The company also revealed it is considering compensation payments for affected users, and that identification document numbers may have been among the leaked data. As a precaution, the site for its budget plan “ahamo” has also been taken offline. On 5ch, discussion centered on concerns that any compensation might amount to only a small number of points, questions about why the ahamo site was shut down despite no confirmed leak there, and the seriousness of the ID document data exposure.

I want 5 quadrillion yen, but it'll probably be like 500 points, huh… (riffing on the old '5000兆円欲しい!' meme)

Make it a free month instead

For a breach at a major corporation, ¥10,000 per person should be the bare minimum

Re: #44
Converted to d Points, that's about 100 points
65AnonymousNov 6, 2026 20:44
People still use Docomo? Why would you stick with a carrier that never changes? And what's even the point of holding d Points anyway? 😄

You can use them for regular shopping — and even for investing

Just spend them on a McDonald's mobile order

They work on Amazon too

Forget that — the real problem, like a thousand times over, is that the Earthquake Early Warning didn't go off on Docomo phones lmaoooooooooooooooooooooooooooo
88AnonymousNov 6, 2026 20:51
Re: #71
Now that you mention it, mine didn't go off either. With that fake earthquake alert last week or so, Docomo didn't push it out while other carriers did

Leaking ID document data is way too serious
86AnonymousNov 6, 2026 20:51
Re: #72
It's just the numbers on ID documents, so stuff like driver's license numbers or health insurance card numbers
74AnonymousNov 6, 2026 20:48
Before that, how about apologizing for selling personal data to Amazon?
85AnonymousNov 6, 2026 20:51
Re: #74
The one where the regulators came down on them. That's Docomo's third strike in a row
87AnonymousNov 6, 2026 20:51
I haven't gotten any notice at all — why's that?

Re: #87

On the 6th, affected individual users were sent an SMS with an apology, an outline of the incident, and precautions to prevent further harm

Not many stores take them. For online shopping, Yahoo Shopping is better anyway 🙄
119AnonymousNov 6, 2026 21:07
Re: #89
There's almost nowhere that doesn't take them — anywhere that accepts code payments takes them too
96AnonymousNov 6, 2026 20:54
Went to the ATM to withdraw from my Docomo Bank account, and the app just errors out and won't even open…

Re: #96
This is exactly why I don't want to use online-only banks

Re: #96
Isn't that just your Docomo line? There was a network outage
156AnonymousNov 6, 2026 21:36
Re: #96
Stop using your phone for ATM transactions. It's nothing but risk at this point

I'm on ahamo — do I get the compensation money?

It says right there that ahamo is separate

SoftBank would probably just stay quiet even if their data leaked

Wish a few more stores took Docomo Points. I've got a LIFE supermarket nearby so I'm fine, but it'd be nice if DAISO or Can★Do took them too
125AnonymousNov 6, 2026 21:13
Re: #114
Huh? You can use them — even at self-checkout and everything
117AnonymousNov 6, 2026 21:05
Just switched from ahamo to one of Docomo's plans for subscribers of a year or more. Hope my d Card info wasn't in the leak
149AnonymousNov 6, 2026 21:32
Re: #117
They said at the press conference that credit card info wasn't leaked
154AnonymousNov 6, 2026 21:35

Too many things are scary now, so I'm switching d Payment over to prepaid charge…

NTT seriously needs to quit with the remote work already

My Number national ID data is probably coming next. The Diet's in session right now, so they're probably timing the announcement to dodge that

Some image data's already leaked somewhere. There's been so many incidents I've lost track
164AnonymousNov 6, 2026 21:42
Re: #158
That's already leaked ages ago — some company outsourced the work to China without permission, remember

Background and Key Points of This Story

Since compensation payments aren’t legal damages but rather a gesture of apology from the company, actual payouts in past personal-data-leak cases have often stayed modest — so the comments predicting a small payout reflect reactions grounded in that precedent. Also, even though what leaked were the “numbers” on identification documents, driver’s license numbers and health insurance card numbers are used for identity verification by other services too; the risk is lower than if the document images themselves had leaked, but the numbers could still be used for impersonation. While ahamo has not been confirmed as affected this time, its site was taken offline as a precaution regardless, and the relationship between those two facts — along with the criteria behind the shutdown — was never made clear in the press briefing, so the “this explanation is contradictory” comments on the thread reflect reactions formed amid incomplete information.
