Fuji no Makigari

Fuji no Makigari (富士の巻狩り) was a grand hunting event arranged by shogun Minamoto no Yoritomo in May 1193, centering around the foot of Mount Fuji. A large number of the shogun's "gokenin" (vassals) participated in the event.
Background.
It is said that the purpose of Fuji no Makigari was to show off the authority of the shogun and to carry out military exercise. The hunting event began on the east side of the foot of Mount Fuji (what is currently Gotemba and Susono, Shizuoka Prefecture) and extended to the Asagiri Plateau (currently Fujinomiya, Shizuoka Prefecture) to the west. 
"Azuma Kagami" talks about the hunting event saying, "Such a crowd of archers that there is no point measuring." It is said that countless shogun's gokenin participated.

Incidents.
Minamoto no Yoriie's deer.
On June 16, 1193, Yoritomo's 12-year-old son Yoriie shot a deer for the first time. Hunting was stopped and a festival was held in the evening. Yoritomo was rejoiced by his son's achievement and sent a messenger to his wife Masako, but she sent the messenger back, saying that a military commander's son being able to shoot a deer is nothing to celebrate.
Kudō Kagemitsu.
During the hunting on June 27, a big deer suddenly ran before Yoritomo. Kudō Kagemitsu, who was near Yoritomo, shot at the deer. Kagemitsu, a master of archery, shot up to three times, but missed all his shots. Kagemitsu said, "I have been hunting for more than 70 years since I was 11 years old, but I have never failed to kill my prey. This must be the deer that Yama-no-Kami rides." 
As people were already wondering about the strange incident, the same evening Kagemitsu fell ill and collapsed. Yoritomo thought this was very strange and considered ending the hunting event and returning home. However, after receiving advice from his "shukurō" (wise old men) the hunting continued the next day and for the following seven days.
Revenge of the Soga Brothers.
On June 28, 1193, the Revenge of the Soga Brothers took place at the Fuji no Makigari. The brothers Soga Sukenari and Soga Tokimune murdered their father's killer, Kudō Suketsune. The brothers managed to kill 10 other participants until Suketsune's subordinate Nitta Tadatsune ran up to the scene managed to kill the elder brother, Sukenari. Then, the younger brother Tokimune massacred all the samurai that attempted to stop him and raided Yoritomo's mansion, in an attempt to attack Yoritomo. However, after entering Yoritomo's bedchamber he was finally taken down by Gosho no Gorōmaru, thus ending the massacre and saving the shogun from a possible assassination attempt. After this, Yoritomo took Tokimune in for questioning and had him executed the next day.
