The hot spot volcanic activity is not dependent on the subduction and melting of oceanic crust. The hot spot simply appears to be a non-moving place in the Earth's mantle where heat rises from the interior.
Kobe, Japan is located near a convergent plate boundary, specifically where the Philippine Sea Plate is subducting beneath the Eurasian Plate. This subduction zone is known for producing frequent earthquakes and volcanic activity in the region. The tectonic forces at this boundary have contributed to the complex geology and seismic activity in the area.
It could be both. There are massive rising plumes (columns) of magma that are scattered all around the Earth. It doesn't make a difference wether it's on a boundary or not.
because it is at a converging boundary which means that the plates are coming together which causes earthquakes.This is because the Himalaya Mountains are a result of continent-continent collision and vulcanism in destructive boundaries results from subduction of oceanic plates. As the Indo-australian plate continues to collide with the Eurasian plate, subduction is no longer possible. The resulting stresses are relieved mostly from very large strike-slip faults. This results in much seismic activity, or earthquakes.-JenniPennehMore earthquakes and few volcanic eruptions occur in the Himalayas because volcanoes mostly occur when there is a transform boundary and subduction takes place between an oceanic plate and a continental plate. When the oceanic plate goes under the continental plate, subduction, the cool water from the ocean lowers the melting point of the rock it is under and allows magma to form easily. Then the magma rises upward(when magma is less dense than the rock surrounding it, it rises) and eventually goes through the surface creating a volcanic eruption.
Ocean-continental convergent boundaries can produce earthquakes and volcanic activity. As the ocean plates shift under each other they near their melting temperature and can form magma and solidify to form underwater mountain ranges.
Plate boundaries around Japan are convergent boundaries ie two plates are sliding towards each other. Japan has been formed as a result of the subduction of the Philippine Sea Plate beneath the continental Amurian Plate and Okinawa Plate to the south, and subduction of the Pacific Plate under the Okhotsk Plate to the north.
Convergent Boundary (Subduction Zone)
This type of boundary is called a convergent boundary or subduction zone, where the oceanic plate is pushed beneath the continental plate. The descending oceanic plate melts due to the heat and pressure, leading to volcanic activity and the formation of volcanic arcs.
It's called destructive plate margin/boundary, or convergent plate margin though this term applies to all plate margins where two plates are moving towards each other (such as continental + continental or oceanic + oceanic).
Oceanic crust is denser than continental crust due to its composition of basaltic rock and higher iron content. This density difference causes oceanic crust to sink beneath the lighter continental crust at subduction zones, creating a convergent boundary. The descending oceanic plate creates deep oceanic trenches and can trigger volcanic activity when it melts and rises to the surface.
A convergent boundary that does not have a subduction zone is a continental-continental convergent boundary. At this type of boundary, two continental plates collide and crumple, leading to the formation of mountain ranges, such as the Himalayas. Since both plates are buoyant and primarily composed of continental crust, neither plate is forced beneath the other, unlike in oceanic-continental or oceanic-oceanic boundaries.
Subduction zones, trenches and volcanic islands: the boundary that is oceanic. Trenches and volcanic islands: an oceanic-continental boundary. Folded mountain ranges: a continental and continental collision.

subduction zone or continental plate
A convergent boundary forms when an oceanic plate is pushed under a continental plate. This process, known as subduction, can result in the formation of deep ocean trenches, volcanic arcs, and earthquakes.
This process is known as subduction. When an oceanic plate collides with and is forced underneath a continental plate, it creates a subduction zone. The descending oceanic plate melts due to the intense heat and pressure, causing volcanic activity and the formation of mountain ranges on the continental plate.

Converging (destructive) plate boundary: where two plates collide. Diverging (constructive) plate boundary: where two plates move away from each other. Transform plate boundary: where two plates move, or grind, past each other. Like the boundary in California.
