Onuma Park Hokkaido Complete Guide | Spectacular Scenery in All Seasons, Activities, and Gourmet Information Explained in Detail
Onuma Quasi-National Park, a representative scenic spot in the Dōnan region of Hokkaido. With the majestic Mt. Komagatake in the background, the natural beauty created by a group of lakes and ponds with 126 small islands floating on their surface continues to captivate visitors. This article provides thorough explanations of information to fully enjoy Onuma Park, from basic information about the park to how to enjoy each season, activities, and gourmet information.
Onuma Quasi-National Park | The Appeal of Dōnan’s Only Quasi-National Park
Onuma Quasi-National Park is Dōnan’s only quasi-national park, located in the central part of the Shimokita Peninsula in Hokkaido. The landscape created by the three lakes of Onuma, Konuma, and Junsainuma, formed by the eruption activity of Mt. Komagatake (elevation 1,131 m), an active volcano, and 126 small islands, boasts a beauty so remarkable that it has been selected as one of the New Japan’s Three Views.
The park’s total area is 9,083 hectares, spanning across three towns: Nanae, Shikabe, and Mori. The convenient access from the center of Hakodate City, approximately 20 km away, and about 33 km from Hakodate Airport, is also one of its attractions.
Characteristics of the Three Onuma Lakes
Onuma is the largest of the three lakes, boasting a perimeter of approximately 24 km and an area of 5.3 square kilometers. Many of the small islands floating on the lake’s surface are connected by bridges, and are developed as walking paths for island tours.
Konuma is located to the southeast of Onuma with a perimeter of approximately 16 km. It has a quieter and more serene atmosphere and is known as a spot suitable for bird watching.
Junsainuma is the smallest lake, and as its name suggests, Junsai (water shield) grows naturally here. In early summer, the water surface is adorned with water lilies and cow lilies, allowing visitors to enjoy beautiful waterside scenery.

The Appeal of Four Seasons | How to Enjoy Each Season
The greatest appeal of Onuma Quasi-National Park is the completely different appearance it presents in each of the four seasons. Each season is worth visiting, and the reason there are many repeat visitors is due to this characteristic.
Spring (April–June) | Season of Fresh Greenery and Flowers
From late April to May, after a long winter, spring arrives at Onuma. The cherry blossoms along the lakeshore begin to bloom, and the sight of fresh greenery sprouting is full of vitality. From mid-May onward, alpine plants such as skunk cabbage and dogtooth violet bloom, and forest walks become a pleasant activity.
In June, cow lilies and water lilies begin to bloom at Junsainuma, coloring the water surface. This period has relatively few tourists, making it a hidden gem season where you can enjoy nature in peace.
Summer (July–August) | Peak Season for Activities
Summer is the busiest season at Onuma Park. The “Onuma Lake Festival” held in mid-July, featuring fireworks displays and lantern floating, is cherished as a summer tradition by local residents.
With temperatures in the low 20s Celsius (around 70s Fahrenheit), it is an ideal season for activities such as canoeing, boating, and cycling. Operating hours are extended to 8 a.m. to 6 p.m. (July and August), allowing visitors to enjoy activities for extended periods.
Shirodai Ranch begins cattle grazing, offering pastoral scenery. Also, many families can be seen enjoying camping and barbecuing along the lakeshore.
Autumn (September–November) | Spectacular Fall Foliage
From mid to late October, the area around Onuma reaches its peak autumn foliage season. The slopes of Mt. Komagatake are dyed in red and yellow, and the scenery of fall leaves reflected on the lake’s surface is stunning.
Walking along the island-tour promenade allows you to experience walking through a tunnel of colored trees. Cycling around the lakeshore offers a chance to savor the varied foliage scenery.
In autumn, with clear air, the figure of Mt. Komagatake becomes more distinct, making it an ideal season for photography. Early morning mist often blankets the lake surface, creating a mystical landscape.
Winter (December–March) | World of Snow and Ice
In winter, Onuma transforms into a landscape of white. When the lake surface freezes from late January to early March, ice fishing for smelt becomes possible. Pitching a tent, drilling a hole in the ice, and fishing for smelt is an experience unique to winter.
The contrast between snow-covered Mt. Komagatake and the frozen lake surface presents a beauty entirely different from summer. Walking across the snowy landscape with snowshoes or cross-country skis is also popular.
In February, the “Onuma Hakodate Snow and Ice Festival” is held, featuring ice sculptures, snow statues, and a giant slide. Winter fireworks are launched, illuminating the winter night sky.
