The story

Citizen Watch announced on the 6th that unauthorized access to its website inquiry system may have exposed the personal information of roughly 100,000 people. The breach appears to have hit “Scala Communications,” the contractor Citizen outsourced its customer inquiries to, and payment information may also have been leaked. On 5ch’s Breaking News+ thread, posters speculated that Daiwa Securities used the same contractor, debated whether such breaches are a uniquely Japanese problem or a global trend, and reacted to the Digital Minister’s comment telling people to “protect your own information yourself.”

It's happening worldwide (we just only hear about it when it's a domestic company).

The contractor's security is a total sieve lol

Guess that's "AI power" for you (sarcastic jab at buzzwordy AI-security marketing).

Same contractor as Daiwa Securities? Other companies that outsource to them should check too.

Guess it's my fault for not protecting myself 😭

And the Japanese have the fax machine.

Doesn't this mean anything connected to the internet is basically doomed?

Paper, personal seals, and fax machines will save the world.

I bet next year some country's nuclear weapons system gets hacked and a missile comes flying in.
There's this sudden end-of-the-world vibe to everything lately.

But the media's still just covering ministers' scandals, and the Digital Agency is pushing the responsibility onto individuals.

It's over, man.

Re: #31
Japan doesn't even have nuclear weapons, so what exactly do you want the Digital Agency to do about it?

With credit cards, you're still okay as long as they weren't storing the security code properly.
But there have been cases in the past where a company stored it and it became a real problem when it leaked.

Credit cards are a lot safer if 3D Secure is enabled.
Also, as long as the user wasn't negligent, you get compensated.
49AnonymousOct 6, 2026 18:16
Wait, is this only targeting Japan, or is it happening all over the world?
That might actually help narrow down which country's behind the attacks lol

It's happening all over the world.

It's happening across the US, Europe, basically everywhere.

Denmark even made world news after a government leak that somehow exceeded its entire population.

Does anyone actually use Citizen watches? Seiko's the only real choice.

I'm from Nagano, so I'm partial to Citizen since they use movements made in Miyota (a town in Nagano known for watch-movement manufacturing).

> The company hit by the unauthorized access was 'Scala Communications,' which handles outsourced website inquiry services
Wouldn't other companies that outsource to them have been breached too?

Re: #57
Same inquiry contractor as Daiwa Securities.

I wonder if banks are actually okay.
Like that one megabank that's constantly having system outages.
Don't tell me we're entering an era where keeping cash under the mattress and paying with cash is the strongest move.

Re: #93
If even the banking systems get destroyed, that'd be a problem for the people running the show too — the whole economy would stop functioning.

It's not Mizuho, so I'm safe (´・ω・`) (a nod to Mizuho Bank's infamous history of repeated system failures).

I use a Q&Q. The movement's probably made by Citizen anyway.

If Toyota gets breached, Japan is completely finished.

Big win for this guy who never actually drives (a "paper driver" — someone who has a license but doesn't drive).

If Land Cruiser owners' info gets exposed, that could turn into a real mess.
Actually, there are already so many thefts it practically feels like it's already a mess.
Well, doesn't concern me — I've got two Suzuki kei cars.

Digital Minister! Hurry up and do something about this!!

The Digital Agency itself has had data leaks too, so…

"Protect it yourself," he says lol

"Protect your own information yourself" amid wave of unauthorized access incidents, says Digital Minister Furukawa

Scala Communications has 400 major listed companies as clients… doesn't that mean all of them got leaked too?

Background and Key Points of Discussion

The breach originated from unauthorized access to “Scala Communications,” the outside contractor Citizen outsourced its inquiry-handling to — Citizen’s own systems were not directly breached. Thread posters pointed out that Daiwa Securities also uses the same contractor, highlighting a “supply-chain” style damage pattern where breaching a single contractor can ripple out to affect multiple client companies. Another point of debate was whether this kind of unauthorized access is a problem unique to Japan or part of a global trend — citing cases in the US, Europe, and Denmark, the dominant opinion was that “it’s happening all over the world.” Posters also brought up Digital Minister Furukawa’s comment telling people to “protect your own information yourself,” expressing frustration with the government’s response. Readers should note that, at this stage, both the “roughly 100,000 people” figure and the possibility that “payment information was also leaked” remain unconfirmed possibilities — exactly what information was actually exposed had not been finalized as of the announcement.
