Watanabe no Tsuna

Watanabe no Tsuna (渡辺 綱) (953-1025) was a Japanese samurai, a retainer of Minamoto no Yorimitsu (also known as Raikō), one of the earliest samurai to be famed for his military exploits.

In legend

Watanabe features in many of Yorimitsu's legendary adventures, and aids him in fighting many monsters, beasts and demons.

In one such tale, Tsuna accompanies Raikō to the hut of Yamamba, a man-eating hag. There they find a boy known as Kaidomaru, who had been brought up among animals and endowed with superhuman strength. The boy requests that Raikō allow him to become one of his retainers, and Raikō accepts, giving the boy the name Sakata no Kintoki, often shortened to Kintoki.

Some of Watanabe no Tsuna's other comrades in legend are Urabe no Suetake and Usui Sadamitsu. Together, the four are collectively known as the Four Guardian Kings, an allusion to the Buddhist Shitennō. Watanabe is also said to have assisted Raikō in slaying a tsuchigumo.

His most famous feat is the defeat of the demon Ibaraki-doji, the principal follower of Shuten-doji. He fought Ibaraki-doji single-handedly at the Rashomon gate at the southern end of Suzaku-oji, the central North-South street in the old capital Heian-kyo (now Kyoto).
