Japan's "Instant Poop Method": Dumb Title, Surprisingly Real Results

A college student's self-taught constipation trick gets the variety show treatment — and the comment section turns into a live clinical trial.

What's going on

Detective! Knight Scoop (探偵!ナイトスクープ) is a long-running late-night variety program from Osaka's ABC Television, on the air since 1988. Viewers send in requests — strange phenomena, personal mysteries, things they've always wondered about — and the show's panel of "detectives" goes out to investigate. It's beloved for treating even the most absurd requests with complete sincerity, and for occasionally stumbling into something that turns out to be genuinely meaningful.

This particular segment begins with a request from a 22-year-old college student in Kanagawa Prefecture. She has suffered from severe constipation her entire life — hours on the toilet, rabbit-pellet results, the works. But in high school, she stumbled onto something: if you consciously "feel" your intestines, your poop, and your butthole all at once, things start moving. Immediately. She calls it the Shunkan Unko-hō — the "Instant Poop Method" — and she wants the show to verify whether it actually works, or if she's just been fooling herself.

To test her discovery, Detective Maeta — the show's go-to investigator for anything scatological — assembles a remarkable panel: women who had previously appeared in Knight Scoop episodes, all with their own bathroom-related submissions. Among them is a participant known from an earlier segment about unusually smelly farts, as well as comedian Kintaro. The results, both on screen and in the comment section, turn out to be more persuasive than anyone expected.

They’re treating this like a joke, but honestly someone should properly research this lol
アホな話みたいに扱ってるけど、しっかり研究した方がええやろこれw
This might genuinely be an incredible invention
これまじですごい発明なんじゃないの
“Intestines, poop, and butthole” — it falls into a 5-7-5 syllable rhythm, annoyingly easy to memorize (In Japanese, the 5-7-5 structure is the same cadence as haiku, which gives a phrase a naturally catchy, memorable feel.)
「腸とうんことケツの穴」が七五調でめちゃくちゃ覚えやすい

The replies pile on with other famous titles that share the same rhythm — the classic ballad “Sake, Tears, Men and Women,” the beloved ’90s hit “A Room, a White Shirt, and Me,” and “it has the feel of a Sheena Ringo album title.” The point being: this phrase has no business being this easy to recall.

I’m genuinely amazed by Detective Maeta’s ability to connect buttholes to Takashimaya (Takashimaya is one of Japan’s most prestigious luxury department store chains — not exactly the first association that comes to mind.)
ケツの穴と高島屋を結びつける真栄田のセンスに驚いてる。
Given that some people get seriously ill — or worse — from constipation, this is actually a wonderful discovery
便秘で体調を悪くする方や最悪亡くなる方がいる中素晴らしい発見だと思います
Being the most delightfully unhinged show in the Kansai region (Kansai is the western Japan region centered on Osaka and Kyoto, known for its distinctive comedy culture), it never gets old no matter how many times you watch
関西を代表する頭のおかしい番組だけに何回見ても飽きへんな
Unexpectedly practical content lmao
意外と実用的な内容で草
Knight Scoop previously helped middle-aged men deal with post-urination drip too. Absolute legends.
過去にはおじさんの残尿対策にも貢献してくれたナイトスクープ 最高です
The title sounds ridiculous but if someone actually studied this properly it could probably be applied in clinical settings lol
タイトルは馬鹿らしいけど研究すれば病院でも実用化できそうな内容w
I literally can’t go when people are around, so if someone was making noise right outside the door I would not be producing anything lol
私は人が居ると出ないから、ドア前で騒がれたら絶対出ない笑
First time I’ve ever seen someone burst into tears just from meeting Kintaro (Kintaro is a comedian known for her uncanny impersonations of idol group dance routines) — although I then realized this is also just the first time I’ve seen Kintaro meet a regular person face to face
キンタローに会えて泣く人初めて観たな。と思ったけど、そもそもキンタローが素人と対面するみたいなの初めて観たことに気づいた。
TO EVERYONE WITH CONSTIPATION, PLEASE HEAR THIS!! Combine this with raising your left foot (put it on a step) and leaning your upper body backward — it seriously works!! My family has been doing it for years!! SPREAD THE WORD!!
便秘の人に届いて!!! これ+左足を上げる(台にのせる)+上半身を後傾させていくとマジで出るよー!! 実家直伝!!届いて~!!!
So many people get embarrassed just talking about bodies in health class, yet here they are as adults being completely open about it 😂 And not just talking — actually demonstrating right there on the spot, which is the best part
学生のときは着替えや保険の授業で恥ずかしがる子も多いのに、社会に出るとここまで開けっぴろげに話せるようになるの好き😂 しかも話すだけじゃなくすぐ隣で実践してるの最高
I happened to be constipated so I tried the method and it genuinely worked, everything came out smooth! This thing has immediate results
丁度便秘だったのでこの方法実践したら、確かにスルッと出た! 即効性あるわこの方法
The fact that she’s a woman in her 20s and took this all the way to a TV request is genuinely impressive
20代女性でこの企画取り組んでるのが凄い
It’s a full assembly of legends, yet the subject matter is, well, this lmao
レジェンド大集合なのに内容が内容すぎて草
Has this many past requesters ever been assembled in one place before????? The fact that this has reached academic conference level is wild
こんなに過去の依頼者が 揃った事ある????? 学会レベルに達してるの凄い。
This is genuinely, non-ironically a significant discovery isn’t it 😂
これマジで冗談じゃすまないぐらい凄い発見なんじゃない?😂
Whenever a request involves anything even slightly below the belt, Detective Maeta gets assigned at a suspiciously high rate. And yet it somehow feels completely reassuring.
少しでもシモを感じる依頼は真栄田探偵に投げられる率が異常に高い気がする。 しかし謎の安心感がある
That colorful girl has basically become a semi-regular at this point lol
最近あのカラフルな子準レギュラーになってるやん笑
Six days’ worth… that must be quite the volume
6日分て量凄そうやな
What IS this Avengers lineup
なんだこのアベンジャーズ
Ah, the Loo-vengers
あ、便じゃ
The Poop-vengers
オベンジャーズ

Both replies are puns on “Avengers” (Abenjaazu in Japanese) — swapping in “ben” (便), which means poop. The phonetics get a bit lost in translation, but you get the idea.

No but genuinely, this might be the invention of the century
真面目に世紀の大発明じゃね?
Now I’m worried about the pipes being the next thing that gets clogged lol
今度は配管のほうが詰まってそうで心配w
2:38 Having to smell someone’s fart after six days of constipation is a genuine form of hell 😂😂😂
2:38 6日便秘の屁かがされるなんて地獄やん😂😂😂(笑)
I just love women who are completely unfiltered like this
なんかこんくらい振り切ってくれる女性たち好き
The bad-smell person sure shows up a lot lol
悪臭の人、出演率高くて草
Wait — so the reason that person’s farts smell so bad was because of constipation this whole time? That’s a full circle plot twist
おなら臭いやつの原因便秘やんけ 伏線回収かよ
Her boyfriend was basically getting a direct hit of heavily concentrated fumes the whole time. Poor guy lol
彼氏さん、うんこを直で嗅がされよるよーなもんか。可哀想に笑
Knowing he was getting hit with six-day-marinated air this whole time… I genuinely feel for that man lol
彼氏さん6日漬けの空気嗅がされてたと思うとかなり同情する笑
I went in half-expecting lowbrow content, but everyone on screen was so genuinely wholesome that every trace of that feeling just vanished
けつの穴で感じる!? とかしょうもないこと思ってたけど出演者全員バケモンで下い気持ち全部飛んでった
There is not a single human being alive who has never had a problem with their poop
うんこに悩んだ事無い人間は 世の中に1人もいないと言い切れる
This is absolutely an Ig Nobel Prize candidate (The Ig Nobel Prizes are awarded annually for research that “first makes people laugh, then makes them think.” Japan has won numerous times.)
イグノーベル賞候補やろこれ
What looked like a joke segment turned out to be a genuinely helpful how-to for people dealing with a very real problem
ネタと思いきや切実な悩みに苦しむ人を救う素晴らしいメソッド動画だった
Something about standing next to those cheerful, outgoing women makes Detective Maeta start to look like the normal one w
この元気で明るくて面白い女の子達と一緒にいると、真栄田探偵が割と普通の人に見えてくる不思議w
Never a bad episode when Detective Maeta is on the case 😊😊
眞栄田探偵の時はハズレがない😊😊
This should be presented at a proper academic conference!
これは、学会で発表するべきです!
You could genuinely charge admission for a workshop on this ☝️
これ、講習会開いて金取れるレベルやで☝️
There are genuinely people out there who are going to be saved by this
マジで救われる子いるやろ!
I happened to be struggling with constipation right now and desperately needed this!! It’s so bad my body is just permanently in crisis mode. Going a full week without anything isn’t unusual for me 😭😭😭 👇️👇️👇️👇️👇️ «« RESULTS »» 💩 A little came out!!‼️‼️‼️‼️‼️‼️‼️‼️
今丁度、便秘で悩んでてどうにか出したかったから助かる!!!!!! まじで、便秘すぎて一生ケツの穴が切れる。1週間出ないこともザラなんよ😭😭😭 👇️👇️👇️👇️👇️ 《 《結果》 》 💩少し出た‼️‼️‼️‼️‼️‼️‼️‼️
Congratulations 🎉
おめでとう🎉
The energy of that comment lmaooo
コメントの勢いで草

My take

It looks absurd at first glance, but constipation is something a lot of people genuinely struggle with — which makes this one of the more quietly useful requests the show has probably ever handled. And watching the women on screen be so completely at ease with the subject, without any forced awkwardness, makes you realize the show itself is what creates that kind of space. That's not nothing.
