Tokyo, Japan plays host to Open Source Japan 2026, the Open Source Summit Japan, from 7 December 2026 to 9 December 2026, welcoming the sector for another closely watched edition. It connects specialists, practitioners and industry leaders, and has grown into a key date on the sector's calendar. Because it comes around every year, each edition arrives with genuine anticipation. The Linux Foundation produces the event, drawing on years of practice to keep each edition sharp.

Few cities suit an event like this as well as Tokyo. As a destination, Tokyo combines accessibility, hospitality and a character all its own. Whether you fly in or come by rail, Tokyo is well served and easy to move around. You will find plenty of places to stay within easy reach of the venue, whether you prefer convenience or character. Factor in some downtime, because Tokyo is the kind of city that turns a work trip into something more. Few places in Japan are as well suited to hosting the international crowd this event attracts as Tokyo.

From fundamentals to the cutting edge, Open Source, Software Development, Software and Coding run through every part of the programme. Expect a packed line-up of panels, fireside chats and interactive sessions. Coffee breaks, lunches and socials are as much a part of the value as the sessions themselves.

It is as much about the conversations in the hallways as the sessions on stage. Open Source Japan 2026 remains a key fixture for decision-makers, specialists and curious newcomers alike, and an edition worth marking on the calendar.
