Hakone is a fantastic summer destination because its higher elevation provides a "High-Fidelity" escape from the sweltering heat and humidity of Tokyo. While the city may be over 35°C, Hakone’s mountain air is often several degrees cooler, especially near the shores of Lake Ashi. Summer in Hakone (July and August) is famous for its vibrant festivals, such as the Lake Ashi Water Festival on July 31st and the spectacular fireworks displays that follow. The lush green landscape is at its peak, and the "High-Fidelity" views of Mount Fuji, while sometimes obscured by summer haze, are most likely to be clear in the early morning. It is important to note that summer is a peak domestic travel season in Japan; expect crowds on the Hakone Tozan Railway and higher hotel prices. To avoid the busiest times, try to visit mid-week and utilize the Hakone Free Pass for seamless transport between the area's open-air museums and volcanic hot springs.
