The South Korean government has called on Japan to correct misleading claims in its school textbooks.
Tokyo approved several textbooks on Tuesday that make incorrect claims about the Dokdo islets and Japanese atrocities against Korea.
Seoul's foreign ministry made it clear that the Dokdo islets belong to South Korea historically, geographically and under international law.
It also expressed strong regrets over Japan omitting the coercive nature of its wartime sexual enslavement and forced labor when describing those acts.
Seoul urged Tokyo to educate its young people in accordance with the same spirit of sincere apology and self-reflection that Japan itself had expressed.
The ministry has summoned a senior official at the Japanese embassy in Seoul to deliver a formal protest.
