Where to stand

Viewpoint: Lake Yamanaka · Lake Yamanaka, shore

Lined up with Kengamine, Mt. Fuji, 17.1 km away. Look towards 247° from north. It works across an area around this point, not only from the exact spot.

Good to know

Same shores as the diamond; at night or at dawn depending on the month. Mt. Ohira, Tanukiko and Kawaguchiko have their own days too.

The geometry is certain, but there is no official calendar: the dates are computed, with the moon as seen from the spot (parallax included). The moon shifts far more than the sun from day to day: the window is often a single day.
