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.
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?
Often felt by people at rest close to the epicentre, rarely causes damage.
It released roughly the energy of 5.4 t 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 140 km this was a intermediate-depth earthquake, which spreads shaking over a wider area but less intensely.
M3.7 releases about 32× the energy of M2.7, and its waves are about 10× taller on a seismogram. Energy: 5.4 t of TNT vs 169 kg of TNT.
Each square is the energy of one M2.7. Energy from log₁₀E = 1.5M + 4.8.
Aftershocks and nearby activity
No later earthquakes have been recorded within 30 km so far. Aftershock rates usually fall off roughly in proportion to 1/time.
