2600 Meeting

The Tokyo chapter of the long-running 2600 meeting series gathers for its monthly evening session at beemars, a bar in Kabukicho, Shinjuku. The format is deliberately open: people show up, sit down, and talk about hacking, security research, or whatever else is on their mind. There is no agenda, no speaker list, and no registration ritual beyond turning up. 2600 meetings run worldwide on a common convention, and this is the only active one in Japan. The bar is reserved for the group for the whole two hours, so conversation can go wherever it goes without an audience of other patrons. Organizers point newcomers to a short video guide for finding the venue, which is on the third floor of a building that is easy to walk past. The crowd skews toward security practitioners, hobbyist hackers, and people curious about the field, and it runs on a monthly cadence, so dropping in once is a reasonable way to see whether it fits.
