Korea's Foreign Ministry summoned Hisashi Michigami, a senior minister at Japan's embassy in Seoul over the weekend to protest Tokyo's recent move to advance its territorial claims over Korea's Dokdo Island.
Korea is up in arms over a Japanese official's attendance at a ceremony on Saturday that claims Dokdo, which Japan calls Takeshima, is Japanese territory.
A vice minister attended the ceremony, held in Shimane Prefecture to celebrate Takeshima Day on February 22nd, to reassert Tokyo's claim.
Seoul has repeatedly said that having government officials participate in the event would seriously impact Korea-Japan relations, as Dokdo is Korean territory and is under Korean jurisdiction.
To counter Tokyo's move, Seoul's foreign ministry released a video promoting Korea's sovereignty over Dokdo on its website and YouTube this weekend.
The website also includes a link to an animated film about Tokyo's wartime sexual enslavement of Korean women during World War Two.
The ministry plans to bring the so-called "comfort women" issue to the UN Human Rights Council in Geneva next month.
