Oishi Park (大石公園) is a free lakeside park on the north shore of Lake Kawaguchiko, looking south across the water to Mount Fuji. Its 350-meter flower walk is planted with more than 90 kinds of flowers through the year. The best-known display is lavender, which flowers from about mid-June into mid-July, with the Kawaguchiko Herb Festival from late June to mid-July; the kochia turns red in autumn. The retro sightseeing bus from Kawaguchiko Station takes about 30 minutes.

What Oishi Park is for
Oishi Park is the north shore's main viewpoint: flowers in front, the lake in the middle and Mount Fuji behind. That is the whole idea, and it works best when the mountain is out, so time the visit around clear weather as much as around the flower calendar.
Lavender usually flowers from about mid-June into mid-July, shifting with each year's weather; Yamanashi's official tourism site places the Herb Festival and the lavender peak from late June to mid-July. In autumn the rounded kochia bushes turn red. The rest of the year the flower walk changes with the season, and the park building, the Kawaguchiko Natural Living Center, has a shop.
Getting to Kawaguchiko, the cruise and the ropeway are covered in the Lake Kawaguchiko guide; this page covers the park itself.

Best Time to Visit Oishi Park
Best time to visit Oishi Park: About mid-June to mid-July for lavender; autumn for red kochia; clear mornings for Mount Fuji. Weekday mornings are generally quieter than weekends and public holidays.
- •Lavender flowers from about mid-June to mid-July, with the Herb Festival from late June to mid-July.
- •The rainy season overlaps the lavender, so Mount Fuji is often hidden then; a clear morning is worth waiting for.
- •Kochia turns red in autumn, when the air is clearer than in summer.
The Herb Festival runs from late June to mid-July. Bloom timing shifts with the weather, so check the current year before planning a trip around it.
The kochia bushes turn from green to red; exact timing varies by year.
Fewer flowers, but the clearest air for Mount Fuji across the lake.
