The festivities are distributed over six consecutive days across multiple scenic bays around Lake Ashinoko. This structure allows visitors to experience a unique blend of solemn Shinto ceremonies, cultural entertainment, and world-class pyrotechnic artistry in a breathtaking natural environment.

Why is it popular?

This festival is profoundly popular due to its signature underwater fireworks displays, which create mesmerizing, perfect semi-circles of light across the lake’s surface. The dramatic, reverberating echoes of the explosions against the surrounding volcanic mountains provide a sensory experience that is truly unparalleled.

It remains a premier destination because it offers the perfect equilibrium between deep cultural immersion and vibrant, high-energy summer fun.

Tips before you go

• Ensure you arrive at your selected viewing vantage point early in the evening to secure an optimal, unobstructed position for the show.
• Pack a light, wind-resistant jacket or wrap, as temperatures around the alpine lake can drop significantly after the sun sets.
• Carry high-quality, portable insect repellent, as the lush, natural lakeside environment can be active during the warm summer evenings.
• Thoroughly review local bus and train schedules in advance, as public transportation becomes exceptionally crowded immediately following the fireworks finale.
• If you desire a premium dining experience at a lakeside hotel, finalize your table reservations well before your arrival to avoid disappointment.

Tips for First-Time Visitors

• Embark on a daytime sightseeing boat cruise to gain a comprehensive, panoramic perspective of the various festival bays you will return to enjoy at night.
• Prioritize wearing comfortable, sturdy walking shoes, as the scenic pathways surrounding the historic shrine and the lakeshore can be uneven and involve substantial exploration.
• Dedicate ample time during the daylight hours to visit the iconic Hakone Shrine, allowing you to fully appreciate its masterful architecture and the famous torii gate before the evening crowds converge.
• Maintain excellent hydration by utilizing the frequent, convenient local vending machines or shops, as the summer humidity in the Hakone valley can be quite intense during the day.
• Consider acquiring a comprehensive Hakone Free Pass, which provides seamless, unlimited navigation across the local buses, mountain trains, and even the sightseeing boats throughout your festival visit.
• While it is natural to want to record everything, make sure to set your camera down for several minutes to allow yourself to fully absorb the awe-inspiring reality of the fireworks dancing upon the water.
