How do you calculate it?
For each spot we work out the direction of Fuji's summit and how high it appears above the horizon, allowing for the curve of the Earth and normal refraction. Then, for every day, we find the moment the sun (or moon) sinks to, or rises from, that height and measure how far left or right of the summit it is. Within about 0.4° the sun's disc sits on the summit: that is a Diamond Fuji. Pearl Fuji is the same with a moon at least half lit.
Summit bearing 248.7°, apparent height 1.45°, distance 105 km. Times are Japan time. Moving a few hundred metres along the shore shifts the best day by a day or so.
