This forest, protected by strict forest conservation policies of the Owari Domain for over 400 years, is now certified as a forest therapy base where health promotion effects have been scientifically proven, becoming a healing space. This article comprehensively introduces information you should know before visiting Akasawa Nature Recuperation Forest, including its charm, access methods, hiking courses, forest railway, and seasonal highlights.
What is Akasawa Nature Recuperation Forest? History and Characteristics
One of Japan’s Three Most Beautiful Forests, a Treasure of Kiso Hinoki
Akasawa Nature Recuperation Forest is a natural forest of Kiso Hinoki cypress, one of Japan’s three most beautiful forests alongside Aomori Hiba and Akita Cedar. Spanning approximately 728 hectares, this forest is home to numerous natural Kiso Hinoki trees over 300 years old, whose majestic landscape overwhelms all who visit.
Kiso Hinoki is known as a premium construction material with fine grain, pleasant aroma, and excellent strength and durability. It is also used as sacred timber in the Ise Shrine’s Shikinen Sengu ceremony, and Akasawa Nature Recuperation Forest is the homeland of these sacred trees.
400 Years of Forest Protection History
The current state of Akasawa Forest is due to strict forest conservation policies of the Owari Domain that began in the mid-1600s. During the Edo period, the forests of Kiso were in critical condition due to excessive logging, but the Owari Domain established a strict law: “One tree, one head,” prohibiting the felling of the “Five Trees of Kiso”—Hinoki, Sawara, Asunaro, Koyamaki, and Nezuko.
Through this world-leading sustainable forest management policy, Akasawa Forest has been protected for over 400 years, forming the beautiful natural forest we see today. However, Akasawa Nature Recuperation Forest is characterized by being a secondary forest rather than a primeval forest, developed through long-term protective management.
Value as the Birthplace of Forest Bathing
In 1982, Japan’s first forest bathing convention was held at Akasawa Nature Recuperation Forest, officially designating it as the “birthplace of forest bathing.” Forest bathing is a health practice that involves engaging all five senses to experience nature in the forest and refresh body and mind.
In 2006, it became the first forest therapy base in Japan, with the health promotion effects of forest bathing scientifically verified. The refreshing aroma of Kiso Hinoki was selected for the Ministry of the Environment’s “100 Selections of Fragrant Landscapes,” bringing profound relaxation effects to all visitors.

Akasawa Forest Railway | Touring the Forest by Trolley Train

Spring brings fresh greenery, summer offers deep green, and autumn features red leaves of Akayashio and Doudantsutsji, with golden foliage of Shimoji and Mizunara painting the window view.
