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

This event started in 2017 . From 2020, the disorganizer will change from Sebastian & Stephen who are great Java Champions to JJUG (Japan Java User Group).

JOnsen 2020 dates are set.  Please reserve May 29th through May 31th.  The venue is Aomoriya in the northernmost of mainland Japan. 

The registration page will open shortly! The link will be here, so please wait a moment 🙂
