3D model of Tectonic Plates’ disposition around Japan.
You can see that Pacific plate and Philippine Sea plate are sinking under the Japanese Archipelago.
Most part of the Japanese Archipelago are on Eurasian plate*.
Philippine Sea plate is sinking under Eurasian plate. Sunk part (slab) is quite distorted.
Izu peninsula is on Philippine Sea plate, and colliding Japanese Archipelago around Mt. Fuji.
Philippine Sea plate is moving to northwest by about 5.6 cm per year.
Pacific plate is sinking under both Eurasian plate and Philippine Sea plate. It is moving to northwest by 8.0 cm per year.
