Hakone-en Summer Night Festa — 6,000 fireworks launched over the lake during the two days
The confirmed fireworks launch dates for this festival are listed below.
Hakone-en Summer Night Festa is a lakeside fireworks show launched over Lake Ashi in Hakone, Kanagawa. In 2026 it runs on August 2 and 3, with about 3,000 shells each night (around 6,000 in total) rising from Hakone-en Bay between 8:00 and 8:20 pm. Highlights include starmine barrages whose echoes rebound off the surrounding mountains and water starmine blooming low over the lake surface. Crowds stay at a relaxed 3,000–4,000: spread a leisure sheet on the lawns for free viewing, or take the paid seats (¥2,000) on the sandy shore. Festival stalls and food trucks add to the appeal, and the event pairs easily with sightseeing in Hakone.
Hakone-en Summer Night Festa stages its fireworks over Lake Ashi from the grounds of Hakone-en, a lakeside resort in Hakone Town, Kanagawa. The 2026 edition takes place on Sunday, August 2 and Monday, August 3, launching roughly 3,000 shells per evening — about 6,000 across the two nights — from 8:00 to 8:20 pm above Hakone-en Bay. The setting is what sets this event apart: starmine sequences echo off the mountains ringing the lake, while water starmine opens just above the calm surface, lighting up the water in an instant. You can choose how to watch. The lakeside lawn is roomy enough to spread a leisure sheet and enjoy the show for free, while paid seats (¥2,000) on the sandy beach sit closer to the launch site. Attendance of around 3,000–4,000 keeps lines and crowds manageable, making this an easy addition to a Hakone sightseeing itinerary. Festival stalls and food trucks line the grounds with a small carnival feel. Access is by bus from Hakone-Yumoto Station (about 65 minutes; a short walk from the Hakone-en stop), or by car via Ashinoko Skyline Hakone-Toge IC (about 15 minutes); a 327-space paid car park is on site (cars ¥1,000 per entry).
