Oirase Gorge is a natural scenic area in Towada, Aomori Prefecture, where water flowing out of Lake Towada runs through the forest for about 14 kilometers. Along the walking trail, visitors can view a variety of waterscapes, including Ashura Stream, as well as Choshi Falls and Kumoi Falls at close range. Moss-covered rocks and fallen trees are common, creating a landscape where the stream and forest come together along the route.
Rather than walking the entire trail, travelers can also use buses to select specific areas to explore. Combining Oirase Gorge with Lake Towada makes it possible to experience the distinctive natural environment extending from the lake into the gorge within a single travel route.
Seasonal Guide to Oirase Gorge Scenery
For fresh greenery, mid-May to mid-June is a typical time to visit. Young leaves cover the gorge, blending with the green of the water and moss. When walking a long distance, checking the bus stops along each section in advance makes it easier to adjust the itinerary.
Autumn foliage is popular from mid- to late October. Red and yellow leaves can be viewed alongside the stream and waterfalls. Visitor numbers also increase in autumn, and traffic restrictions may be introduced for purposes such as protecting the natural environment. Travelers arriving by car should check the latest traffic restriction information in advance.
In winter, frozen waterfalls and icicles appear, creating scenery that differs greatly from the seasons of greenery and autumn foliage. However, JR buses traveling to Oirase Gorge from the Aomori and Hachinohe areas have a period of suspended service during winter. Guided frozen waterfall tours and snowshoe tours are also available during the season, making it important to choose a sightseeing method suited to snowy conditions.
Hittsumi: A Local Dish from Aomori
Hittsumi, a traditional dish from Aomori, is well suited for a meal after walking. It consists of hand-torn wheat dough simmered with vegetables and chicken. Ingredients grown in the Oirase region enhance the natural flavors of the dish. The warm soup gently warms the body after a walk.
