In was reported that the earthquake off Japan was followed by a series of intense aftershocks. The largest earthquake at the time had a magnitude of 9.0 (earlier reported as 8.9) and caused the 23-foot (or 7 meter) tsunami.
- Following those events were 200+ earthquakes on March 11 alone with magnitudes between 3.9 and 7.9 according to USGS data
- Of these aftershocks, over 24 were larger than the earthquake that devastated New Zealand on Feb 22nd (2011) which was the country's worst natural disaster since 1931
- Early on Saturday, March 12, an additional magnitude 6.2 earthquake hit Japan at its central region on the west coast of Honshu.
- On Tuesday, March 15 there was a magnitude 6.2 earthquake in central Japan immediately near Mt. Fuji, which is an active volcano.

We live in Northern Japan, and we have been tracking them on the USGS site. It only tracks 4.5 or greater for Japan. As of 9:30 pm local time on the 24th of March, here is our "quake count"
811 earthquakes in Japan, starting the count with the 7.3 on March 9th, 2011. (many of them have been determined to be "preshocks")
803 of them have been off the Eastern coast of Honshu, in the region of "the big one".
401 have been 5.0 or greater
47 have been 6.0 or greater

How many earthquakes have japan had over the years?
Because the island of Japan lies in an area where several plates meet, it has experienced frequent earthquakes. Earthquakes are caused by the release of energy or seismic waves when these plates move. See the related links below for a list of earthquakes that have hit Japan in the past. The most recent earthquake and biggest to ever hit Japan occured March 11, 2011 and measured 8.9 on the Richter scale.

On March 11 alone, there were 200+ aftershocks. From the 9.0 magnitude earthquake on Friday March 11 05:46:23 UTC until March 31 midnight there were approximately 2,806 earthquakes ranging in magnitude 3.9 through 7.9. Second, the large 9.0 earthquake triggered the massive tsunami that devastated large parts of the Japan coast.

No. It is only one of many times that an earthquake and tsunami have hit Japan. Earthquakes in subduction zones such as the one of the coast of Japan often trigger tsunamis. The March 2011 earthquake, at magnitude 9.0, was the strongest on record in Japan though.
What part of Japan is often hit by earthquakes?
