PHP Conference Japan 2026

Overview

The annual gathering of Japan's PHP community and one of the country's oldest language conferences, first held in 2000. Run by a volunteer committee tied to the Japan PHP Users Group at Ota Industrial Plaza PiO, its home since the first edition. Despite free admission, it packs around 30 accepted talks across multiple tracks, ranging from AI-era development and legacy code to PHP internals such as OPcache and JIT, making it a fixed point for observing where Japan's PHP community stands.

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.
