If you're looking at the USGS map, yes. USGS will typically only show 4.0M+ outside of the USA.
There have been quite literally hundreds from Taiwan all up through the entirety of Japan if you include quakes under 2.0M
You're correct, that that many 4.0M+ clustered in one location, in high frequency, is not normal. Due to Japan being on a major subduction zone, and there being undersea volcanoes basically directly under where the clusters are happening, this swarm could be foreshocks to something larger.
