The leaders of South Korea, the U.S., and Japan will sit down for a trilateral summit on Wednesday in Spain, on the sidelines of a NATO summit.
No such trilateral summit has taken place for the past five years or so amid strained ties between Seoul and Tokyo.
Yet, relations between the two Asian neighbors have shown signs of improvement since Yoon took office as South Korea's president, pledging to improve ties with Japan.
While there was speculation that Yoon could hold a one-on-one meeting with his Japanese counterpart in Spain, no such meeting, whether in the form of an official summit or a pull-aside meeting, is likely to take place.
During the scheduled trilateral summit, the three countries are expected to discuss an array of issues, including the security situation on the Korean Peninsula.
There are a total of 14 diplomatic functions scheduled for Yoon in Madrid, including the NATO summit, during which he will underscore the importance of the denuclearization of North Korea.
While Seoul is not a member of the military alliance, it has been invited as a partner along with other countries such as Japan, Australia and New Zealand.
Yoon is also expected to hold a series of bilateral meetings with leaders from Canada, Poland, the Netherlands, and Denmark to discuss ways to expand economic cooperation.
First lady Kim Keon-hee plans to accompany Yoon on his first overseas visit.
She plans to attend sessions for the leaders' spouses and other events including a guided tour of the royal palace as well as a dinner with Korean residents in Spain.
