Well, I am not so sure I like doing this post, but ignoring it and not doing it would be almost impolite, it would seem. I don't suppose most would be aware of how very unusual this shake is, but it is unusual. And, again, it's the depth and that makes me feel even more uncomfortable. Depth was a key point of an earlier 'shake' post I did.
Anyway:
Earthquake Information (Earthquake and Seismic Intensity Information)
Issued at: 14:28 JST 29 Apr 2019
Occurred at: 14:24 JST 29 Apr 2019
Latitude: 34.6N
Longitude: 137.5E
Depth: 320km
Magnitude: 4.1
Region Name: Enshu-nada
As this is a recent event there is no (dot)htm tag on that address on the JMA site, but as soon as there is a new shake an htm tag will be needed.
So I just spotted this a short time ago, obviously, so all I know is that a shake in that region at that depth is super unusual. How 'super' is super, I do not know yet. That could be hard to dig up, no pun intended. .... (Well, no pun intended originally.)
