Last week, we hosted our first ever GitHub Constellation event in Tokyo. 200 software enthusiasts joined us to hear talks from GitHub engineers, customers and partners. In case you missed it, here are some highlights!

We started with a keynote by GitHub’s Chief Business Officer, Julio Avalos, who was joined onstage by Japan Country Manager Jun Fujita. Julio reiterated GitHub’s commitment to the Japanese market, and revealed that there are over 180k people using GitHub daily in Japan. He also shared updates on recent product launches, and stated GitHub’s goal of making software development tools accessible to everyone. Later, Ryosuke Hasebe took the stage to share his experience using GitHub Enterprise at LINE.

Session highlights

Constellation attendees heard talks from business and technical leaders in two tracks. The technical sessions included a comprehensive discussion of how to think about OSS in enterprise software development by Hiroshi Nakamura (@nahi), Ruby committer and software developer at enterprise cloud services company Treasure Data. In his “DevOps for business” talk, Ryutaro Yoshiba, CTO of Attractor Inc., discussed how business people can get involved in DevOps efforts. His talk focused on DevOps as an effort to increase the efficiency of businesses to adapt to ever-changing environments.

Jun Fujita also led a discussion on stage with customers from Yahoo! Japan, CyberAgent and Fujitsu Labs to explore how they each approach software development. Much focus was on the cultural changes that organizations need to undertake in order to advance software dev practices and processes.

GitHub meetup


Before the main event, we opened our doors to the GitHub community by hosting a meetup at Super Deluxe, where speakers from XTREME DESIGN, KDDI, and Slack gave lightning talks before video artist Keijiro Takahashi took the stage to show off some of the open source visual art he makes using Unity and GitHub.

Thank you

Finally, thank you to our Japanese community, and to our sponsor, ClassMethod, for supporting Constellation—we’ll be back! If you plan to be in the US later this year, we’d love to see you again at GitHub Universe.
