVERSE: '
Governor-General of Korea, Showa 5 [1930].October 1.'
Korea was annexed by Japan in 1910, and as a part of the Japanese empire, was subject to the
national census. The official medal for the 1930 Korean census is identical to the Japanese
1920 census medal except for the inscription on the reverse.

I have found two census taker badges for the Korean census. One is dated 1925, but there
doesn't seem to be a commemorative medal issued for that census.

Note that the Korean census medal is much more scarce than the Japanese census medal.
