Lake Ashi hosts chrysanthemum display from 17 October

At Lake Ashi (Ashi-no-ko) in Hakone, the Autumn Zaru Chrysanthemum Display is running from 17 October to 13 November 2026. The seasonal presentation gives visitors to Japan a specific reason to include the lakeside park in an autumn itinerary.

Chrysanthemums fill Onshi Hakone Park until 13 November

The display is taking place at Onshi Hakone Park's Lakeside Observation Hall, beside the southern part of the lake. The Hakone Town Tourism Association lists the event from 17 October to 13 November 2026, placing its final day within the current autumn travel period.

Odakyu Hakone, which operates the park under a management group with the Kanagawa Parks Association and Landflora, announced the presentation. Its programme places 80 potted chrysanthemums in the hall and outside it, with flowers in yellow, pink, white, purple and red. The event announcement for the 80 pots also connects the display with the park's autumn landscape.

The same announcement says the flowers will be distributed after the display on 14 November 2026 from 10am, subject to availability, to people who complete a questionnaire. That follow-up is separate from the display itself and gives the programme a defined closing activity.

Why the display belongs beside Lake Ashi

Onshi Hakone Park occupies the former site of Hakone Imperial Villa, a retreat associated with the imperial family. Its gardens and Lakeside Observation Hall look across the water towards the surrounding volcanic mountains, so the display is set within a named part of the landscape rather than at a distant venue.

The Japan Tourism Agency records that Lake Ashi formed about 3,000 years ago after an eruption of Mount Kami blocked the Haya River with lava and volcanic rock. The lake reaches 43.5 metres in depth and has a circumference of 19 kilometres, facts that explain the scale of the open setting around the park. The agency's Lake Ashi visitor description also identifies sightseeing vessels and Hakone Shrine as parts of the wider lakeside experience.

The link between the event and the place is therefore practical: the chrysanthemums are displayed in a hall overlooking a volcanic lake formed thousands of years ago. A visit can combine the seasonal presentation with the park's gardens and views without treating the display as a separate town-centre attraction.

Onshi Park adds a fixed stop to an autumn visit

The event matters for planning because its dates are fixed, while autumn colour changes across Hakone at different elevations. The display remains available through 13 November 2026, allowing travellers to place it alongside a lakeside walk or a cruise rather than relying only on an informal foliage forecast.

The official tourism listing places Onshi Hakone Park in the Hakone Town and Motohakone area. The park is served by Hakone Tozan Bus services, with Onshi Koen-mae used as the nearby stop. Lake cruises also operate on the water, linking northern and southern lakeside areas, although the event itself is on land.
