The epicenter of the 2011 Japan earthquake, also known as the Great East Japan Earthquake, was located off the northeastern coast of Honshu, Japan, near the city of Sendai in Miyagi Prefecture. The earthquake struck on March 11, 2011, with a magnitude of 9.0, making it one of the most powerful earthquakes ever recorded. Its epicenter was approximately 70 kilometers (43 miles) east of Sendai, at a depth of about 30 kilometers (19 miles). The quake triggered devastating tsunamis that caused widespread destruction and led to the Fukushima Daiichi nuclear disaster.
The point is the epicentre of the earthquake.
The earthquake in Japan lasted about 3-5 minutes.

The earthquake that hit Japan in 2011 is commonly known as the Great East Japan Earthquake, or the Tohoku earthquake and tsunami. It occurred on March 11, 2011, and had a magnitude of 9.0, triggering a devastating tsunami.
There were over 16,000 deaths in Japan's major 2011 earthquake.

The epicenter for the magnitude 9.0 earthquake (originally recorded as 8.9) in Japan on March 11, 2011 was reported by U.S. Geological Survey (USGS) and others to be 129 kilometers (80 miles) off the east coast of the Oshika Peninsula, Tōhoku, near Sendai at a depth of 32 kilometers (20 miles). This earthquake triggered the massive tsunami that followed shortly after.
The epicentre of an earthquake is the point on the earth's surface away from which the seismic waves produced by an earthquake radiate. This is similar to the way waves or ripples in a pond move outwards in concentric circles from the point where you throw a stone into the water. As such the epicentre is the point on the earth's surface directly above the earthquake's focus or hypocentre (the point within the earth where the fault rupture or movement actually occurs).
The difference between the epicentre and the focus of earthquakes is this:The focus of the earthquake is where the actual earthquake occurred and the epicentre is on the ground directly above the focus. The epicentre is used to say where the earthquake was in relation to places near where it occurred.Hope this helped :)
