On the Japanese scale registers 3 (out of 7).
ADDing in – a M4.3 quake also reported just north, in Tochigi Prefecture
The helpful people on Twitter and other social media inform me after posts like this that anything under 6 in Japan is not of much concern. I, on the other hand, am hiding under my desk just thinking about any quake. Japanese people are obviously made of sterner stuff. 😀
