Why Japan’s PHP Community Is Booming – And Why You Should Know About It

This slide deck is for PHPers Day 2025 (15-minute talk)
site: https://phpers.day/

Description:
The PHP community in Japan isn’t just about technical events—it’s a place where engineers connect beyond company boundaries.In recent years, the Japanese PHP community has exploded in growth.
In 2023, four PHP conferences were held, increasing to eight in 2024, and in 2025, a total of ten conferences are scheduled to take place.
These conferences are not organized by a single entity but are independently hosted by dedicated volunteers in various regions across Japan.
Each community brings its unique perspective, showcasing the diverse appeal of PHP.
I have actively participated in numerous PHP conferences in Japan, both as a speaker and an organizer.In this session, I’ll talk about the PHP conferences and events happening in Japan and how engaging with the community has helped me grow professionally.
I also hope this talk helps you learn more about Japan’s vibrant PHP ecosystem.
