The story
Talent Wakatsuki Chinatsu reportedly said on the April 29 broadcast of TV Asahi’s “Wakatsuki Chinatsu’s Noisy Psychology Test” that people who don’t use smartphone cases have “zero risk management ability” and that it “makes her question their sanity.” The remark stemmed from a segment asking, “What’s the thing about men’s phone cases that makes you go ‘hmm’?” where “no case” was one of the options and became the flashpoint. In response, 5ch saw a wave of rebuttals grounded in personal experience — from people who’d gone over a decade without a scratch despite skipping a case, to those who said rugged or foldable phones simply don’t need one. The discussion also branched into case functionality, like heat dissipation and how handy flip-style cases are, so it never settled into a simple for-or-against debate.
Wakatsuki Chinatsu slams people who don’t use phone cases: “Zero risk management ability,” “Makes me question their sanity”
Talent Wakatsuki Chinatsu (42) appeared on TV Asahi’s “Wakatsuki Chinatsu’s Noisy Psychology Test” (airing Wednesdays at 2:20 a.m.) on the 29th, where she showed clear distaste for people who don’t use phone cases.
In the psychology test segment, viewers were asked, “Which type of men’s phone case makes you go ‘hmm’?” with four choices given: “brand-name,” “patterned,” “practical,” and “no case.”

What people said
My Android cost about 200,000 yen too, you know?
Android ranges from dirt cheap to crazy expensive
2chMate 0.8.10.241/samsung/SM-S938Q/16/GR
Android isn't exactly cheap either, is it
That's nice, not gonna lie
How come?
Having to flip it open every single time is a genuine waste of effort
I quit those — the faux leather on the flip cover breaks down over time and the hard-shell part starts peeling, gets nasty.
Better to just protect the screen with a film
Left a crack alone once and condensation got inside — phone died lol
Thanks to that, I'm a 5ch addict, but the phone's lasted 10 years
10 years…
So it's gotta be an Android, but seriously, what model?
Well, Wakatsuki Chinatsu has writers ranging from their teens to their 70s on staff, so…
Foldables are unbeatable
Wait, you're using a fold-type or flip-type phone?
Only hardcore gadget geeks buy those, right?
Going caseless or using a bumper is better for heat dissipation
Wish there were a feature where the back panel could pop open just when it's overheating
That's literally what the case is for
I've gone caseless with two phones for about 10 years without breaking either one, so I don't really get it
Do you have a weak grip or something? How are you even handling it?
I mean, as long as you're not constantly fumbling with it day to day, it's probably fine?
Everyone's situation is different anyway, so it's not like you can just lump all the no-case people together
I've also gone caseless for about 15 years and never broken one
Dropped it once, but got lucky and it came out unscathed
Honestly, a case is half just a good-luck charm anyway
Naturally, no case either
Because literally nothing ever comes in — no calls, nothing
Even I think that's a pretty empty life
I carry a phone too, and since I don't have friends, nobody but family ever calls me — but I still use a case
She probably just hates everything except her own way of doing it lol
Yeah, the camera bump sticks out
If you don't flatten it with a case, it wobbles when you set it down and the camera's prone to getting banged up
Phones just keep getting bigger anyway
Background and Key Points of This Topic
The remark Wakatsuki Chinatsu made on a psychology-test TV show, reported via Yahoo News, is the starting point for this thread — her blanket claim that “not using a phone case equals zero risk management.” On the thread, the caseless camp fired back with plenty of real-world counterpoints and functional arguments: “I’ve gone over 10 years without a scratch and no case,” “my phone’s rugged, so I don’t need one,” “cases hurt heat dissipation.” The pro-case camp, meanwhile, offered their own preferences, like “flip cases are handy on the train” and “Elecom’s ZEROSHOCK is unbeatable,” so it never boiled down to a simple yes-or-no fight. One thing readers might misread: Wakatsuki’s comment was just one opinion on a variety show, not something backed by any statistical data on actual breakage risk. Likewise, most of the thread’s counterarguments were personal anecdotes along the lines of “mine never broke” — neither side brought objective data to the table. In the end, against her strong claim about “risk management,” what piled up were grounded, practical responses shaped by differing habits, preferences, and use cases.
