TOKYO — On matters of history, Japan and South Korea can never seem to agree to disagree.

Three days after South Korea said it would not roll back a 2015 accord over women forced into sexual slavery for the Japanese military during World War II, Prime Minister Shinzo Abe of Japan rejected on Friday “additional measures” sought by Seoul.

The issue even threatened to jeopardize his attendance at the Winter Olympics’ opening ceremony next month.

Responding to a call by South Korea’s president, Moon Jae-in, for a renewed and sincere apology to the so-called comfort women, Mr. Abe told reporters, “We can by no means accept South Korea’s unilateral request for additional measures.”

“The Japan-South Korea deal was a promise between countries,” Mr. Abe said. “It is an international and universal principle to keep it.”
