A 37-year-old man has been arrested on suspicion of attempted murder after he broke into the home of his ex-girlfriend and mixed nicotine into her toothpaste.
Police said Yuki Yanagi, a company employee from Koto Ward, Tokyo, is suspected of breaking into the apartment of the woman in her 30s in Ota Ward on Sept 24, 2023, using a duplicate key, and attempting to kill her by mixing nicotine into her toothpaste and putting liquid mercury on her pillow, TV Asahi reported.
According to police, Yanagi had purchased the nicotine and mercury online in quantities that could have been fatal. After brushing her teeth, the woman experienced symptoms such as numbness in her hands and feet, but recovered. She did not use the pillow after noticing that it was discolored.
The two had reportedly discussed breaking up about a week before the incident.
During questioning, Yanagi partially denied the charges, saying, "I didn't do it with the intention of killing her. I just wanted to make things difficult for her.”

This jerk deserves a long stretch in the slammer.

If everyone could go through breakup 10 times before age 25, it might numb and remedy the problem of harassing, stalking, and killing ex’s.

Stupid is as a stupid does...

James Bond style...what about a tarantula under the sheets ?

Another of Japan's sneaky Pete, though this one is particularly and spectacularly despicable because the target wasn't even assymetrically more powerful than him.
I truly wish all of Japan's sneaky Pete would grow a set and confront their grievances in a more direct manner.

Well now you've made things difficult for yourself

I didn't know that adding nicotine to toothpaste could kill you. I guess you learn something new every day.

Blah, blah, blah...

No wonder she wanted to break up. The guy is obviously not someone you want to be with. The last key he sees should be the one locking him in his cell for a decade or so.

Maximum creep. Horrible.

Lock him up for at least ten years. But this is Japan; bow, suspended sentence, we'll be hearing about her soon after.

Glad she is ok. It definitely sounds like he tried to do more than "make things difficult for her".
GuruMick
Give him work as a crime fiction writer...obviously has the talent and imagination.
He could type in prison

How did he get the nicotine into the toothpaste ?
Talents like this ....could be useful in the Secret Service.

This is why it always pays to have good parents and a close-knit set of friends who will help to steer people away from such actions. Doing something bad to take revenge against someone who broke up with you will only make their decision seem more valid and make you regret it. By doing nothing and moving on, you'll have no regrets, and make the other person have to live with their decision.

Patkim.....but how did he get the nicotine in the toothpaste !!!

Simple. In the story above, it says they had an argument before officially breaking up. Before that, he made a duplicate key, and thus when they officially had broken up, he went in when she wasn't there, and then put it in.
Now if he had people he could talk to or confide in, like good friends, or family he could feel comfortable talking with, they could empathize with him and make him forget about it. But I guess he didn't, so the breakup stewed inside his head and he couldn't let go of it.

This man has a sick fantasy and is dangerous. To be dumped by your female friend should never result in such hateful actions. He is harming himself severely too, no job anymore and face a prison sentence. For what?
I understand men if dumped by a female friend they are reacting more sensitive than most people might think and feel deeply hurt. It also takes a considerable while to find another female friend and dating as a man, it might also cost him quite a lot of money. To approach women for friendship is not easy and often frustrating if rejected countless times.
In contrast women have very little problem if a male friend is breaking up. It's much easier for them to get over it. Up to about 45 years old, there are always many more men than women registered in every dating site and with introduction agencies etc.. Just waiting and plenty of men will show up by themselves.
However such an unlucky situation cannot be an excuse or justification for what he did. If a woman dumps you and does not want you anymore, there is nothing what you can do about it. Stay calm, pack your things and leave and forget her. Try to start - despite it is not easy - a new life with entire new people.

This is a very kind and friendly advice, but I can tell you, for men it will not work. It's not only about women, but about almost every personal problem you might face as a man in your life.
So-called good friends and also co-workers will just laugh about you, expect also some scornful remarks considering you as a loser, and about family hardly any help - parents are not so young anymore and siblings and relatives often have not much contact among each other, and the man himself will remain silent anyway, because being worried to be belittled. As a man in most cases you have to overcome your problems by yourself, alone.
If you look up the social situation, most people who commit suicide are men, most people in prison are men, most people homeless are men ... and not only in Japan but worldwide.

Ah, but no man is an island, or should not be. Sure, you don't have to have many friends, or close family members, but having a few good people you can talk to and socialize with helps. IMHO, those who do commit sick acts like these, tend to be those who refuse to have real deep social bonds with others. Interacting with people is healthy and necessary to help develop healthy communication. Even having the ability to simply greet your neighbors, or start chatting with people you encounter at work, at the store, etc., goes a long way to helping build up your self-esteem and ability to interact with others.

As a Japanese coworker told me recently, the Japanese people think outside the box ONLY when they are trying to harm or injure somebody. Their imagination and originality then really becomes world class.
