Summary

The Tokyo chapter of 2600 holds its monthly meeting at beemars, a bar in Kabukicho, Shinjuku, from 19:00 to 21:00. The whole venue is reserved for the group, so attendees can talk openly. There is no agenda and no scheduled talks: people arrive, find a seat, and discuss hacking, security work, or whatever else comes up. 2600 meetings are a long-running open tradition in the worldwide hacker community, following a common set of rules (free to attend, open to anyone who shows up, held in a public space). This is the only active 2600 meeting in Japan, so it draws the security-curious from across the Tokyo area rather than from one company or campus. The listing links a short video guide to finding the venue, and background on the meeting format is available at 2600.com. Newcomers and regulars are treated the same way, and no introduction or preparation is expected.

About the community

2600 meetings are an open, long-running gathering format from the hacker community, held on a fixed monthly schedule in cities around the world under the same rules: free, open to anyone who turns up, and hosted in a public venue rather than an office. The Tokyo chapter is the only active one in Japan and draws people interested in hacking, security research, and adjacent technical curiosity. Sessions are informal bar conversations rather than presentations, so practitioners, hobbyists, and first-time attendees mix freely.
