First held on July 22, 2000 in the small exhibition hall of Ota Industrial Plaza, making it among the oldest language-community conferences in Japan. It grew to fill the entire venue, and for a quarter century has been passed down between volunteer committees in the users group's leaderless tradition.

Voices

Fitting for the milestone 25th edition in PHP's 30th anniversary year, the venue buzzed around the theme of PHP's present and future (from every Tech Blog's report, in Japanese)
Seven engineers from a single sponsor company took the stage, framing it as both community give-back and learning ground (from Codmon Product Team Blog, in Japanese)
