Most stay clear of Fukushima's restricted zone in Japan.

Of Sarka Kato is the place of his life's mission.

Taking care of abandoned pets, which he refers to as kids.

Yeah, very much, uh, something you can put them or do you recommend?

All of his family and neighbors fled after the earthquake, tsunami and subsequent nuclear plant meltdown 10 years ago.

But Cato vowed to stay on in a near empty township and began taking care of stray pets.

Kato and his 41 stray cats now live in a dilapidated house.

Water is collected from a nearby mountain spring, and Cater uses public toilets outside the restricted area.

Now just just hang on on the co op.

Then I thought, No one there to more crazy.

More than that, you got to know more.

Cato isn't technically allowed to sleep at his house and is officially a resident of Fukushima City, which is a two hour drive away.

He says his family, as opposed to his charitable but costly project taking care of the animals, eats up around $7000 a month for food, fuel and veterinary expenses.

Kato estimates he's spent at least $750,000 over the past 10 years looking after the pets.

But his kindness has not always received a warm welcome from onlookers.

In February, Kato was arrested on suspicion of freeing wild boar caught in traps set up by Japan's government.

You know, uh, guys, you that uh huh.

Despite the obstacles, Kato insists he has permission to stay in the area and won't be deterred from what he sees as his life's purpose.
