What Japan Thinks: Why Do Reiwa-Era High School Girls Hide Their Faces in Every Photo?

A TBS report on the "face-hiding pose" trend among Japanese high school girls sparked two very different conversations. On Yahoo News, commenters traced the trend to COVID mask culture, Japan's beauty standards, and low self-esteem. On X, the most-liked reply was far blunter: "Because they're ugly and desperate for attention." The gap between the two platforms is the story.

Overall verdict: Two platforms, two entirely different conversations about the same trend. This topic produced a rare natural experiment in Japanese social media: the same story, discussed simultaneously on X and Yahoo News Japan, with starkly different results. On X, the most-liked comment (376 hearts) was a single cruel sentence: “Because they’re ugly and desperate for attention.” The replies that followed were largely variations on this theme, treating the face-hiding pose as evidence of insecurity, vanity, or both. On Yahoo News, the top comments told a completely different story. The most-agreed comment (959 agrees) was a gentle observation from someone who had just seen the trend in action on TV and connected it to post-COVID mask culture. The second most-agreed (542) offered a thoughtful analysis of how masks during COVID let people present only their eyes, making many people realize they looked more attractive with the lower face hidden. The Yahoo commenters treated the trend as a cultural phenomenon worth understanding; the X commenters treated it as a character flaw worth mocking.
Note: Comments on X (formerly Twitter) in Japan tend to skew toward the political right, though individual threads may lean left depending on the original poster and topic. These comments are not necessarily representative of the Japanese population as a whole.

What the tweet was about

On April 15, 2026, TBS News reported on a trend among Japanese high school girls: the “face-hiding pose” (顔を隠すポーズ), where students cover the lower half of their face with their phone, hand, or other objects when taking photos. According to a Shibuya Trend Research survey, the pose ranked #1 among trending high school poses for spring 2026, ahead of “smartphone hiding” (スマホ隠し) and the traditional peace sign.

The trend did not emerge in a vacuum. Japan’s three years of near-universal mask-wearing during COVID created a generation of teenagers who spent their formative social years with the lower half of their face hidden. The “mask beauty” (マスク美人) phenomenon, where people appeared more attractive with a mask on because only the eyes were visible, became a widely discussed social observation. As mask mandates lifted, many young people, particularly young women, found themselves uncomfortable showing their full face, having grown accustomed to the filtered version.

Japan’s beauty standards place heavy emphasis on facial proportions, particularly the concept of “kogao” (小顔, small face). Several commenters noted that hiding the lower face creates an optical illusion of a smaller face while also concealing features that are harder to alter with makeup, like the jaw, chin, and mouth shape, unlike eyes, which can be dramatically transformed with cosmetics and tape.

The most-agreed Yahoo News comment was a warm, curious observation about the trend. The most-liked X comment was a one-line insult. The contrast illustrates a persistent pattern in Japanese social media: Yahoo News comments skew older, more analytical, and more empathetic; X comments skew younger, harsher, and more performative. Neither platform is “right,” but reading both gives a fuller picture.

COVID mask culture legacy
[Yahoo] 昨日の夜テレ東の番組を見ていたら女子高生たちがインタビューされていたが、かなりの女子高生たちがスマホで顔の下半分を隠して話していたので、何で隠すんだろうと思ったら流行ってるんですね。コロナ禍を経験してマスクで顔を隠すことに慣れているのもある気がしますが、将来画像を見返した時にこんなポーズ流行ってたな、なんて懐かしく思うんでしょうね。 若い時は好きなことをやったらいいと思います、楽しいですよね。
“[Yahoo] I was watching a TV Tokyo show last night and a lot of the high school girls being interviewed were holding their phones over the lower half of their faces. I wondered why they were hiding, and it turns out it’s a trend. I think being used to hiding behind masks during COVID is part of it. They’ll probably look back at these photos someday and feel nostalgic. When you’re young, just do what you enjoy.”

COVID mask culture legacy
[Yahoo] おそらくこれは、コロナ禍のころにマスク美人というのが流行ったからだろうと思う。 基本的に顔のパーツのバランスがいいと美人に見えるものではあるけど、マスクで口を隠すことで目の部分だけを見せて、バランスの悪さを誤魔化して美人に見せることが出来ることに気付いた人が多かった。 それでコロナ禍のあとは、マスクじゃなくてスマホや手で口を隠すことで、マスク美人と同じ効果を生み出そうということから始まったのではと思う。
“[Yahoo] This probably started because ‘mask beauty’ became a thing during COVID. Basically, covering your mouth with a mask lets you show only the area around your eyes, hiding asymmetry in the lower face and making many people realize they looked better that way. After COVID, the face-hiding pose recreates the same effect with a phone instead of a mask.”

Japanese cultural trait
[Yahoo] 顔を隠したがるのは日本人特有なものかもしれない。例えば自分の顔に点数をつけるとしたら何点か自己採点をしたら、おそらくみんな低くつけるでしょう。本当は高いのに自分で高得点をつければ勘違いだのなんだと言われるから低くく言っておけばセーフティーなんだよ。 たぶん外国人に同じ質問をしたらみんな自分に高得点をつけると思うんだ。 SNSを見ても日本人はスタンプ等つけて顔を隠しがちだが外国人でそれは見たことがなく堂々としている。流行りどうこうでなくお国柄かと思う。
“[Yahoo] The desire to hide your face might be uniquely Japanese. If you asked people to rate their own face out of 10, most Japanese people would score themselves low. Even if they’re actually attractive, they’d rate low because scoring yourself high feels arrogant. That’s a safety-first mentality.”

@YahooNewsTopics 女学生が顔を隠すのは、恥じらいではない。見せるべき自分と守るべき自分の境界を、一瞬だけ自らの手で統べようとする儀式だ。あの仕草は防御ではなく、若さという光を自分で制御しようとする小さな美学なのだ。
“[X] When a girl hides her face, it’s not shyness. It’s a ritual of drawing the line between the self she shows and the self she protects. It’s not defense; it’s a small act of aesthetics, controlling the light of youth with her own hand.”

[Yahoo] 美人の条件に口元って重要だけど口元が綺麗であるハードルが高いんだよね。 それに追加すると顎とか輪郭もね。 目元はアイプチだとかなんだで形を変えて作り込めるけど、口元は形を変えられない。 目元だけなら美人に映るんだよね。 言い換えると口元や顎まで写すと残念な人が増える。
“[Yahoo] The mouth is crucial for looking attractive, but the bar for having a beautiful mouth is really high. Eyes can be faked with tape and makeup, but the mouth can’t be reshaped. So if you only show the eyes, more people can pass as attractive.”

Key themes in detail
😷 COVID mask culture legacy (47.4% of engagement)

The single most common explanation across both platforms: three years of mask-wearing during COVID fundamentally changed how young Japanese people relate to their own faces. Multiple commenters, particularly on Yahoo News, described the “mask beauty” phenomenon: with only the eyes visible, facial symmetry appeared better, imperfections were hidden, and many people received more compliments on their appearance than before. When masks came off, the full face felt like a downgrade. The face-hiding pose, commenters argued, is a post-pandemic coping mechanism that recreates the mask effect without actually wearing a mask. One Yahoo commenter (542 agrees) explained the mechanics precisely: masks let people show only their best feature (eyes) while hiding the hardest to modify (mouth, jaw, chin).

😔 Low self-esteem / appearance anxiety (31.9% of engagement)

A significant cluster framed the trend as a symptom of deeper anxiety. Yahoo commenters analyzed Japan’s tendency toward low self-evaluation: if you asked Japanese people to score their own face, most would rate themselves lower than they deserve. The face-hiding pose, in this reading, is not vanity but the opposite: a fear of being seen and judged negatively. One commenter called it “safety-first behavior,” where hiding the face is a way to participate in photo culture without fully exposing yourself to criticism. On X, this same observation was made but with contempt rather than empathy: “They hide because they know they’re ugly” was the blunt version of the same insight.

✨ Beauty standards / facial features (3.4% of engagement)

A practical-minded group discussed the specific facial anatomy at play. Eyes can be dramatically altered with makeup, double-eyelid tape, and circle lenses. The mouth, jaw, and nose cannot. The face-hiding pose strategically hides the features that are hardest to change while showcasing the features that are most easily enhanced. One Yahoo commenter (101 agrees) broke it down: “Eyes are the one feature you can convincingly fake. Everything below the nose exposes the real you.” This framing treats the pose less as a psychological phenomenon and more as a rational response to the tools available.

📱 Filter culture / photo editing (4.6% of engagement)

Several commenters connected the face-hiding pose to the broader ecosystem of photo editing and filters. The rise of BeReal, which prohibits edited photos, was cited as an accelerant: if you can’t filter your face, the next best option is to physically hide it. Others pointed to Japan’s long history of purikura (photo booth) culture, where editing and decoration of photos has been normalized for decades. The face-hiding pose is, in this view, the latest adaptation in a decades-long negotiation between Japanese youth and their own images.

🔄 Nothing new / generational cycle (1.0% of engagement)

Multiple commenters, particularly women in their 30s and 40s, pushed back on the idea that this is a new trend. “I’m in my late thirties and we did exactly this 20 years ago,” one Yahoo commenter wrote (99 agrees). “We’d wear oversized cardigans and cover our mouths with the sleeves in purikura, or scribble over our noses and mouths during editing.” This camp argued that every generation of Japanese teenage girls has found ways to partially hide their faces in photos, and that the current version is simply an update of the same impulse using smartphones instead of sticker machines.

🇯🇵 Japanese cultural trait (4.5% of engagement)

A smaller but interesting thread treated face-hiding as distinctly Japanese. One Yahoo commenter (464 agrees) argued that the desire to hide one’s face reflects Japan’s culture of modesty and low self-assessment: foreigners would score themselves higher on a self-evaluation and would be less likely to hide. Another commenter traced it back to historical practices of noblewomen hiding their faces behind fans and screens. A more playful response on X simply wrote: “We’re descendants of ninjas, after all.”

🙄 Narcissism / attention-seeking critique (0.3% of engagement)

The harshest reactions came almost exclusively from X. The most-liked reply (376 hearts) dismissed the trend as ugly girls seeking attention. Others accused the subjects of performative modesty: hiding the face while posting the photo is inherently contradictory, they argued. If you genuinely didn’t want to be seen, you wouldn’t post at all. This camp treated the face-hiding pose as a calculated social media strategy rather than genuine insecurity, and judged it harshly. This perspective was almost entirely absent from Yahoo News, highlighting the platform’s different user demographics and norms.


What Japan Thinks: Fukuoka Swaps School Milk for Green Tea and Japan Has Feelings

Fukuoka City announced it would replace school lunch milk with green tea once a month, citing a better pairing with Japanese cuisine like grilled saba. The internet responded with 302 replies and a surprisingly passionate debate: is school milk about nutrition or about taste? The most-liked comment (3,356 hearts) captured the paradox perfectly: “When you think about it, milk doesn’t go with Japanese food at all. But as a kid, I never once cared.”

When police announced that an 11-year-old boy missing since March was found dead in a Kyoto forest with cause of death listed as “unknown,” Japanese social media split into two camps: those piecing together a timeline that points suspicion at the stepfather, and a furious counter-movement demanding that amateur sleuths stop speculating about a child’s death. The most-liked comment (1,246 hearts) told would-be detectives to shut up.
