Taira no Masakado: Rebel Guardian of Tokyo

In the heart of Tokyo’s bustling financial district, nestled between gleaming skyscrapers, lies a quiet, unassuming stone monument. This is the grave of Taira no Masakado, a 10th-century samurai whose spirit is said to influence the fortunes of modern Japan. He was a rebel who declared himself the “New Emperor,” and his story is a dramatic tale of ambition, rebellion, and a curse so powerful that it commands the respect of business executives to this day.

Who was Taira no Masakado?

Taira no Masakado was a prominent samurai warrior of the Heian period and a descendant of Emperor Kanmu. His life took a dramatic turn from loyal courtier to the leader of a major rebellion.

From imperial servant to rebel leader

Born in the early 900s, Masakado initially served the imperial regent Fujiwara no Tadahira in the capital. He later returned to his home in the Kanto region, where disputes with his relatives over his inheritance escalated into armed conflict. To consolidate his power, he was involved in the killing of several of them between 931 and 936.

Rise and fall of the New Emperor

Feeling disconnected from the distant rule of Kyoto’s imperial government, Masakado launched a full-scale rebellion in 939, known as the Tengyō no ran. He began by attacking a central government outpost in Hitachi Province and went on to conquer several other provinces. In a move that shocked the imperial court, he declared himself the “Shinnō” (New Emperor), establishing a new kingdom in the Kanto region.

The Kyoto government’s response was swift and ruthless. They placed a bounty on his head, and in 940, he was defeated and killed in battle by the forces of Fujiwara no Hidesato and his cousin, Taira no Sadamori. Masakado was decapitated, and his head was taken to Kyoto for public display as a warning to any other potential rebels.

In a show of gratitude for his victory, Hidesato offered the bow and arrow he used in the battle to the Kameido Katori Shrine, naming them “Kachiya,” or “winning arrow.” This event is still commemorated today in the annual Kachiya Matsuri (Winning Arrow Festival) held on May 5th at the shrine, featuring a procession of people dressed as victorious warriors.

Vengeful spirit and business guardian

The story of Taira no Masakado doesn’t end with his death. His spirit’s journey back to his homeland is the stuff of legends and has had a lasting impact, especially on Tokyo’s business world.

Why do people still visit Taira no Masakado’s grave?

You’d be amazed at how many people visit the grave. Whenever I’ve walked past it, there has always been someone offering prayers. It’s not long until the next person or group arrives. This deep respect stems from a unique mix of historical legend and persistent superstition. In Tokyo’s Otemachi financial district, Taira no Masakado is revered out of a belief that his spirit must be appeased for business success and safety.

This reverence is rooted in several factors:

The vengeful spirit legend: After his execution, legend says his severed head flew back from Kyoto to his home region, eventually landing in a fishing village that would become part of modern-day Tokyo. Over the centuries, his spirit became associated with misfortune and mysterious accidents for anyone who disrespected or tried to move his grave, known as the Kubizuka (head mound).

An amulet for success: The area around his grave is now prime real estate. Businesspeople from the surrounding financial institutions frequently visit to pray for protection and prosperity, viewing him as a guardian deity (kami) of their ventures.
Fear of the curse: The belief in his curse is deeply ingrained in the local business culture. Rumors persist that surrounding office buildings have no windows overlooking the grave. I’ve been there, and this isn’t true. Another story claims that executives avoid sitting with their backs to it. One bank even opened an account in his name, used by a volunteer group for the grave’s upkeep, showcasing the deep-seated respect (or fear) for the legend.
A symbol of resilience: To some in the Kanto region, Masakado is also respected as a “hero of the people” who stood up against an oppressive government. This narrative adds another layer to his potent spiritual presence in the heart of modern Tokyo.

What does his grave look like?

Taira no Masakado’s grave, the Masakado no Kubizuka, is a simple stone monument tucked into a secluded green space. You’ll find it adorned with offerings of flowers, incense, and sake, and surrounded by numerous frog statues. Everything is snuggled in between skyscrapers!

In Japanese, frogs are called “kaeru,” which also means “to return.” The word is a pun in this case. According to legend, Masakado’s head hopped like a frog on its journey back to the Kanto region.

Photography tips

Skyscrapers surround the grave, so be prepared for shadows. Also, as the site is historically and culturally important, be respectful. Make sure to avoid photographing worshippers.

You’ll often see a caretaker looking after the grave’s upkeep. To avoid any issues, I have always checked with him if taking photos is okay. He’s never said no to me; in fact, he’s been quite enthusiastic about it.

The legacy of a rebel samurai
