Leaders of South Korea and Japan Vow to Seek North Korean Denuclearization During Busan Summit
It looks like President Lee has the Japanese leadership bought into his fantasy of denuclearizing North Korea:

President Lee Jae Myung held summit talks Tuesday with outgoing Japanese Prime Minister Shigeru Ishiba in the southeastern city of Busan, where the two leaders reaffirmed their commitment to the complete denuclearization of the Korean Peninsula and to cooperate amid a shifting global trade order.
The meeting came about a month after Lee’s visit to Tokyo, marking the first visit in 21 years by a Japanese leader to a location other than Seoul.
In their third meeting, Lee said Seoul and Tokyo should face history while pursuing “future-oriented” cooperation to address shared challenges, such as low birth rates and an aging population.
You can read more at the link, but at this point I can’t believe any of these world leaders are stupid enough to actually think Kim Jong-un would give up his nukes. Denuclearization seems more like a talking point than an actual diplomatic strategy at this point.
