Help bring cat killer to justice – call on Japan to strengthen anti-cruelty laws!


A horrific incident of animal cruelty recently occurred in Japan. A man named Makoto Oya slaughtered more than 13 cats by torturous methods, including burning them with a gas torch and pouring boiling hot water over them.

Despite the fact that he inflicted so much suffering and tore away so many lives, the current law of Japan sets very low punishments for violations of its animal welfare act. In most cases, criminals like Makoto Oya are released from prison with only a financial penalty.

To help bring these heartless murderers to justice, we ask that you please participate in the campaigns below:

Demand that Makoto Oya be sentenced to prison:



Demand an amendment to Japan’s animal welfare law, strengthening punishments for cruelty to animals:

We believe that each and every signature we collect will help to raise public awareness of this issue, thus bringing us a step closer to a legal amendment strengthening the 1973 Act on Welfare and Management of Animals.

Makoto Oya’s mass murder of cats

On August 27, 2017, suspect Makoto Oya, a tax accountant in Saitama, Japan was arrested for violation of the animal welfare act.

Makoto Oya was arrested on suspicion of catching cats with steel traps baited with food that he set in his yard, and slaughtering them using methods such as pouring boiling hot water over them again and again, and burning them with a gas torch.

According to the Metropolitan Police Department security section, suspect Makoto Oya slaughtered more than 13 cats over the course of a year and a half until April 2017, and uploaded videos of his crimes on a “Dislike animals thread” on Japan’s anonymous BBS site 2channel.

On the “Dislike animals thread,” members self-described as animal abuse lovers watch movies of animal slaughter for enjoyment, and post comments about how to kill animals. Suspect Makoto Oya was famous among them, and even addressed by other members as “God.”

The animal abuse lovers requested suspect Makoto Oya to slaughter cats in specific ways, and each time he committed a killing his method became crueler.

Even after his arrest, suspect Makoto Oya said, “it was pest extermination so it is not against the law,” and not only does he not regret the crime but he considers what he did justified.

Penalty examples for animal abusers in Japan

Under Japan’s current animal welfare law, animal abusers are subject to imprisonment of two years of less, or a payment penalty of two million yen (about $18,000 USD) or less, but most cases to date have been sentenced with a payment penalty only or stay of execution.

Animals have been slaughtered meaninglessly, but mere monetary fines are given as punishment!

For example, Naoto Kitagawa taped the feet of a kitten, made it eat hot sauce, and crushed it to death in front of its mother by forcefully rubbing and pressing it, but was released with a payment penalty of 200 thousand yen by summary indictment.

And Jun Matsubara, who slaughtered a cat by cutting its ears, legs and neck, was sent to prison, but for only a short period of six months. There have been comments on his SNS that he has been killing cats again since his release.

Both Naoto Kitagawa and Jun Matsubara had posted videos and photos of their slaughter on the “Dislike animals thread,” just as suspect Makoto Oya did.

Problems with the current situation in Japan

1.) The weakness of current punishments for animal cruelty

The 1973 Act on Welfare and Management of Animals imposes penalties of two years’ prison time less, or a payment penalty of two million yen or less.

Because the maximum prison sentence is only two years, it may be subject to a stay of execution. Besides, nobody has actually been sentenced to imprisonment for two years, one year being the longest sentence served so far.

Since Makoto Oya is a tax accountant, a fine of two million yen will mean nothing to him, and provide little in the way of deterrence.

2.) The continued existence of the “Dislike animals thread” on the BBS site 2channel

On the popular site 2channel, there is a BBS for people who enjoy animal abuse, “Dislike animals @2channel BBS”

All videos that are thought to be Makoto Oya’s have been shared on this BBS. Members “praised” the torture movies, made requests for what kinds of video they wanted to see, and the torture escalated every time.

The presence of this sort of BBS is certain to give birth to the next Makoto Oya.

Comparison between Japan and countries abroad

Quoted and translated from

United Kingdom:

10 billion yen is donated to animal protection every year in England, and with very few exceptions, animal shelters do not euthanize potentially adoptable animals.

An act on animal welfare was passed in the 18th century, proving how high the level of awareness towards animal welfare is in the U.K.

I feel that the success of animal welfare causes in England showcase a strong humane spirit. “Humans and animals are equal, with the same rights to live. Human matters must not avoid the rights of animals.”


Protection facilities for pets called tierheims exist in Germany, and the number of shelters that permit euthanasia of adoptable animals is a surprising zero. Some tierheims have up to 600 volunteers, and are financially supported 90% or more by donations. There are also animal police, comprised only of people who have passed strict training and tests, and they possess the same authority as ordinary police officers.

We strongly feel that governmental and civil help is necessary to achieve the goal of zero animal euthanasia.
