What triggered the Ikedaya raid?
It began with a man arrested days earlier.
Furutaka Shuntarō ran a fuel business in Kyoto while working as a loyalist agent, and was found to be holding weapons and correspondence. The Shinsengumi seized him and, by contemporary accounts, tortured him at their headquarters.
From that interrogation came intelligence of a plot: to set fires across Kyoto on a windy day, seize the emperor in the confusion and carry him to Chōshū. This is the version that has been repeated ever since.
How much of the plot was real is genuinely uncertain. Confessions extracted under torture are unreliable, and later accounts had every incentive to inflate the danger. That the activists were planning some action to recover their position is clear enough; the scale and specificity claimed for it are not.
What happened at the Ikedaya
Unable to locate the meeting, the Shinsengumi split into two parties and searched the city.
Kondō's group found it. He is said to have gone in with only about four men against more than twenty inside. The fighting was ferocious, and the cramped interior worked against the defenders, who could not use their numbers.
Hijikata Toshizō's party arrived after the fighting had started and sealed the exits.
Among the activists killed were:
- Miyabe Teizō (Kumamoto) — a senior figure in the loyalist movement and an associate of Yoshida Shōin
- Yoshida Toshimaro (Chōshū) — a Shōka Sonjuku graduate ranked with Takasugi and Kusaka
- Kitazoe Kitsuma (Tosa)
The Shinsengumi also took casualties. The story that Okita Sōji collapsed during the fight is widely told, though the cause and timing are disputed.
Consequences of the Ikedaya incident
The Shinsengumi's reputation
The raid turned an obscure patrol unit into the most feared body in Kyoto. Rewards came from both the court and the shogunate, recruitment expanded, and the corps grew rapidly.
It also made them the permanent object of loyalist hatred. Every subsequent year of the Shinsengumi's existence carried the risk of reprisal.
It provoked the Kinmon incident
The more consequential effect was on Chōshū.
Losing capable men in Kyoto inflamed the hardliners in the domain. The following month Chōshū marched on the capital and fought Satsuma and Aizu around the imperial palace — the Kinmon incident.
Chōshū lost and was declared an enemy of the court. From there followed the first shogunal expedition, the Satsuma-Chōshū Alliance, and the collapse of the shogunate.
The Shinsengumi acted to preserve order in Kyoto and accelerated the fall of the government they served. That is the irony of the Ikedaya.

Is the Ikedaya still there?
The building does not survive. A stone marker reading "site of the Ikedaya disturbance" stands near Sanjō Kobashi in Nakagyō ward, Kyoto.
The Sanjō area concentrates several sites from the period. The Ōmiya, where Sakamoto Ryōma was assassinated, is within walking distance.
Frequently asked questions
When was the Ikedaya incident? On the night of 8 July 1864.
Who carried out the Ikedaya raid? The Shinsengumi. Kondō Isami's party entered first; Hijikata Toshizō's arrived later and secured the perimeter.
Why did the Shinsengumi attack? Intelligence obtained from the arrested activist Furutaka Shuntarō indicated a plot in Kyoto, though the reliability and scale of that plot are debated.
Why did the incident make the Shinsengumi famous? Because a very small party overcame a much larger group, and both the imperial court and the shogunate rewarded them for it.
For the men who led the raid see Kondō Isami and Hijikata Toshizō; for the unit see the Shinsengumi.
