Earthquake in the morning in Tokyo

My first earthquake in Tokyo. Woke up at about 2am on Saturday morning by a little shake. Nothing compared to the one I experienced in Taipei a couple of years back, but this one was still a first. Nothing like a first! Here’s a copy and paste of the details from the USGS website.
