In the wake of recent controversies surrounding new history textbooks, it has been confirmed that Japan is making distortions about ancient Korean history as well.

In an apparent bid to promote the ‘theory of Imna Nihon-fu,’Japan’s Agency for Cultural Affairs on Wednesday was found to have mislabeled the excavation sites of relics from Korea’s Three Kingdoms era on its Web site.

Describing a gold crown, a sword decorated with a dragon and a wing-shaped crown ornament, from Changnyeong, South Gyeongsang Province in South Korea, the Japanese agency claimed that they were excavated from the Imna region of Korea.

The theory has been widely rejected among Korean and Japanese scholars as it argues that the island country established a military outpost in the Imna region in the ancient Korean kingdom of Gaya and ruled over the territory from the fourth to the sixth century.

The Tokyo National Museum, which possesses the Korean relics, likewise states that they were excavated in Changnyeong, South Korea.
