Hakone’s event calendar follows the seasons closely, with fire festivals in winter, cherry blossom illuminations in spring, hydrangea train rides in summer, and autumn foliage night viewings in fall. Most events are concentrated around the Hakone Yumoto and Lake Ashi areas, and the Hakone Free Pass covers transport to nearly all of them. Book accommodation 2-3 months ahead for festival dates, especially during the summer Daimyo Gyoretsu and New Year period. See the Hakone weather by month guide for detailed climate data. This Hakone travel guide covers everything you need to plan your trip.
Hakone Events & Festivals: Winter (December to February)
Dondoyaki Fire Festival (January 15)
Held on January 15 at various shrines around Hakone, this traditional fire festival burns New Year decorations (shimekazari and kakizome calligraphy) in large community bonfires to send off the Toshigami deity. The largest gathering is at Hakone Shrine, where a 5-metre pyre is lit at dusk. Mochi is roasted over the flames and shared among attendees. The festival starts around 17:00 and runs until 20:00. Free admission. The bus from Hakone Yumoto to Moto-Hakone (35 minutes, 960 yen) runs on a reduced winter schedule, so check the last return bus time. Read our best time to visit Hakone to pick the right season.
Lake Ashi Winter Fireworks (select dates in December and January)
On 4-5 selected evenings in December and January (typically Saturdays), a 20-minute fireworks display launches from a barge in the centre of Lake Ashi. The fireworks reflect off the lake surface and, on clear nights, are framed by the silhouette of Mount Fuji. Best viewing spots are along the lakeside promenade near Hakone-machi Port or from the deck of a pirate ship (special evening sailings run on fireworks nights, 2,500 yen). The display starts at 20:00. Wrap up warmly: lakeside temperatures hover around 0-3°C (32-37°F) in December and January after dark. Our things to do in Hakone covers all the major sights.
Hakone Events & Festivals: Spring (March to May)
Hakone Cherry Blossom Illumination (early to mid-April)
During peak cherry blossom season (roughly April 5-15), the Hakone Tozan Railway illuminates the cherry tree corridor between Hakone Yumoto and Gora stations after sunset. The trains slow through the lit section, and passengers can view the blossoms from inside the carriage. The illumination runs from 18:00 to 21:00. A special night train ticket costs 500 yen in addition to the regular fare (320 yen for the full line). Miyagino Bridge near Gora Station is a popular photography spot where you can capture the illuminated train passing through the blossom tunnel. Our Hakone neighborhoods guide explains each area in detail.
Hakone Daimyo Gyoretsu (November 3)
One of Japan’s most elaborate period parades, this festival recreates a feudal lord’s procession (daimyo gyoretsu) along the old Tokaido road. Over 400 participants in full Edo-period costume, including samurai, porters, and princesses in palanquins, march a 2 km route from Sounji Temple to the Hakone Yumoto area. The procession starts at 10:00 and takes about 3 hours. The route passes directly in front of Hakone Yumoto Station, making it easily accessible by train from Tokyo. Spectators line the roadsides; arrive by 09:30 for a good viewing spot near the station. November 3 is Culture Day, a national holiday, so expect larger-than-normal crowds across the entire Hakone area. See where to stay in Hakone for recommendations by area and budget.
Hakone Events & Festivals: Summer (June to August)
Hakone Hydrangea Train (mid-June to mid-July)
Along the Hakone Tozan Railway between Hakone Yumoto and Gora, over 10,000 hydrangea bushes bloom in shades of blue, purple, and pink during the rainy season. The train line is colloquially called the “Hydrangea Train” (Ajisai Densha) during this period. Trains slow through the densest sections, especially around Tonosawa and Ohiradai stations. After dark, the flower clusters are spot-lit, and the train runs special evening services from 18:00 to 21:00. The regular train fare of 320 yen applies; no extra ticket is needed for daytime viewing. The seasonal illumination has a 500 yen supplement. For practical information, check our Hakone travel tips and FAQ.
Lake Ashinoko Summer Festival (August 5)
This one-day summer festival centres on a large fireworks display over Lake Ashi, with 3,000 shells launched from a floating platform. Food stalls selling yakisoba, kakigori, and grilled squid line the lakeside from 16:00, and the fireworks start at 19:30, lasting 40 minutes. The display is visible from Moto-Hakone, Hakone-machi, and the pirate ship evening sailing. Hakonejinja Shrine holds a torchlit ceremony at 18:00 preceding the fireworks. Free admission to the lakeside viewing areas. Special shuttle buses run from Hakone Yumoto Station to Moto-Hakone from 17:00 to 22:00 (1,200 yen round trip).
Hakone Events & Festivals: Autumn (September to November)
Hakone Autumn Leaves Night Viewing (November)
Throughout November, the Hakone Tozan Railway illuminates maple and ginkgo trees along the tracks between Hakone Yumoto and Gora from 18:00 to 21:00. The section around Chokoku-no-Mori Station is particularly brilliant, with dozens of Japanese maples turning deep crimson above the tracks. The illumination coincides with the regular train schedule, so passengers on any evening train during the period will pass through the lit section. A 500 yen night viewing supplement applies. The Hakone Open-Air Museum also extends its hours until 19:30 on Saturdays in November for a separate “Night Museum” event, with sculptures lit against the autumn foliage (standard admission applies, 1,600 yen).
Sengokuhara Susuki Festival (late October to late November)
During the peak pampas grass season, the Sengokuhara fields host a low-key festival with a small craft market on weekends (pottery, textiles, local honey) and weekend evening illumination of the grass fields from 17:00 to 20:00. Local food trucks sell oden, grilled mochi, and hot amazake (sweet rice drink, 300-500 yen per item). The boardwalk through the grass has solar-powered path lights after dark. Free admission. Access via Hakone Tozan Bus from Odawara or Hakone Yumoto to Sengoku bus stop, then a 10-minute walk.
