Shaking is an estimate from the intensity prediction equation of Allen, Wald & Worden (2012), not an observation. Local ground and buildings can change it by a level or more. Likely felt out to about 11 km.
Every agency's solution
Agencies locate earthquakes with their own stations and methods, so their numbers differ. We match reports of the same event by time, distance and magnitude and show them side by side. The headline uses JMA.

How big was it?
Usually not felt. Recorded by nearby seismometers; thousands occur worldwide every day.
It released roughly the energy of 120 kg of TNT. Magnitude is logarithmic: each whole step means about 32 times more energy and 10 times larger waves on a seismogram. Depth matters too: at 0 km this was a shallow earthquake, which is felt more strongly at the surface than a deeper one of the same size.
M2.6 releases about 32× the energy of M1.6, and its waves are about 10× taller on a seismogram. Energy: 120 kg of TNT vs 4 kg of TNT.
Each square is the energy of one M1.6. Energy from log₁₀E = 1.5M + 4.8.
Aftershocks and nearby activity
14 later earthquakes within 30 km; the largest was M3.1 8 days ago. 5 in the 7 days before. Aftershock rates usually fall off roughly in proportion to 1/time.
Mainshock M2.6
14 later earthquakes nearby. Aftershock rates typically fall off roughly as 1/time (Omori's law).
