Japan is a magmatic island arc, and involves the subduction of oceanic crust containing volatiles (water and other fluids) below continental crust. This lowers the melting point of the rock and causes melting, giving you magma to form your volcanoes. Have a look for the sangabawa and ryoku paired metamorphic belts for a bit more advanced reading.

How did mount unzen form?

Mount Unzen formed as a result of volcanic activity associated with the subduction of the Philippine Sea Plate beneath the Eurasian Plate. This process caused magma to rise and accumulate, leading to the development of a series of stratovolcanoes over millions of years. The last major eruption occurred in 1991, significantly altering the landscape and demonstrating the ongoing volcanic activity in the region. The complex structure of Mount Unzen includes multiple peaks, each formed through different eruptive phases.
