Korea and Japan have seen relations dip in recent months due to lingering historical disputes, but the two countries, along with the United States, may meet for talks next week.
Sources in Seoul say the presidential office of national security is looking into the possibility of holding trilateral talks on the sidelines of the Nuclear Security Summit in the Hague next week.
It cited thawing relations between Seoul and Tokyo as the reason.
Last week, Japanese Prime Minister Shinzo Abe pledged to honor a previous government apology to Korean women who were forced into sexual slavery during World War II.
President Park welcomed Abe's remarks the following day and said his decision was "fortunate."
The Japanese prime minister continued his overtures to Seoul earlier this week, when he called Korea Japan's most important neighboring country, one that shares the same strategic interests and basic values.
A government source adds that the United States' continued pressure on Korea and Japan to resolve their differences has also played a role in the possible trailateral summit.
If the talks do take place, possible topics include North Korea's nuclear program, the state of affairs in the North after the purge and execution of Jang Song-thaek, and other issues of mutual interest in Northeast Asia.
