Sometimes unusual ideas are the best. What about holding a Java unconference at a relaxing hot spring (Onsen) deep in the heart of Japan? Having Java experts from Japan and all around the world together in a relaxing atmosphere to philosophize and exchange ideas. Held this year for the very first time.

JOnsen 2019 dates are set.  Please reserve May 24th through May 26th.  The venue will be on the Kyushu Peninsula in the southernmost part of mainland Japan.  This is easily reachable by train from Tokyo or you can fly in or out of Fukuoka airport.  The exact Onsen hotel is not yet determined, but we are working on this.  🙂
