JJUG CCC 2025 Spring

Saturday, June 7, 2025 - 07:00 by Ivar Grimstad

I’m back in Tokyo again. This time for JJUG CCC 2025 Spring. This Cross Community Conference (CCC) is organised in twice a year and attracts around 1000 attendees every time. I was a speaker at the Fall edition last November, and now again on the Spring edition. Most of the speakers are local, but there are a few coming from other parts for the World. I had the pleasure of catching up with Steve, Cassandra, and Josh.

I presented The Evolution of Enterprise Java with Jakarta EE 11 and Beyond, which takes us through the history of Enterprise Java from the Past, via the Present, and to the Future.

Tokyo is such a great city to visit. It is extremely well organised and everybody is super-friendly. I didn’t try it, but I am pretty sure you can forget your mobile phone on a bench at a subway station in the morning, and be able to pick it up again in the afternoon. Of course, I wouldn’t recommend anyone trying it, but if you were to, Tokyo would be the place to go.
