Oishi Park Seasons and the Fuji View

You can see Mt Fuji from Oishi Park whenever the mountain is clear of cloud: the park looks south across Lake Kawaguchi straight at it. The flowers follow the official calendar: lavender in early summer, as the town’s tourism site puts it, and kochia that turn red from mid to late October and golden-brown by early November (Yamanashi Tourism Organization, information as of 21 October 2026). The Herb Festival is over: it ended as an event with fiscal year 2025.

Can you see Mount Fuji from Oishi Park?

Yes, on a clear day. The park lies on the north shore of Lake Kawaguchi, and the town’s tourism site describes the view from it as Mt Fuji across the lake. Whether you see it depends on the cloud that day, and nothing about the park changes that. We have found no official figure for how often Fuji shows by month, so this page gives none.

The day-tour operators say the same: the weather decides the Fuji view, and they do not promise it. Guests’ reviews from the first week of November 2026 show both sides, from a clear, sunny day with the mountain seen from several viewpoints to a cloudy day when it never appeared. If your dates are flexible, decide by the forecast the evening before.

Autumn: the kochia

The kochia are the round shrubs planted along the flower path. The Yamanashi Tourism Organization’s colour guide (information as of 21 October 2026) gives this calendar, and says the weather and the temperature move it:

The red weeks are also the park’s busiest. On 13 October 2026 the town’s tourism site said that many visitors were coming to Oishi Park and that the roads and car parks round it were badly congested and jammed. It asked large buses to use temporary car parks and set down their passengers at designated places, asked visitors to allow plenty of time, and refused parking on the roadside or at nearby shops.

Early summer: the lavender

The town’s tourism site says only that lavender flowers at the park in early summer; it gives no dates, and the date ranges printed elsewhere are not the town’s. For years the lavender came with the Kawaguchiko Herb Festival. The Fujikawaguchiko Town office says the festival ended as an event with fiscal year 2025, that there will be no event with set dates any more, and that lavender can still be seen at Oishi Park and Yagizaki Park. Guides that still sell a June-to-July Herb Festival are out of date.

November and winter: the view itself

By November the kochia have gone golden-brown and the lavender is long over, so a visit from November into winter is about the lake and the mountain: the lakeside path, the water, and Fuji on the far shore when the cloud allows. Come early for a quieter path. The lake boats, including the Oishi Park Line from Funatsu Pier, are closed on Tuesdays 1, 8, 15 and 22 December 2026 and on Tuesdays 19 and 26 January 2027 (Fuji Gokokisen).

Picking a day from Tokyo

Since the mountain is the point and the weather decides it, book a tour you can cancel. Japan Visionary Tour’s Tokyo: Mt Fuji & Oishi Park & Lake Kawaguchi & Oshino Hakkai, from $49 on promotion, usually $82 (checked November 2026), can be cancelled free up to 24 hours before, so you can book a day, look at the forecast the evening before and move it if the cloud is coming. The day makes a 20-minute photo stop at Oishi Park, with Oshino Hakkai, the Chureito Pagoda and a thatched-roof village by Lake Sai.
