Serizawa Kamo Biography

Childhood and training

The Serizawa family is a goshi, a high ranking country samurai from Serizawa village near Mito. Kamo's childhood name is Genta, and he has two older brothers and a sister. He studied the ideas of Mitogaku and kenjutsu at Mito estate.

Tengu-to period

Kamo was a priest of a Shinto temple in Kimura family, whose daughter he married, taking the name of Kimura Keiji. In 1860, he joined an extremist anti-foreign group, the Tengu-to, responsible for the assassination of the tairo Ii Naosuke. He made a reputation for himself and climbed up the hierarchy. At the beginning of 1861, he had three members who had broken the rules beheaded.

Very quickly, the Bakufu hunted down and imprisoned the members of the Tengu-to for their participation in the assassination of Ii. Serizawa was released at the end of 1862, and from Kimura Keiji he became Serizawa Kamo, and joined the Roshi gumi of Kiyokawa Hachiro.

Serizawa Kamo Death

On September 18, 1863, after a celebration, Serizawa, drunk, returned to Mibu with Hirayama Goro and Hirama Juusuke. He was executed in his bed with his mistress. Hirayama is killed and Hirama runs away. The executed men were buried in an official ceremony and bandits were accused of the crime.

Those who were chosen to take part in the plot were undoubtedly trusted men of Kondo and Hijikata. Hijikata and Okita took care of Serizawa, Yamanami, Inoue and Harada took care of Hirayama and the surveillance. It is highly unlikely that Kondo himself was involved.

There were a number of theories about the motive for the assassination.

• Serizawa's behavior was too erratic, so the Aizu clan secretly ordered Kondo and Hijikata to assassinate him. This is the most widely accepted theory. Many violent incidents support this idea.
• The Aizu clan suspected the Mito clan of placing Serizawa at the head of the Sonnō jōi struggle. The three Ishin Shishi domains (Mito, Chōshū, and Tosa) were competing with each other in terrorist actions against the Bakufu. Aizu feared that Mito would use the Shinsen gumi to tip the balance in their favor in Kyoto.
• Kondo and Hijikata used Serizawa's connections with Aizu, and then decided to take over the group. It is likely that Kondo and Hijikata hated Serizawa in the first place, but they probably would not have been able to form the Mibu roshi gumi without Serizawa's brother's close relationship with the Aizu clan.
