This occurred yesterday evening (july 26 going into july 27 JST)..
This video above, is a follow up eruption from the main caldera this time — truly impressive to see at night… a very long lasting eruption of lava…complete with large volumes of ash, several large static discharge lightning events, and even several flashes of what appears to be some kind of plasma …
The day before.. on July 25, 2012 — we saw the back side of the mountain erupt a VERY sizable plume, and send off massive shockwaves visible for many thousands of feet. It had been several years since the last time the back side of sakurajima showed noticeable activity.
