The strongest month our cameras have measured so far, with pink moss fields at its feet.
Yes. May is the best full month our logger has measured so far, averaging 75/100 across 247 readings, with 24 of 31 clear mornings. The last of the snow cap still marks the summit, the shibazakura (pink moss) fields bloom into late May, and the only real planning hazard is Golden Week crowds from April 29 to May 5.

Average score by hour (JST), measured every 3 hours
May sits in a sweet spot: warm enough for comfortable mornings at the lakes, early enough that the rainy season has not arrived. High-pressure spells bring runs of clear days, and fresh green forests replace the browns of early spring around every viewpoint.
The snow line climbs through the month, but the cap usually stays visible into late May, so the classic white-topped profile holds for most visits.
Across 247 readings, May averaged 75/100, ahead of April and far ahead of June, which collapses when the rainy season arrives. The morning advantage persists, with the best scores clustering before mid-morning.
If you are choosing between late spring and early summer for a trip, our numbers say the answer plainly: go in May, not June.

April 29 to May 5 brings Japan’s biggest domestic travel wave. Visit after May 6 for the same weather with half the crowds and normal prices.
The Fuji Shibazakura Festival near Lake Motosu runs to late May. Pink moss fields with the snow-capped cone behind them are a May-only composition.
May afternoons are better than summer ones, but the sharpest views still come before mid-morning.
The rainy season typically starts in early-to-mid June. If your dates can slide, slide them earlier, not later.
