Summary
The Tokyo chapter of the 2600 hacker meetings gathers for its monthly session, an open evening for talking about hacking, security research, and whatever else comes up. 2600 meetings are an informal worldwide tradition tied to the hacker quarterly of the same name, and this is the only active one in Japan. The group takes over the whole bar in Kabukicho for the two hours, so the room is private and conversation runs freely. There is no fixed agenda or speaker list: people show up, find a table, and talk. Anyone curious about security, reverse engineering, or the surrounding culture is welcome regardless of experience level. The organizers link a short video guide to finding the venue, which is worth a look before heading over since the bar sits on an upper floor of a Shinjuku building.
