On March 11, 2025, IM Mami, a 22-year-old influencer, was stabbed live on stream in Japan. The crime was particularly shocking due to its violent nature, with the victim being stabbed over 30 times. Initial Western media reports portrayed it as a parasocial case or an act of misogyny, but the situation is more complex, involving a history between the victim and the perpetrator.
Iris Sato, known online as IM Mami, was a 22-year-old live streamer on who watch.tv (Foo watch). She had around 2,600 followers and was known for her "just chatting" streams, creative challenges, and community interaction. Kenichi Takano, a 42-year-old man, discovered her stream in December 2021 and became a significant donor, contributing over 100,000 Yen (approximately $1,000 at the time) per month.
In early 2022, after Takano had donated over 400,000 Yen, Sato contacted him directly via the Line app. Starting in September 2022, she began asking him for direct money transfers, initially with excuses like forgetting her wallet. Despite promising to repay him, she consistently asked for more, with the amounts increasing and the excuses becoming more elaborate, such as claiming her sister needed help with a baby.
Takano took out loans from Eiffel and Raichu, two loan companies in Japan, to provide Sato with money. When he revealed his financial situation, instead of advising him to stop, Sato encouraged him to borrow from another company. She even provided advice on how to lie about his income to secure more loans. Takano admitted to falsifying his income and working hours to get the loans, but Sato continued to insist he find ways to borrow more.
Takano was not perverted and didn't ask for anything inappropriate; he simply enjoyed Sato's streams and wanted to help her. Sato emotionally manipulated him, at one point saying she wanted to die if she couldn't borrow money, leading Takano to reassure her. She also expressed "I love you" to him, possibly leading Takano to believe she had romantic feelings for him.
Takano had given Sato over 2.5 million yen, with 1 million yen from creditors. By the end of January 2023, he began asking for his money back, but Sato ghosted him. Despite his financial struggles, he witnessed her success as a streamer and her engagement to someone else. Takano sued her in 2023 and won the lawsuit in December 2023, with the court ordering her to repay the 2.5 million yen with 3% annual interest.
Despite winning the lawsuit, Takano did not receive any money. Sato referenced the lawsuit on stream in a passive-aggressive manner, downplaying its significance. Court records revealed Takano's feelings for her and his desire to help her, while she acted nonchalant about the situation. She continued to earn a substantial monthly income from streaming (300,000 to 400,000 yen) but did not repay him.
Sato's poker account, showing her with a bag of chips worth 542,000 Yen, suggested where Takano's money might have gone. Feeling cornered and betrayed, Takano sent Sato a final message on March 7, 2025, blaming himself for falling in love and being deceived, and pleading for at least 10,000 Yen back. He mentioned taking pills and being depressed, but was ignored.
On March 11, 2025, Sato was streaming in the Shinjuku area. Takano traveled to her location, found her, and stabbed her over 30 times with a 13 cm knife, also carrying two other knives in his backpack. He continued talking to her as she lay on the ground, even asking if she was dead yet.
The incident caused widespread confusion, with some initially mistaking Sato for a voice actress with the same name. Japanese reactions were mixed, with some sympathizing with Takano's plight, while others condemned his violence. Many felt sorry for both the victim and the perpetrator, acknowledging the complexity of the situation. The video concludes by emphasizing that while murder is wrong, Sato was not innocent, having manipulated Takano.

0:00 an incident that has left an entire country in a state of absolute shock on the 11th of March 2025 a 22-year-old influencer by the name of IM Mami was stabbed live on stream in broad daylight Japan it's already quite rare to find a murder in this country but what's even more rare is a violent crime of this nature where the victim gets stabbed over 30 times so it's no wonder that people weren't just shocked they were visibly confused everyone's asking themselves how did this happen what led this person to commit such a violent act but the Publications are asking themselves the same questions with many Western ones like the New York Times not having any of the important details when reporting on it making this out to be
0:45 yet another parasocial case with some even saying that it's another case of misogyny but it's not that simple in fact this incident goes back years she knew the man and had a hand in making him gradually lose his mind up until the this point it doesn't get crazier than this and we're going to talk about everything from the beginning so let's do this so Iris Sato was a 22-year-old live streamer who went by the name IM magami online the website she used to stream was who watch.tv Japanese people typically call it Foo watch she was very active on there and was one of its top performers before passing away she had reached around 2,600 followers which is apparently really big for this website her main area of expertise was just chatting streams talking to her chat and
1:31 interacting with them sometimes she'd do these creative challenges going Outdoors or talking to strangers but in a nutshell for her it was all about her community and speaking of community this is where Kenichi Tako comes in A 42-year-old man who had found her stream and really liked her personality he had found her in December of 2021 and very quickly started to donate money to show his support at his Peak he was donating over a 100,000 Yen a month that is not a small amount of money today being 674 but back then when the yend was Stronger it was closer to $1,000 per month this quickly caught I's attention because at the time she wasn't a full-time streamer yet she was still working at a restaurant after having donated over 400,000 yen to her in the first few months of 2022 I decided to reach out to
2:17 takano directly and message him on the line app this is when they would first get in touch for both of them this was the beginning of the end this is when their problematic relationship would start to take place and now we have access to these convers ations because they leaked after the incident on September 2022 she would start to ask him to lend her money directly not through tipping on the stream directly to her bank account one of the first examples of this was her saying that she forgot her wallet at her job and that she's really strapped for cash saying that she'll pay him back as soon as the next day or the day after she also specified I want the money transferred to the cash card I have at home preferably right now this was at 7:00 p.m. on September 8th 2022 within a minute Tako responded can I just transfer it now asking how much do you need and her saying that she needs a few tens of thousands of Yen but this was
3:03 only the beginning and guess what even though she said that she was going to repay him the day after or the day after that she didn't she only kept asking for more not even 6 days after saying that she had lost her wallet and needed a few thousands to last her for the next day she went ahead and asked for another 20,000 yen but she wouldn't take no for an answer he said he couldn't do it with his card and then she was like well what about what about a direct transfer from your bank account then and Tako would always find a way she would do this almost every week for a while right here asking for 50,000 yen the amount would always keep going up and the excuses would get crazier like for example this is a bad translation but this is her pretty much saying that her sister's pregnant and she can't take care of the baby so she needs money to help her and still Tako would send her money and around more than a month after starting
3:48 to ask him for money not only did she keep insisting things started to get very disturbing Tako would send I a message saying I'm worried and this was in relation to his financial situation after giving her so much money so she responded by saying hey where did you get the money from and here's what he had to say this right here is a bad translation but what he's saying is Eiffel and Raichu two of the biggest and most well-known loan companies in Japan this meant that takano had been taking on loans to send her money whenever she would ask because she was asking so consistently and he didn't have a stable job so what does she respond with she says I want you to borrow from another company different from Eiffel and raiku because I need $50,000 Yen right now arguing that she has loans to pay so she saw that he was indebted to two
4:34 different credit companies and instead of saying you know what you should stop she asks him to get indebted to a third company too and this is when he reveals something even more disturbing he says it's really tough in fact soon it will be revealed that I lied and borrowed it so to get the loan he had to fake his income and other details about his employment and again this was her chance to say you know what let's lay off this I'll find someone else or I'll find another solution no she triples down and says I looked into it and it turns out that if you have a job that qualifies you as a self-employed person or you're receiving the money in a tax-friendly way you can still borrow the money even if you can't prove it so it wouldn't be a lie and then he specified very clearly I lied about my annual income in working hours but the conversation still goes on and she keeps insisting even if you don't have your personal information
5:20 registered as a regular employee you can still pass the screening and it's often impossible to confirm so there's no way they'll find out if it's true or not I went through because I couldn't confirm it so I want to point out the fact that she was an expert at this as if she's done this multiple times before even a financial adviser wouldn't know all this so does beg the question was he her only victim at this point we still don't know he also states that he's been ignoring the credit companies and that he'll probably be getting a lumpsum bill because he's been ignoring them also specifying that the billing address that he put was his parents' house so his entire family was implicated at this point but she just didn't care he says I'm getting scared of lying to borrow money now and then she says there's nothing I can do I did it once and then Tako says so whatever happens happens so at this point yeah you might be asking yourself many questions why is this guy
6:06 doing this well look from all the text messages that leaked he wasn't perverted he never asked for any nudes or anything weird it seemed that he just really liked watching her streams she reached out to him for help and he just couldn't say no but even if he wanted to say no she was very good at emotionally manipulating him as evidenced by these messages look at this he tells her in the beginning of November 2022 that had applied to Raichu right the credit agency to get more money to give to her she replies with yeah with this Emoji takano then says I hope I can borrow it with a cute Emoji 15 minutes later what does she reply with she says I want to die if I can't borrow money Tako says don't say that I replies with I want to do it so this is complete and utter emotional manipulation this is
6:51 disgusting but obviously it gets worse he falls asleep briefly for around more than an hour he says I fell asleep then says I stay alive then she says Tako I can't live without you then he replies with I'm happy me too I I can't live without you and then I'm aami finishes off the conversation by saying thank you as always I love you yeah I don't think it's too crazy to assume that Tako might have thought that she was into him that she I don't know appreciated him as more than a friend maybe that's what he was hoping for but he never really expressed that in text messages he was just always happy to help but then takano's fantasy was cut short when the Creditor s came knocking he had given her over 2.5 million yen and back then that was over $220,000 with 1 million yen out of those
7:38 2.5 million being from creditors so around the end of January 2023 he started asking for his money back at least gradually not all of it at once saying Hey listen tomorrow please start to pay me back I replies with sorry can it be 2 days instead he says well okay fine just please on the 2nd of February then on the 2nd of February he says please deposit what's going on you said on the 2 so I moved it to the second the next day he says please give me the money back and on the 5th of February he says you're not going to pay me back anymore imami then replies this is a really bad translation what she actually said was no I am going to give it back and then Tako says is that so this is when she would pretty much ghost him she would not reply to him anymore 6 days later Tako says I'm barely making ends meat so unless you transfer the money I won't be able to pay anything in advance
8:24 please transfer the money a couple days later I guess I won't get my money back a few days later are you willing to refund the money nothing he was just talking to a brick wall but of course for him it only got worse not only were the creditors after him but he was witnessing her life stream and get a lot of money from live streams while at the same time celebrating the fact that she had found a fiance that she was about to get married and that they both were living in a high-rise apartment together meaning that she was financially well off and yet he hadn't seen a single scent returned from her D was very frustrated understandably and losing a lot of Hope but interestingly enough he saw sought to resolve this legally he had lent her money he was in big financial trouble but in 2023 he sued her in order to get his money back and in December of 2023 he actually won the
9:09 lawsuit the judge had ordered her to pay him back everything he's lent her so 2.5 million yen with an interest rate of 3% per year from December 8th 2023 until the payment is made so the court fully cited with takano he was completely in the right because at the time he had no stable income and was living in poverty so obviously him winning that lawsuit was a relief at least it seemed that way until he realized that it didn't really change much IM magami would start to reference this lawsuit on stream sometimes in a passive aggressive manner saying things like I borrowed money and I'm going to court or the comments from a certain individual saying give me my money back were so awful that I blocked him using the block function she would even say that all she had to do was pay back all the money to get rid of this lawsuit in a nonchalant tone as if it
9:56 wasn't a big deal the reality of these two could not be more different in the court records of this lawsuit takano had said I had feelings for her and wanted to help her if she was in trouble and there she was nonchalantly saying yeah I guess I just have to pay it back additionally since Tako watched her streams regularly he understood that she was making a lot of money through tips and donations she had a platinum badge on Foo watch which meant that she was one of the platform's top streamers there are multiple ranks on this website right and typically when you get to the point where IM Mami was you're making a monthly income of 300,000 to 400,000 yen in donations and still he was seeing nothing even though the court had ordered her to pay him back he was not seeing a single scent but obviously the salt in the wound did not end here she had a Twitter account that is private so
10:42 we don't know much about it but some people found another Twitter account of hers that was fully about poker with the first post she had posted on this account being her holding a bag full of chips worth 542,000 Yen so that could explain where a lot of takano's money might have gone so at this point Tako felt completely cornered he had tried to help someone who he really liked getting indebted to two different companies and living in poverty and even though he had gone through the legal means of getting his money back nothing had changed and he was seeing the same woman who scammed him and played with his feelings continue to stream and Thrive making a lot of money monthly eventually during the year of 2024 something had cracked in him and in 2025 he made up his mind he sent her one final message on March 7th 2025 blaming himself for falling in
11:29 love and being deceived and asking her one last time please give me my money back I'm in the negative because of the Consumer loans I borrowed to lend to you and I can't live asking can you somehow pay me back at least 10,000 Yen which is not even like $100 adding that he'd been taking a lot of pills recently and had been sleeping all day because of how depressed he was but of course he was ignored 4 days later imami had gone live streaming around the Shinjuku area takano saw this recognized the area and decided to go pay her a visit he took o station which was the closest to him and rode close to 2 hours down to Shinjuku she was initially streaming around the takad Baba station but then made her way down to the shin oku station so he took the metro and he followed her this is a map that kind of tells you how it happened he started here he went down
12:15 here she kept walking this way and so then he followed her that way too and that's where the incident took place eventually he was able to make out where she was streaming from so he made his way to her tripod setup and that's where he struck multiple times repeatedly violently with a blank look in his eyes the knife he had used was 13 cm in length he showed up with a backpack and there were two other knives in there as well he had stabbed her over 30 times in the neck in the chest in the shoulder and initially she was screaming help but then went silent and I mean think about that for a second 30 times just doing the same motion over and over again that's not normal right none of this is normal this is very violent and the fact that he had a very blank there made it worse in fact he kept talking to
13:01 her as she was laying on the ground at that point the screen was completely black you could hear sirens in the background and you could also hear him asking her while she lay on the ground are you dead yet while kicking her to say that there was fear and confusion is an understatement the entire place was swarmed with police and paramedics and to add to the confusion people didn't even know who was actually stabbed this tweet right here with almost half a million views said that she was a voice actress and a live streamer stabbed by an anti fan while streaming on the Japanese site who watch imami was not a voice actress she was a live streamer and that's because they were confusing her with a voice actress by the same name this imami was being flooded with emails DMS calls messages thinking that it was her that was stabbed her agency had to put out a statement saying listen
13:48 guys first off condolences to whoever just got killed but please stop flooding my messages it's not me and as you can see this was pretty damn significant seeing that this post has over 30 million views now when it comes to Japanese people the reactions varied greatly very shortly after the stabbing incident people made up a makeshift Memorial but you might have noticed the fact that many of these news outlets their videos that they posted on YouTube are heavily disliked and that's because for some Japanese they're citing way too much with the victim rather than the plight of the person who committed the crime you can see this in the comments with this one having over 2,400 likes saying there's no way you can borrow 2.5 million yen and just say I don't know block I can't approve of M murder but I can understand the feeling of murderous intent this post on Twitter Echoes a
14:33 different statement saying whatever they do to you don't stab them to death reminding people that takano had kicked her when she was down after the stabbing so don't blame the victim he's in the wrong here there was a lot of discussion in the comment section of the article on Yahoo Japan detailing the incident the most upvoted ones echoed the fact that yes they do feel sorry that she had to be murdered but at the same time they felt sorry for the perpetrator so as you can see this is a very complex situation it's not black black and white at all and in the end I think it doesn't have to be I think multiple things can be true at once it's true that murder is too far he is definitely wrong for that but at the same time it's not like she was innocent either she manipulated him hard and she was really good at it making many people wonder if she had done it before and if there are other victims it's just unfortunate that we
15:20 couldn't conclude this without any Bloodshed guys be safe out there and if someone asks you for money know your limits because if it's too good to be true then it probably is okay stay safe out there thank you so much for watching and I'll see you in the next video whenever that is I love you [Music]
