Is there something noteworthy about this specific incident? Faults of this magnitude are unfortunately relatively common. For example earlier this month there was a 6.2 quake not far from this one on the coast of the other side of Japan. I don't expect major damage or deaths, hopefully.
AFAICT the JMA press release[^1] says this is just "Sagami Trough"[2] subduction, nothing out of the ordinary. It also mentions that between the two most-recent M8+ quakes (1703 and 1923), the recurrence time for ~M7 events was about 27 years.
Assuming no major aftershocks closer to the cities then hopefully it is a non-event. It was enough to trigger all of their audible alerts for the impending quake and enough for USGS to send me alerts.
The news piece you linked seems to be about a Yakuza shooting in Machida, not about an earthquake?
Here in the west side of centeral Tokyo, the quake was long and definitely noticeable, but nothing out of ordinary. In Narita Airport, I hear it shaked pretty hard.
