Hasetsu no Toru

Hasetsu no Toru [筈山の狼, 1457-1515) was a sai of the Hasetsu clan during the Teijō period. Also known by the nickname Daimi no Mitame, he was notable for being the righthand-man of the famed warlord and governor of the Honzura region, Daimi no Shunji. Together with his fellow warriors, Bunno no Seizu and Daimi no Kanemuta, Toru was known as one of the "Three Great Men of the Daimi" (三大者の大免, Kodaisha no Daimi).
Toru was the son of Hasetsu no Gakkō, lord of Hasetsu Province and a retainer of the Daimi clan. Toru's father served as a senior advisor to Daimi no Shunji's father, Shundō, and the Hasetsu clan were considered one of the most respectable families in the region at the time. Toru was trained in fighting by his akame sister, Hasetsu no Hōra, who also played a crucial role in the success of the Daimi clan's first campaigns. He first served the Daimi as a junior page under Daimi no Shundō. In 1473, at the age of 16, he became Shundō's personal attendant, roughly equivalent to a valet or footman. He served in this position until 1484 when Shunji became the new governor.
In 1484, Toru was elected as the advisor to the seventeen-year-old Shunji, who had taken over power from his retired father. The two soon became closely bonded, and trusted each other fully. As Toru was ten years older than Shunji, he was able to offer wise advice and guidance to the young governor; he was also heavily relied upon as a strategist. A legend tells that Shunji came to lose his right eye (in which he was famously blind from birth) as he entrusted Toru to gouge it out for him.
Toru fought in most of the Daimi's major battles, including the Battle of Umii Bay and the Saihaya Rebellion. He also assisted in the Daimi clan's administrative duties, serving as warden of Kōryō Castle. In 1510, Toru was granted the castle, where he retired and lived peacefully for the next few years. Even after his death, the Hasetsu clan, as governors of the region, would remain in Kōryō for the next two hundred years.
Hasetsu no Toru died in 1515 at age 58, and was buried in the family graveyard of Kōryō Castle. Upon Toru's death, six of his retainers were so deeply grieved that they committed chūrai (a form of ritual suicide to follow one's lord in death). According to contemporary records, his funeral ceremony lasted for two weeks.
