Volcanic islands tend to owe their existence to the volcano. The same force that burns and buries the life that settles on them is the same force that created land to rise out of the sea in the first place. Without volcanic activity to continually add land to the islands, eventually erosion and other influences will wear the islands down to submerge them entirely under the sea.
In the case of Hawaii, for instance, a fixed point in the mantle below the Pacific Plate is responsible for heating through the crust to create the Hawaiian volcanoes. The Pacific plate moves over this hot spot, so gradually a line of volcanoes are punched through the sea floor and older volcanoes are moved away from the hot spot. Several lumps under the sea to the northwest of the current northwesternmost island in the chain are all that remain of what were once Hawaiian islands.

How many volcanoes are there in Japan?
It is unknown because there are more than a mill on the earth under sea and on land but there is a recorded number in history of eruptions more info from random site There are probably millions of volcanoes that have been active during the whole lifespan of the earth. During the past 10,000 years, there are about 1500 volcanoes on land that are known to have have been active, while the even larger number of submarine volcanoes is unknown.

Where are Volcanoes mostly located at?
Many of the world's active volcanoes are located around the edges of the Pacific Ocean: the West Coast of the Americas; the East Coast of Siberia, Japan, the Philippines, and Indonesia; and in island chains from New Guinea to New Zealand--the so-called "Ring of Fire". Recently, active volcanoes were also found in Iceland, the Kenya Rift Valley in Eastern Africa, Italy, and Hawaii. Looking at the locations of these volcanoes through the glasses of plate tectonics, we also notice that most volcanoes occur near the edges of the large "plates" that comprise the solid surface of Earth. Looking even more closely, we also notice that the dangerous explosive volcanoes, such as Mount St. Helens and Mount Pinatubo, that make the evening news are located where plates are crunching together. The quieter, "effusive" volcanoes, like Iceland and Hawaii, are found mostly where plates are coming apart or in the middle of a plate. .............................................................
