South Korean Foreign Minister Yun Byung-Se will visit Japan this weekend for the first time since taking office, Tokyo said Wednesday, as the two countries mark 50 years of diplomatic relations despite current strains.

Yun will meet his Japanese counterpart Fumio Kishida on Sunday to discuss the bilateral relationship, North Korea and other topics, the foreign ministry said.

He will also attend a ceremony Monday at the South Korean embassy to celebrate half a century since relations between Tokyo and Seoul were normalized, it said.

Yun and Kishida held talks in March in Seoul, but Yun has not been to Japan since being appointed in 2013. Relations have been severely strained by rows over history and territory.

Japanese Prime Minister Shinzo Abe may also attend the embassy event, according to media reports.

Abe has made numerous offers overtures to South Korean President Park Geun-Hye, offering to hold summits, but has been rebuffed since the two came to power in late 2012 and early 2013 respectively.

Park has said there can be no meeting until Japan makes amends for its wartime system of sex slavery, which saw as many as 200,000 mostly South Korean "comfort women" forced into servitude for Japan's Imperial military.

Japan and South Korea are also at odds over ownership of the sparsely-populated Dokdo islets, which sit in the Sea of Japan (East Sea) and are controlled by Seoul. Tokyo claims them under the name Takeshima.
