“Maybe he’s lacking common sense” — Influencer with 3 million total followers Kai Haruki sparks controversy after restaurant refuses to mix him a Calpis Soda

The story

Influencer Kai Haruki (38), who commands a total of 3 million followers, has stirred controversy by sharing his opinion about an experience at a restaurant where he was refused a Calpis Soda — staff told him the menu only had Calpis Water and soda water, and that they couldn’t mix the two for him. Following an article published on September 22, discussion on 5ch (Geinou/Sports News+) spread from comments like “maybe he’s lacking common sense,” to rebuttals grounded in the practical realities restaurants face — such as whether they even stock the concentrate and how commercial drink dispensers work — and even extended into discussion of his educational background.

Order two and mix them yourself, idiot.

He's just not smart enough to think of that.

Re: #2
Exactly, lol.
Figure out "how can I make this work?" yourself.
190AnonymousSep 22, 2026 15:00
Re: #2
Seriously, can he not do that himself?

This influencer is the real idiot here, lol.
4AnonymousSep 22, 2026 14:19
Someone whose upbringing shows through this clearly has 3 million followers…
This country's standards are truly finished.

Re: #4
It says "total," idiot.
On X alone he's only got like 200k.
48AnonymousSep 22, 2026 14:30
Re: #4
Probably bought followers.
Boost the count some,
and gullible followers who fall for it pile on — that's the scheme.
17AnonymousSep 22, 2026 14:22
You need the concentrate for that, right?
Diluting Calpis Water with soda water doesn't make Calpis Soda.
36AnonymousSep 22, 2026 14:28
Re: #17
That just makes a watery Calpis Soda.
You don't even need to think about it to know that.

People with about this level of education tend to get a chip on their shoulder —
especially if they rose up partway through and started feeling invincible.

On the flip side, some kids get pegged in middle school as shoo-ins for Todai, Kyoto U, Hitotsubashi, or Osaka U,
then fall short later — some of those end up like this too, while others become overly self-conscious instead.

Among private universities, it's the type who'd say "I took the old Showa-era Chuo University Law Faculty exam —
not the Political Science Department with its different test date, but the Legal Studies Department, the day before!"
Of course he passed both, and he'll never let you forget that part either.

He dropped out, so he can say whatever he wants about it.
42AnonymousSep 22, 2026 14:30
Re: #33
It'd be the same even if the restaurant did it, idiot, lol.
57AnonymousSep 22, 2026 14:33
Re: #42
Whoa, an idiot.
Calpis Soda is Calpis concentrate cut with soda water.
68AnonymousSep 22, 2026 14:35
Re: #57
I think you're the idiot.
Even if the restaurant did it, all they could do is mix it.
74AnonymousSep 22, 2026 14:37
Re: #57
The restaurant doesn't have the concentrate, though.
62AnonymousSep 22, 2026 14:33
Calpis Soda actually existed before Calpis Water, you know.
75AnonymousSep 22, 2026 14:37
Re: #62
Same as tea — back then nobody thought bottled Calpis Water would even sell.
It was the era of "if you want tea, brew it yourself; if you want Calpis Water, just mix Calpis with water yourself."
77AnonymousSep 22, 2026 14:38
Re: #68
Calpis Water isn't the same as Calpis concentrate, you know?
98AnonymousSep 22, 2026 14:42
Re: #1
For guys like this, best to just hand him Calpis concentrate on the rocks (lol)
127AnonymousSep 22, 2026 14:48
Re: #98
To begin with, plenty of restaurants don't even stock Calpis concentrate.
A lot of izakayas these days make soft drinks with commercial dispensers (like the ones at drink bars),
so you just press the Calpis Water button and it comes out — the concentrate itself often isn't available separately.
107AnonymousSep 22, 2026 14:43
Let's go pull the same stunt at this guy's own place of business!
116AnonymousSep 22, 2026 14:45
Re: #107
Yeah, let's go order a Calpis Soda at his cosmetic clinic.
I'm sure they'll figure out "how can we make this work?" for us.
111AnonymousSep 22, 2026 14:44
If you just slap down like 100,000 yen on the counter, I bet they'd do it.
You're not being positive enough, buddy.

😂😂😂

"You've got beer and ginger ale, so why can't you make a Shandy Gaff? lol
Do you even know what a Shandy Gaff is? lol
It's made by mixing beer and ginger ale, did you know that? lol
Get it?? lolol"


Ran into a customer like that back when I had a part-time job.
130AnonymousSep 22, 2026 14:48
Re: #120
People like that actually exist, huh, lol.
Man, I want to punch him!
146AnonymousSep 22, 2026 14:51
Re: #120
Yeah, they exist.
The type who only acts tough at people who won't ever push back, just to blow off steam.
And even if it were possible, there's still the issue of how to price it.
133AnonymousSep 22, 2026 14:49
They've got beer.
They've got tomato juice too.
No Red Eye [a beer-and-tomato-juice cocktail] on the menu.

"Can I get a Red Eye then, lol"

Is even that not allowed?
157AnonymousSep 22, 2026 14:52
Re: #133
Depends how much you're willing to pay.
If you pay for a full beer plus a full tomato juice, some places might do it for you.
166AnonymousSep 22, 2026 14:54
Re: #133
An independent place might do it.
A chain definitely won't.
181AnonymousSep 22, 2026 14:59
Re: #133
Say you mix them 1:1.
That leaves a 0.5-unit discrepancy in each.
That means neither drink was poured in its correct measured amount,
and inventory discrepancies count against the store's performance review.
That's why chains absolutely won't do it.
142AnonymousSep 22, 2026 14:50
Re: #88
"Calpis Water is on the menu.
Soda water for splits is on the menu too."

Mixing those would just water down the Calpis, though.
Also, I don't think it's cool to dodge by calling people "autistic"
just because you can't counter their argument.
154AnonymousSep 22, 2026 14:52
Re: #142
It's watered down — that's exactly why they won't serve it…
That's the whole point of "if you want it, make it yourself."
Your reading comprehension is seriously lacking.

He dropped out, so that proves nothing.
Just a high school graduate.
170AnonymousSep 22, 2026 14:56
Just mix Calpis and soda water yourself to make a Calpis-Soda knockoff.
Is this influencer's brain just fried or something?

Re: #170
Does that restaurant even serve plain soda water on its own, I wonder?

Background and Key Points of the Debate

Calpis Soda is made by cutting Calpis concentrate with soda water — a different product, made by a different process, from ready-to-drink Calpis Water. As pointed out in the thread, many restaurants serve pre-made Calpis Water straight from commercial dispensers, and plenty of establishments don’t handle the concentrate separately at all. There’s also a practical business reason chains in particular tend to refuse such requests: mixing up a drink that’s not on the menu creates a mismatch between recorded pour amounts (inventory tracking) and actual stock on hand. On 5ch, opinions split between rebuttals grounded in these restaurant-side constraints and calls for “common sense” befitting someone with his reach. As for his educational background, while he’s noted as having gone on to Kobe University’s Faculty of Business Administration, commenters in the thread also pointed out that he dropped out — details that can’t be confirmed from the original article alone.
