Tectonic plate boundary
Mount Adatara is associated with a convergent plate boundary, as are all of Japan's volcanoes.
Yes, volcanoes can form in the middle of tectonic plates, including the Pacific Plate. This type of volcano is usually known as a "hotspot volcano" and is caused by a hotspot of magma beneath the plate. The Hawaiian Islands are a prominent example of hotspot volcanoes that have formed in the middle of the Pacific Plate.
Mauna Kea is a convergent boundary. You're welcome. ;)
The type of volcano most likely to form a hotspot in the ocean is a shield volcano. These volcanoes are characterized by their broad, gentle slopes and are primarily built up by the flow of low-viscosity basaltic lava. Hotspots occur when a plume of hot material from the mantle rises to the surface, leading to volcanic activity, as seen in locations like the Hawaiian Islands. As the tectonic plate moves over the stationary hotspot, a chain of shield volcanoes can form.

It isn't on a plate boundary. It's on a hotspot.
Volcanoes are common on this type of plate boundary
convergence plate boundary, where tectonic plates move towards each other and collide, leading to subduction zones which are highly constructive regions of volcanoes. Volcanoes also form at divergent plate boundaries. A good example being the numerous Icelandic volcanoes which have formed over he Mid Atlantic Ridge.
The type of boundary associated with Icelandic volcanoes is the constructive plate boundary, where two plates slowly move apart and magma seeps up through the gap.
High mountain ranges without volcanoes are built at convergent continental plate boundaries. These vary greatly from divergent boundaries which cause volcanoes to form.
Yellowstone is not on a plate boundary, but is a 'hotspot' where magma seeps from the mantle to the surface, or near the surface. The case is the same for Hawaii.
Volcanoes on continents can develop at path convergent and divergent boundaries. They can occur where an oceanic plate subducts under a continental plate, producing a volcanic arc such as in the Cascade Range. Volcanoes can also occur in areas of rifting, such as Africa's Great Rift Valley, a developing divergent boundary. Where two oceanic plates converge volcanoes can develop underwater and eventually form volcanic islands. Volcanoes can also develop away from a plate boundary over a hot spot.
Shield volcanoes typically form on hot spots. These volcanoes have gentle slopes due to the low-viscosity basaltic lava they produce. Examples of shield volcanoes formed on hot spots include Mauna Loa in Hawaii and Galapagos Islands in Ecuador.
