Crowds During Cherry Blossom Season and Tips for Visiting
Weekends from late March to early April, when the cherry blossoms are at their peak, are expected to be particularly crowded. The parking lot tends to fill up early, so using public transportation is recommended. Weekdays and early morning time slots are relatively less crowded, allowing for leisurely enjoyment of the cherry blossoms.
Autumn Foliage Season | The Landscape of Rural Mountains Colored by Japanese Maples
While Iiyama Hakusan Forest Park is famous for its spring cherry blossoms, autumn foliage is also a highlight not to be missed. From mid-November to early December each year, Japanese maples and other maple varieties in the park turn vibrant colors, displaying strikingly red foliage.
Foliage Viewing Highlights
Near the Summit of Hakusan Mountain: The area around the summit of Hakusan Mountain (284 meters elevation) is a spectacular foliage viewing spot. The contrast between the colored Japanese maples and the distant mountains is beautiful and ideal for photography.

Around Iiyama Kannon: The Iiyama Kannon temple grounds and approach are also famous for autumn foliage, with the combination of historic temple architecture and foliage creating a picturesque landscape.
How to Enjoy the Foliage Season
Iiyama Hakusan Forest Park in autumn is less crowded than during cherry blossom season, allowing for quiet enjoyment of nature. Hiking while appreciating the foliage is recommended, allowing visitors to fully experience the calm autumn rural mountain landscape, different from the fresh greenery of early summer.
As temperatures drop this season, ensure proper cold-weather precautions and wear comfortable hiking attire. The foliage peak varies depending on weather and temperature, so it’s recommended to check the latest information before visiting.
