# The warning text was in the file

2026-10-14

Arcadia says SpeeCAN RAIDEN, a disaster-mail vendor used by hundreds of municipalities, may have lost about 3.136 million emails, 105,000 phones, 15,000 fax numbers, contact names, and the stored message bodies. The cities are tenants. The file is the vendor’s.

Saitama mailed its list. The flood warning was on someone else’s disk.

Arcadia, in Minoh, said yesterday that SpeeCAN RAIDEN was reached. ITmedia, this morning, has the cities reading their own rooms. The vendor’s ceiling: about 3,136,000 email addresses, 105,000 phone numbers, 15,000 fax numbers, the contact name, and the text of messages kept in the delivery history. No cards. The company does not handle payment on this service. Some RAIDEN environments and Raiden School, the school-mail product, were stopped. ITmedia, citing Digital Agency material, puts about 700 municipalities on this vendor.

The timeline in Arcadia’s notice: 11 October, 16:30, odd behavior. About 03:00 on the 12th they blocked the path they could see and started scoping. On the 13th they named the path, stopped the rooms that were the door from 11:00, and published. Some cities say a card-company mail has already arrived at addresses from this list.

The tenants then counted. Saitama: 34,783 disaster-radio emails, 73 names and phones on a disaster phone service. Yokosuka: tens of thousands of disaster-mail addresses, plus fax and crime-prevention lists. Oita: 27,667. Okayama also put staff directory fields next to a few thousand resident addresses. Those numbers are rooms. They are not a second incident.

## What a city letter will be asked to mean

It will be briefed as “Saitama was breached.” Saitama’s radio-mail list sat on a vendor. Adding Yokosuka does not empty Oita, and it does not make Oita this room. The stored body is the part the other vendor notes did not have. A flood warning, a dam release, a staff callback, sitting next to the address it was sent to, is a script for the next call.

If your city mailed you, the fields they listed are the incident. If your city has not written, you are in the vendor’s ceiling until that letter arrives. Do not give a card number to a mail that already knows you get the disaster list. Arcadia asked administrators to tell registrants the same thing this morning: no name, no account, no password, no click.

The cities will keep issuing their own counts. Add them only after you have subtracted the overlap. The warning text does not issue a new copy each time a logo speaks.
