Complete Guide to the Area Around Lake Shirakawa, Yamagata Prefecture | Thorough Explanation from the Spectacular Submerged Forest to Hot Springs and Activities
Lake Shirakawa, located in Iide Town, Yamagata Prefecture, is a scenic spot known throughout the country for its fantastical submerged forest that appears during the spring snowmelt season. Although it is an artificial lake formed by the Shirakawa Dam, its beautiful landscapes and rich natural environment throughout the four seasons captivate visitors. This article introduces the attractions around Lake Shirakawa, practical access information, and nearby facilities, presenting all the charm this region has to offer.
The Submerged Forest of Lake Shirakawa: A Mystical Sight Only in Spring
The Mechanism Behind the Submerged Forest
The submerged forest at Lake Shirakawa is a limited-time spectacular view that can only be seen for approximately two months from late March to mid-May. The large amount of snow accumulated in the Iide Mountains begins to melt with the arrival of spring, and this snowmelt water flows into the Shirakawa Dam. The water level rises significantly compared to normal times, causing the white willow trees growing along the shore to become submerged up to their trunks, creating a mysterious scene as if trees were growing from the lake surface.
This phenomenon is a unique landscape created by the combination of natural cycles and an artificial dam, something that can be seen nowhere else. The willows that receive new growth at the beginning of the fresh green season sprout young leaves, with the snow-covered Iide Mountains as a backdrop and the lake surface shining as it reflects the sky, creating a deep emotional impact on all who visit.
The Most Beautiful Season and Best Timing
The submerged forest is most beautifully seen from mid-April to early May. During this period, the lake reaches full capacity, and the willow trees display their most vibrant new green. Particularly around the Golden Week holidays, the contrast between remaining snow and fresh greenery reaches its peak, attracting many photography enthusiasts and photographers.
The early morning hours are especially recommended. When morning mist hangs over the trees, a fantastical landscape unfolds like a scene from a story. The lake surface is calm like a mirror, and the changing light as the morning sun shines is breathtakingly beautiful. On weekday early mornings, even during Golden Week, you can enjoy the spectacular views in relative peace and quiet.
Lighting-Up Events
In recent years, lighting-up events have been held during the submerged forest season. In the 2026 season, lighting is scheduled for April 18-19, April 25 through May 10, and May 16-17. The submerged forest emerging in the darkness of night creates a different kind of fantastical atmosphere from daytime, providing visitors with a special experience.
During the lighting-up period, local restaurants and other food stalls set up inside Shirakawa Lake Shore Park, selling local gourmet food. This is a precious opportunity to enjoy local flavors while viewing the submerged forest at night.

Access Information: How to Get to Lake Shirakawa
Access by Car
Car access to Lake Shirakawa is convenient. It is about 40 minutes by car from the Nanyo-Takahata IC or Yonezawa-Chuo IC on the Tohoku Central Expressway. The typical route involves following local roads heading toward the Lake Shirakawa area.
When using a navigation system, set “Shirakawa Dam Lake Shore Park” or “Shirakawa Hot Spring Iide Shirakawa Lodge” as your destination. Although roads are well-maintained, winter snow requires studded tires.

When parking, use designated parking areas in the prefecture roads or park. Roadside or unauthorized parking is inconsiderate to other users and may obstruct emergency vehicle passage. Please observe proper parking etiquette.
Access by Public Transportation
When using public transportation, Hamazen Tsubaki Station on the JR Yonezawa-Sakugi Line is the nearest station, but as there is distance from the station to Lake Shirakawa, taxi use is necessary.

Important Precautions and Etiquette When Visiting
Nature Protection and Submerged Forest Conservation
The submerged forest at Lake Shirakawa is a valuable natural landscape, and its protection is important. Along the shore and in the vicinity of the submerged forest, be careful not to damage plants or litter. It is important for each individual visitor to be conscious of environmental conservation to preserve this beautiful landscape for future generations.
When experiencing canoe or SUP activities, be careful not to collide with willow trees and exercise consideration to minimize impact on the natural environment.
Photography Etiquette
The submerged forest is an excellent photo spot, but please also consider other tourists. When using a tripod, be careful not to block pathways and avoid occupying the same location for long periods. If using a drone, prior permission may be required, so check with relevant authorities.
During early morning photography, car engine sounds and door-closing noises resonate in the quiet environment, so consideration for surroundings is necessary.
Clothing and Belongings
The area around Lake Shirakawa is in a mountainous region, so temperatures are cooler than in lowland areas. Especially in early morning and evening, it can be quite cold, so bringing a jacket is recommended. In early spring, the ground may be muddy from snowmelt, so waterproof shoes or boots are appropriate.
On sunny days, bring a hat and sunscreen. Insect repellent spray is also useful.
