Ninja Museum Heist

When the Iga Ninja Museum Was Robbed

In August 2020, the Iga-ryu Ninja Museum was robbed by thieves who appeared to take a few lessons in stealth from the very people it celebrates.

There are few places in Japan where a burglary would seem more ironically appropriate than the Iga-ryu Ninja Museum.

Located in Iga, Mie Prefecture, the museum celebrates the history and traditions of Japan's legendary ninja. But in the early hours of Monday, 17 August 2020, it became the target of a remarkably efficient theft.

According to The Guardian, thieves broke into the museum and stole a safe containing more than ¥1 million (£7,155) in cash. The safe weighed approximately 150kg, yet the entire operation reportedly took just three minutes.

A stealthy operation

Museum staff discovered the break-in after an alarm sounded in the early hours of Monday. Police believed the thieves had waited until staff left at around 5:30pm on Sunday before making their move.

According to Japan's Yomiuri Shimbun, the burglars forced open the office door with a crowbar, removed the heavy safe and escaped.

The money inside consisted largely of admission fees collected during the weekend, when more than 1,000 people had visited the museum and surrounding ninja attractions.

But the thieves didn't simply rely on darkness.

CNN reported that security camera footage showed a car arriving at the museum, with a man getting out of the passenger seat and approaching one of the cameras. He then tilted it downwards so that it filmed only the ground for the rest of the night.

The museum's forest setting may also have helped the criminals. Although the secluded location adds to its atmosphere and appeal, it also makes the building largely hidden from view once darkness falls.

No black suits or shuriken

Despite the obvious ninja parallels, there was no evidence that the suspects were dressed like traditional ninja or armed with shuriken.

Nevertheless, the burglary had several characteristics that would not have looked out of place in a ninja story: a secluded location, careful timing, surveillance being defeated and a rapid getaway with a valuable object.

The irony was difficult to miss.

The Iga region is one of Japan's most famous centres of ninja heritage, and the museum allows visitors to explore the history, weapons, tools and techniques associated with Iga-ryu ninjutsu.

Yet on this occasion, the museum itself became the setting for a real-world lesson in stealth.

The burglars may not have possessed the mysterious abilities sometimes attributed to historical shinobi, but they certainly demonstrated planning, deception and speed.

For a museum dedicated to the art of disappearing without being noticed, there could hardly have been a more fitting — or embarrassing — way to lose a safe.
