Karuizawa Summer 2026: The Cool Highland Escape from Tokyo (Complete Guide)

Karuizawa (軽井沢) is Tokyo's oldest and closest highland retreat. At 1,000m elevation, summer temperatures stay 20-24°C when Tokyo hits 32-35°C. 90 minutes from Tokyo Station via Hokuriku Shinkansen (JR Pass covers it). Since the 19th century Meiji era, this has been where Japanese elite and foreign missionaries escaped summer heat — and it still is.
