19-year-old arrested over murder of sex worker at hotel also charged with attempted murder

27 Comments

Police in Tachikawa, Tokyo, have added a charge of attempted murder against a 19-year-old male who has already been arrested on suspicion of killing a 31-year-old sex worker at a hotel this month.

Police said the suspect, who cannot be named because he is a minor, checked into the hotel at 3:30 p.m. on June 1, shortly before the woman, Michi Mamoriya, arrived at 3:45 p.m. It is believed she and the suspect got into an argument because she used the room phone to call her male companion and asked him to come and help her. After that, the suspect stabbed Mamoriya around 70 times, police said.

When her 25-year-old companion arrived, he knocked on the door, then went into the room where he also was attacked. The suspect fled from the hotel, leaving a blood-stained knife in the hotel corridor. The male victim was able to call 119.

The suspect was arrested in Akiruno, Tokyo, on June 2, on suspicion of killing Mamoriya. This week, he was also charged with the attempted murder of Mamoriya’s male colleague.

Police said at a news conference on Tuesday that video footage, taken inside the hotel room before the killing, was retrieved from the suspect's smartphone. In the footage, Mamoriya warns the suspect not to film anything. The suspect then complies with her request, and the footage stops.  

After his arrest, the suspect was quoted by police as saying he pretended to be a client when he arranged the meeting. He said he became “interested in killing someone” after watching a film of people being murdered on the internet. He also told police that “the sex industry is not helping with the declining birthrate and aging population” in Japan.

What a sicko, lock him up for a long time. And yes, under 20 is considered a minor in Japan.

This is overkill, which indicates an element of rage. Foul.

Disgusting. Name protected because this guy, old enough to purchase a knife, hire a sexworker, book into a hotel, have (incorrect) opinions on population control, and execute a human being..... is too young to be named. Gotta protect the kids, y'all. Pure facepalm.

Stabbbed 70 times?!? That is a guy with some serious anger problems!!!

A 19 year old can check into the hotel, have a smartphone, etc *yet, “cannot be named because **he is a minor**”. - Charge him as “an adult***”, remove him from society and lock him up with the adult convicts.

9 ( +11 / -2 )

Still *can’t be named or charged ‘as an adult’ at 19*** in Japan but, **what is legal age for ‘consensual sex’?

"He also told police that “the sex industry is not helping with the declining birthrate and aging population” in Japan."

Well murdering someone doesn't help the declining population, either.

At 19, he can vote, but he cannot smoke or drink and is termed a "minor." Where is the sense in that?

70 times would indicate rage but at that age, what is he enraged from | about? When I was 19 I was having a good time on Waikiki Beach. WTF?

What a depressing story

Release his frickin name

6 ( +8 / -2 )

Good that they didn't release his name. No one who is arrested should have his or her name published until they have been at least charged and arraigned, and possibly not unless they have been convicted. Same for photos. Publishing photos of people who have been taken into custody but not convicted should be probibited.

I wonder what the problem was that she had to call her PIMP for help. But the 20 year old has a point when he said “the sex industry is not helping with the declining birthrate and aging population” in Japan.

Horribly unfortunate that this crazy criminal was not detected and put away before he killed someone, I understand that is not realistic to expect that every sociopath is caught before they cause a tragedy, but this seems like a very clear example of someone deranged to an obvious degree, enough to let someone who knew him alert the authorities.

He also told police that “the sex industry is not helping with the declining birthrate and aging population” in Japan.

Yet he's hiring a sex worker (prostitute) to have protected sex with. Do you SEE the irony there?

Tired of these JT articles hiding the name because he's a so-called minor.Since you can vote at 18,you can have your name put out there for a crime.

Killing people isn’t helping the birthrate much either...

3 ( +3 / -0 )

Nothing will happen to him, as he is 19, and thus a "juvenile" in the eyes of Japanese law. Sad, but it is what it is.

Protect the perpetrator of this crime by not naming him, but perfectly fine for the name of the victim to be blabbed all over the media. Completely upside down rule mentality.

"I wonder what the problem was that she had to call her PIMP for help."

Inside the hotel room, the 19-year-old suspect began to use his telephone to record images of the victim against her wishes...

19yo is big enough to be punished as an adult, stop treating these criminals like kids already and make an example of this garbage.

8 ( +8 / -0 )

A madman, should either sent to jail or to a secure mental ward for life.

Something is seriously wrong within the brain of this crazy guy.

If she was working for a deli health outfit, he was simply there for driving her and for safety in case of trouble. The prices and payment in the places are fixed, and it is pretty lucrative for the women. Nothing do to with your American idea about "PIMP":

Here's your problem. People who tend to immerse themselves in snuff will eventually seek snuff in real life. Unfortunately, stuff like this is hard to crack down on.

He also told police that “the sex industry is not helping with the declining birthrate and aging population” in Japan.

Well, it certainly doesn't help people being murdered with the declining population either. The authorities should lock this guy up for good or in the very least give him a short drop and a sudden stop.

Yes. Long enough to ponder all the wonderful years of his life that he could have achieved and strived for but threw away.
