In 1878, ten years after the fall of the Tokugawa Shogunate, Katsu Kaishu published a short, poignant narrative of tumultuous events that occurred between the fall of 1856 and around mid-1868. These events, in which Kaishu was either directly involved or witnessed directly or indirectly, informed modern Japanese history, and therefore influenced Asian and world history. The narrative is entitled Danchonoki (断腸之記) which I translate as “Heartrending Narrative.”

Katsu Kaishu, “the shogun’s last samurai” of my book Samurai Revolution, was a keen observer of human behavior. He had a deep understanding of human nature and, I think, the human condition. He was a prolific and penetrating writer, for which I am very grateful. One of my favorite quotes from his writing is the last line of the Epilogue of “Heartrending Narrative”:

“An old saying has it that one should not tell his dreams to an idiot. I reverse that to say: Only an idiot tells his dreams.”

Last week I wrote a little about Katsu Kaishu’s father, Katsu Kokichi. According to Kokichi’s autobiography, he studied sword-cutting techniques under Yamada Asaemon VII—also aptly known as “Asaemon the Beheader” (“Kubikiri Asaemon”). Eight consecutive generations of the Yamada family, each bearing the given name Asaemon, performed executions for the Tokugawa Shogunate. They were not retainers of the shogun, but rather possessed the indecorous position of unofficial executioner at Edo. The official executioner was a retainer of the shogun, who presumably preferred not to perform the hideous job. So the government hired the Yamada family to do it. Occasionally Yamada was called upon to perform a cutting test after an execution. When his clients obtained a new sword, they needed to confirm that it was sharp enough to cut through the tough sinews and hard bone of the human body. The corpses of executed criminals were used. Kokichi must have been a fast learner. “One day I performed a cutting test,” he wrote. “I cut through the torso. Since my son was at the palace [at Edo Castle], I didn’t have to take care of him.”

On a grimmer note, Yoshida Shoin, the great revolutionary hero of Choshu, was beheaded by Yamada Asaemon VII, under Regent Ii Naosuke’s crackdown against his enemies.
