# Thirty-six hundred was the open network

2026-11-01

Japan’s Foreign Ministry says about 3,600 personal-information records on a network that talks to the outside may have left, including about 900 that belong to people who do not work there. Names and emails. The closed network, passports and travel advisories, it says, were not in it.

Three thousand six hundred is the network that was allowed to talk.

The Foreign Ministry said Friday — and it is still the letter — that it found unauthorized access on Wednesday and that about 3,600 records of personal information on a network connected to external systems may have left. About 900 of those, Nikkei’s reading, belong to people outside the ministry. Names and emails. Highly confidential material sits on a separate closed network. Unauthorized access there, it says, has not been confirmed. Passport systems and travel-advisory services were not in the path. Credentials on the reached side were invalidated.

This is not 260 million. That figure, from the commission’s year-to-date pile, is every Japanese notice added together. Do not paste the ministry into it.

## What 3,600 will be asked to cover

It will be briefed as every Japanese diplomat, and as every passport. Passports are the system they say was out. It will be briefed as the closed network. That is the network they say was not reached. A still-running travel advisory is evidence about that stack. It is not a finding that the 3,600 came back.

If you mailed the ministry from outside, you may be in the 900. A mail that already knows the desk and asks for a visa scan is not them.

Thirty-six hundred was the open network. Keep the closed one in a different sentence.
