The story
Welcome to the Hamaguri Gomon, or the Hamaguri Gate. As you stand before this towering wooden structure on the western edge of the Kyoto Imperial Palace, you are looking at one of the most scarred witnesses to the violent birth of modern Japan. Take a moment to look closely at the heavy wooden pillars and the dark iron plates bolted to the frame.
You will see small, circular indentations and jagged gouges. These are not the result of age or decay. These are bullet holes, left behind from a desperate, bloody firefight that occurred here over one hundred and fifty years ago.
Before we dive into the battle, consider the name: Hamaguri. In Japanese, this means clam. Originally, this gate was called the Shin-zaike Gomon and it was almost always kept tightly shut.
However, during a massive fire in 1788, the heat became so intense that the gate was finally thrown open to allow people to escape. Locals joked that the gate was like a clam that had been put on a grill—it only opened when it was cooked. The name stuck, but the gate’s true trial by fire was yet to come.
In the summer of 1864, Japan was in chaos. The Tokugawa Shogunate was crumbling, and samurai from the Choshu domain, who wanted to restore power to the Emperor, marched on Kyoto. On the morning of August 20th, they reached this very spot.
They were met by the defenders of the palace—samurai from the Aizu and Satsuma domains. This was the Kinmon Incident. Imagine the air thick with the smell of black powder and the deafening cracks of rifles.
The Choshu samurai, led by the fierce Kusaka Genzui, charged directly at this gate, desperate to break through and seize the Emperor. The fighting was hand-to-hand, brutal and chaotic. If you run your fingers along the wood, you are touching the marks of that desperation.
Those dents were made by lead bullets flying through the air as the defenders fired back from behind these very walls. The Choshu forces were eventually repelled, but the cost to the city was unimaginable. During the retreat, a fire broke out that quickly spiraled out of control.
Known as the Great Fire of Genji, it raged for three days, destroying over 28,000 houses and nearly 200 temples and shrines. Most of Kyoto was reduced to ash because of the sparks that flew from this gate. Today, the Kyoto Imperial Palace is a place of profound silence and manicured beauty.
But as you walk through the Hamaguri Gomon, remember that these stones and beams still carry the echoes of the screams and the gunfire that signaled the end of the samurai era. The clam gate remains open now, a permanent scar on the face of history.
