Japan Nankai Trough Earthquake 2024 (General)
I was mistaken regarding the location of quakes that can trigger Fuji. Apparently a quake in 1707 on the Nankai Trough was the last one to trigger a Mt. Fuji eruption.
In 1707, a rupture along its entire 600km length caused the second-biggest earthquake ever recorded in Japan and was followed by the eruption of Mount Fuji. Source.
