What Japan Thinks: ‘You Taught Us This’ — Japan Pushes Back on SNS Face-Hiding ‘Trend’

Members read ad-free. Subscribe · Log in

Overall verdict A polite but firm ‘what are you talking about’. The Yahoo News headline framed face-hiding on SNS as a curious new youth phenomenon worth investigating. The replies, on both X and Yahoo News itself, refused the framing in near-unanimous fashion. The most-engaged X reply, with 2,362 likes, called the act of posting one’s face on social media the abnormal behavior, full stop. The second-most-engaged, with 1,108 likes, was even more pointed: this is the result of every adult, every PSA, every school program telling kids not to put their faces online. Why is anyone surprised? Underneath the irritation are real concerns about reverse image search, digital tattoo permanence, lookism, and stalkers. A separate strand engaged with the article’s secondary point: the shift from ‘likes’ to ‘saves’ as the metric that matters reflects a real cultural rewiring of what social media is for. And several of the angriest comments asked the journalist a direct question: when can we see your face?

What the tweet was about

On May 4, Yahoo!ニュース picked up a Shueisha Online feature about Japanese youth posting on SNS without showing their faces. The piece pitched the practice as a new behavior worth decoding: ‘they want their photos to look good but don’t want to be perceived as approval-seeking,’ it summarized, and noted that ‘saves’ have replaced ‘likes’ as the engagement metric young people care about most.

Within hours the post drew 212 X replies and over 200 Yahoo News comments. The framing did not survive contact with readers. The dominant reaction across both platforms was that face-hiding isn’t a youth trend at all, just a basic privacy posture that most Japanese internet users of every age already practice, and that the article was asking the wrong question.

The pushback echoes earlier UJ coverage of how Japanese internet culture has long defaulted to anonymity, in contrast to the real-name-and-face norm dominant in Western platforms.

The two most-liked X replies, with 3,470 likes between them, both reject the article’s premise. One says posting your face is the abnormal behavior. The other points out that every adult in Japan spent the last twenty years telling kids not to put their faces online — and is now writing surprised articles when they comply.

@YahooNewsTopics むしろSNSに顔載せる事が異常だと思う 身バレなんて不利益しかないのに、芸能人や店以外でやってるのは頭がどうかしてる

[Yahoo] BeRealは加工や作り込みを前提としないアプリだそうで会社などの内部写真をSNSに公開して問題になってますが若者がプライベートで使う場合でも顔を隠していても写真の内容をしっかり確認しないままアップしてしまうと周囲の情報からアップ主の身元が特定されやすいでしょうからリスクのあるアプリだと思います。
“BeReal is supposed to be an app where photos aren’t edited or staged. There have been incidents where employees uploaded internal company photos to it. Even when young people use it privately, even with their face hidden, if they don’t carefully check the photo content before uploading, the surrounding information often makes it easy to identify the poster. It’s a risky app.”

@YahooNewsTopics う〜ん 承認欲求と思われたくないから顔を隠してアップする? いや、それ自体承認欲求なかったら出来ないのでは? ただの身バレ対策じゃないですかね。
“Hmm. They hide their face because they don’t want to be perceived as approval-seeking? But hiding requires posting in the first place — which is itself approval-seeking, isn’t it? It’s just basic doxx prevention.”

[Yahoo] 今の時代は顔写真から画像検索もできるのだからプライバシー保護の観点から当然の配慮かと思います。むしろ堂々と顔を晒しているのを見ると大丈夫?と心配になります。少なくとも子供などについては顔や個人が特定されるような画像は出すべきではないと思ってます。
“Reverse image search exists now, so this is a sensible privacy practice. If anything, it makes me anxious to see people boldly exposing their faces. At least when it comes to children, faces and identifying images really shouldn’t be put online.”

The journalist should show her face first
[Yahoo] 取材・文/鮫島りん。じゃあ記事書いてるお前がネットに顔を出してみればいい。名前で検索しても顔写真が出てこないってことは出してないんだろう。なぜ出していないのか、それ自体がみんながネットに顔を出さない理由だ。記事にすることすらバカバカしい内容、そもそも記者の名前も偽名っぽいし
“‘Reporting and writing by Sameshima Rin.’ OK, well, then YOU put your face on the internet. Searching your name doesn’t bring up a photo, which means you haven’t either. Why you haven’t is exactly the reason everyone else hasn’t either. It’s silly to even write the article. The reporter’s name itself looks like a pen name.”

Likes vs saves: a real cultural shift
[Yahoo] いいねより保存数を重視するというのは、今のSNSのリアルをよく捉えているなと感じました。昔は私がここにいるという証明でしたが、今は私のセンスを通したこの空間を見てほしいという、いわば自分のアカウントを雑誌の1ページのように編集している感覚なんでしょうね。顔を隠すことで、誰が写っているかというノイズを消し、場所や雰囲気という情報の純度を上げている。
“Saves over likes captures the current SNS reality well. It used to be ‘proof I was here.’ Now it’s ‘see this curated space through my taste.’ People are editing their account like a magazine page. Hiding the face removes the noise of who is in the photo and raises the purity of the place-and-vibe information. Calling that literacy rather than vanity feels right.”

Key themes in detail

🪞 Showing your face is the weird thing · 59.4% of engagement

The dominant move across both platforms is to flip the article’s framing on its head. Hiding your face on SNS isn’t strange. Posting your face is. The most-liked reply, with 2,362 likes, declared bluntly that anyone who isn’t a celebrity or a business posting their face publicly has ‘something wrong with their head.’ Several commenters generalized: this isn’t even a youth practice, plenty of people in their thirties, forties, and beyond do the same thing, because the obvious privacy logic doesn’t change with age.

One terse summary captured the whole thread: ‘It’s not a new normal. Showing your face was the abnormal thing. Period.’

🎓 You taught us this · 21.7% of engagement

The single most pointed reply, with 1,108 likes, addressed the press directly: ‘This is the result of you adults teaching us not to put our faces online. What is there to find strange?’ Other commenters described the same arc from the inside. They had grown up with school lessons, government PSAs, parental warnings, and the long Japanese internet tradition of pseudonymous BBS culture all converging on the same instruction: do not put your face on the public internet. Two decades later, those kids are adults, still following the instruction, and being asked by major news outlets to explain themselves.

‘If an adult criticizes me for it,’ one user wrote, ‘the only response I have is: weren’t you the one who taught me this?’

Underneath the irritation is a clear-eyed risk register. Reverse image search now lets anyone trace a face across the internet in seconds. Digital tattoo means anything posted lives forever. Most Japanese employers monitor their employees’ public social media, so for a salaryperson, a face-and-real-name post is a career-risk asset. Stalking, harassment, and the recent string of ‘baito-tero’ incidents where workers’ faces went viral after pranks at chain restaurants reinforced the lesson.

One Yahoo commenter framed it as a basic information security failure on the platforms’ part: even if a young user hides their face, the BeReal-style apps that capture surroundings will leak enough metadata for someone determined to identify them. A separate strand pointed at lookism: in a culture where appearance is judged ferociously, the safest move is simply not to enter the contest.

📰 The journalist should show her face first · 2.6% of engagement

A persistent, biting strain of replies challenged the journalist directly. ‘You wrote this article, why don’t YOU put your face online?’ one user demanded. Another searched the bylined writer’s name, found no public photo, and concluded: ‘The reason she hasn’t put her face online is the same reason no one else has either. The article is silly to write.’ Several readers argued that the act of writing about face-hiding as a curious phenomenon, while practicing the same behavior oneself, is the actual story.

Some commenters extended the critique to the framing of ‘literacy’ itself. The article gestured at whether the practice is ‘a passing youth fad or a new SNS-era literacy.’ One Yahoo commenter pushed back hard: ‘New? Internet literacy isn’t new. This has been the rule from the start.’

🔖 Likes vs saves: a real cultural shift · 2.3% of engagement

A smaller but more analytical thread, mostly on Yahoo News, took the article’s secondary point seriously: the shift from ‘likes’ to ‘saves’ as the metric young users care about. One commenter framed the change crisply. A ‘like’ is thin: someone scrolled past and tapped. A ‘save’ is thick: someone felt enough weight in the post to want it back later. SNS, this commenter argued, is no longer about ‘I am here, look at me.’ It’s about ‘look at this space I curated, edited like a magazine page’ — and removing the face is part of editing the noise out so the place, the object, the vibe come through clean.

A few commenters wrote similarly that the actual subject of most of these photos is the scenery or the food or the animal, and there was never a real reason for the user to be in the frame at all.
