OSPN（Open Source People Network）日本
OSPN (Open Source People Network) Japan has organized the Open Source Conference (OSC)—a nationwide gathering of open source enthusiasts—since 2004. The event takes place in Tokyo, Osaka, Kyoto, Hokkaido, Fukuoka, and other local cities across Japan, bringing together a wide range of open source contributors and enthusiasts who are deeply rooted in their local communities.
As it did last year, the booth at the FOSS for All Conference 2026 will introduce the Open Source Conference and Japan's open source culture, and showcase a variety of IT Dōjinshi (同人誌) books—self-published technical books that are an important part of Japanese subculture connected to the community. Many of these books were donated by authors Masafumi met at Comic Market in Japan, along with contributions from GishoHaku (技書博), a Japanese IT Dōjinshi community.
Masafumi leads the Raspberry Pi community in Japan and helps businesses adopt Raspberry Pi, especially across Asia. He has also moderated the OSPN Japan track at COSCUP since 2019.
He is currently starting a new venture with sake and wine breweries, using IT to introduce Japan's brewing culture to overseas visitors so that they can discover something new during their stay in Japan.
Masafumi has exhibited at COSCUP and FOSSASIA every year, introducing Japanese IT culture and helping local open source communities and Japanese open source communities get to know each other and make friends across borders.
