Description
Nasu no Yoichi, also known as Nasu Munetaka, was born between 1166 and 1169 as the eleventh son of Nasu no Suketaka in modern-day Tochigi Prefecture. His epithet "Yoichi" reflects his birth order as the tenth or eleventh son. Historical accounts identify him as a master archer serving Minamoto no Yoshitsune during the Genpei War (1180-1185).

His most legendary feat occurred at the 1185 Battle of Yashima. Challenged by the Taira clan, he struck a fan mounted on a distant enemy ship pole—approximately 70 meters away—while mounted on horseback amidst turbulent waters. This single shot, executed under threat of death, became celebrated in "The Tale of the Heike" and cemented his reputation. He used a kabura-ya, a humming-bulb arrow with a turnip-shaped whistle to ward off evil spirits.

Physically, Yoichi possessed an effeminate appearance marked by long black hair (sometimes depicted as blue), a slim figure, and delicate features that occasionally caused mistaken identity. He typically wore traditional samurai attire: a blue garb, white waist sash, green hair ribbon, and archer's arm guards.

Personality-wise, Yoichi exhibited self-doubt, frequently calling himself "the youngest of the Nasu Clan and the ugliest" among his ten older brothers. He showed compassion, bandaging allies' wounds and sharing land grants with brothers who fought for the Taira. Service under Yoshitsune left him with severe PTSD from witnessing wartime atrocities, causing emotional distress when confronted by memories or his former lord. Alcohol consumption made him unusually talkative about his past.

After the Genpei War, Minamoto no Yoritomo rewarded Yoichi with five private estates and appointed him shugo (governor) of Tottori Castle. He later lost this position after losing a hunting competition to Kajiwara Kagetoki. Following Yoritomo's death, Yoichi became a Jōdo Shinshū Buddhist monk, founded a temple, and died either around 1189/1190 or in 1232 at age 64. His grave resides at Sokujo-in Temple in Kyoto, where visitors pray for "hitting targets" in endeavors like business or exams.

Legends attribute his exceptional archery to rigorous training that reportedly caused physical arm asymmetry. For his military achievements, he received a renowned tachi sword by Ko-Bizen Naritaka; it remained with the Nasu family for roughly 800 years and gained designation as a jūyō-bunkazai (Important Cultural Property) in 1987.
