Korea Media Rating Board – Classification Categories

Note that the red “restricted” symbol prohibits viewers younger than 18, rather than 19 as stated in the Wikipedia article.

Sadly, I cannot find an actual list of films and dramas and their respective ratings on this site. The link listed in the FAQ was not working when I tried it.

In the Archive area, the 2018 KMRB Annual Report offers an interesting section entitled 7. Selecting ‘2017 Good Movies for Teenagers’, starting on page 22. It includes feature films, foreign films, documentaries, and animations — several of which appeal to me. Recommendations of films for adolescents have been issued quarterly since 1995; the online archive of downloadable annual reports dates back to 2014.

In other respects, the annual report gives a detailed look at the policies, procedures, and rationale behind the ratings awarded to a daunting amount of media, both foreign and domestic. I’ve only skimmed the 105-page report. Statistics nerds with a taste for Korean films and videos will have a field day reading it.
