Traveller notes on Karuizawa in February
Other months in Karuizawa
Karuizawa's forum calls May one of the most pleasant months — its elevation keeps it noticeably cooler than Tokyo, with a day-to-night temperature swing of around 10°C that catches some visitors out. Regulars recommend layers for exactly that reason, plus a rain jacket just in case, and flag the first week of May (Golden Week) as considerably busier than the rest of the month.
