In late 2022, a significant archaeological discovery was made at the Tomio Maruyama burial mound in Nara, Japan.

Among the finds were a 2.3-meter-long iron sword, the longest of its kind from the Kofun period, and a unique shield-shaped bronze mirror decorated with gods and animals.

These items, dating back to the late 4th century, were unexpected and have sparked intrigue about Japan’s early rulers.

The sword’s size challenges conventional understanding, as it is too long to be a practical weapon, the Japan Times has reported.

Experts believe it was a burial offering for a powerful figure, possibly a “minister-level” leader in the Yamato Kingship.

The discovery sheds light on the political and social dynamics of the time and highlights the role of advanced conservation techniques in preserving these historical treasures.
