It was a Shindo 4 by me (on the Japanese 1-7 earthquake scale). Shindo 5 at the epicenter in northern Saitama. Magnitude 5.6.

The iPhone helpfully said “Earthquake. Earthquake. Earthquake” in Japanese. Like, “duh.”

Some things fell over, but it passed quickly. I thought my monitors might fall over but they didn’t.

All over for now.
