Remembering Ken-Chan, the Cat Who Spent Seven Years Trying to Break Into a Japanese Art Museum

Japan is mourning Ken-chan, the black cat who spent seven years trying to slip past the sliding doors of the Onomichi City Museum of Art.

His death, announced on November 11, sparked a wave of tributes from fans who adored his gentle persistence and charm.

Ken-chan became a regular sight at the museum entrance, where visitors often watched security guard Sadao Umayahara crouch into a gentle, playful stance as the determined cat approached.

Their quiet back-and-forth turned into a cherished ritual that spread joy far beyond the museum steps.

His first appearance came in 2017 during a cat-themed exhibition. Living at a nearby restaurant, Ken-chan casually approached the museum, only to be politely blocked by Umayahara.

Staff filmed the moment, and the clip went viral, launching the story known as ‘the cat and the guard standoff.’

Despite his determination, Ken-chan didn’t seem drawn to the exhibitions at all. What he wanted was Umayahara.

Strangely, he only tried to slip inside on the guard’s workdays. Umayahara appeared just four times a year, yet Ken-chan always seemed to know exactly when to show up.

In 2018, Ken-chan began showing up with an orange tabby later named Gocchan. The pair turned the museum steps into their playground, often attempting a two-on-one ‘battle’ against the ever-patient guard.

Their visits became a small but steady source of joy for the community.

Ken-chan fell ill in 2025 and eventually stopped appearing at the museum doors. After months of treatment, he passed away in September 2025.

The museum announced the news on November 11, the anniversary of his adoption, sharing the loss on behalf of his owner.

To honor his legacy, the museum released a 2026 memorial calendar filled with moments between Ken-chan and Umayahara, which sold out right away.

They also created life-size figurines of Ken-chan and Gocchan, and a small black cat sticker now marks the doors he once tried to enter.

Umayahara, who had only ever kept a dog, said Ken-chan was the only cat he had ever grown close to. He admitted he still expects to see the black cat appear around the corner.

“I want to say thank you to him for all the good memories we had together,” Sadao Umayahara said.
