[7] Hako'ō hated priesthood and escaped from Hakone, relying on his uncle by marriage, Hōjō Tokimasa, whose late wife was the daughter of Sukechika.

Tokimasa bestowed the kanji "toki" (時) in his name upon Hako'ō, giving him the imina name Tokimune.

[10] According to Soga Monogatari, as his last words, Sukenari told Tokimune, "go and present yourself to Lord Kamakura [Minamoto no Yoritomo] unwaveringly."

However, he was apprehended by Yoritomo's strong retainer Gosho no Gorōmaru in the mansion, preventing him from attacking the shogun.

[13] Although at first Yoritomo considered sparing his life, Tokimune was executed that day on June 29, 1193, at the request of Suketsune's son, Itō Suketoki.

[8] In ancient accords Azuma Kagami and Soga Monogatari, after killing Suketsune, Tokimune also attempted to attack shogun Minamoto no Yoritomo, which is interpreted as a result of Hōjō Tokimasa's secret maneuvers.

Tokimasa had entered Suruga Province and Fujino in advance, before Yoritomo, as a preparation for his secret plan.

[15] Hiroyuki Miura,[16][17][18] along with many others have debated that it was through Tokimasa's strong relation to the Soga brothers that led Tokimune to attack the shogun.

There is another set of graves located at Jōsen-ji temple of the Soga Manor[19] (in present-day Sogayatsu, Odawara, Kanagawa Prefecture)[20] where the brothers grew up.

However, there are numerous other graves located around Japan dedicated to the Soga brothers' spirits, which are seen as goryō (vengeful ghosts).
