Empress Jingu

According to the Nihon Shoki, Empress Jingu led a naval expedition to the Korean peninsula and conquered the kingdoms of Silla, Baekje, and Goguryeo. This legendary campaign is said to have established Japanese dominance in Korea for several centuries, though archaeological evidence is lacking.

After her legendary conquest, Empress Jingu is said to have returned to Japan with tribute from the Korean kingdoms, including gold, silver, and textiles. This event is recorded as a triumph that enriched the Yamato court and solidified her reputation as a warrior ruler.

Empress Jingu is said to have served as regent for her son, Emperor Ojin, after her husband's death. Her regency is credited with maintaining stability and continuing the expansion of Yamato influence, though the historical accuracy of her rule is disputed.
