A magnitude 3.6 event is classified as a minor earthquake. Often felt by people indoors, especially on upper floors. Hanging objects may swing slightly; structural damage is extremely rare.
Felt only by a few persons at rest, especially on upper floors.

Your immediate response verifies shaking boundaries and helps ground-truth instrumental models.
Earthquake strength is measured on a logarithmic scale. Compare this event with the full seismic scale:
Because seismic scales are logarithmic, each whole integer increase represents:
Japan sits at the complex collision intersection of four major tectonic plates: the Pacific, Philippine Sea, Eurasian, and North American plates. Subduction of the Pacific Plate beneath the Japanese archipelago creates intense strain that releases as high-frequency megathrust earthquakes and volcanic activity along the Pacific Ring of Fire.
Originating at a depth of 60.0 km (Earth's Crust (0–70 km)), this rupture occurred occurred within the brittle upper crust. shallow earthquakes produce the highest peak ground acceleration and the sharpest surface shaking.
Seismologists note that minor aftershocks remain common in the 24 to 48 hours following tremors of magnitude 3.6. According to statistical seismic models, there is roughly a 5% probability of a subsequent event of equal or greater strength occurring in the same fault zone. Residents in Japan are advised to check living spaces for unsecured items.
