Akasawa Natural Recreation Forest in Kiso, Nagano is Japan's first designated natural recreation forest, protected since the early Edo period (1603-1867). In the mid-1600s, the forest was placed under strict protection policy by the Owari Domain, establishing a conservation legacy that spans over 400 years. This historically significant forest management system helped preserve what would become one of Japan's most treasured natural areas.

Recognized as one of Japan's three most beautiful forests, Akasawa spans 728 hectares and is home to natural Kiso cypress trees over 300 years old. The Environment Ministry has selected it for its list of One Hundred Most Fragrant Scenic Areas, reflecting both its natural beauty and cultural significance as a protected forest ecosystem. The forest is considered the birthplace of Shinrin-yoku, or 'forest bathing', making it a cornerstone of Japan's wellness tourism movement.

Visitors can explore the forest through seven scenic walking trails that wind through towering cypress groves, each designed to showcase different aspects of the forest ecosystem. The forest offers eight walking courses where strolling is considered to have medicinal effects. A key attraction is the Akasawa Forest Railway, a historic logging railroad that now operates as a scenic ride through the forest, offering visitors a unique perspective on the area's forestry heritage. The railway experience costs ¥500-¥800 for adults and ¥500 for children aged 4 through elementary school.

The forest is open from April 29 to November 7, with free admission to the forest itself. Parking fees apply at ¥600 for standard-sized cars. The forest is located in Agematsu town in the Kiso Valley of Nagano Prefecture, accessible by train to Agematsu Station followed by local transport. Accommodation is available at the Kyoraiso Guest House within the forest grounds, and the facility provides toilets, drinking fountains, and accessible facilities for all visitors.

What other travelers are saying about Akasawa Natural Recreation Forest, Agematsu

A really beautiful place, well worth going rain or shine! Don’t let rain deter you - I hiked in light rain and it made for a wonderful experience. The cypress trees are truly majestic and there are different trails you can take (1-2h) to see varied scenery. The trails are not difficult, and there is even one where people who are differently abled could do (wheelchair friendly, too). The river is such a highlight and worth dipping in, even if it’s cold! The caretaker that I met, Sato-san, was so kind to explain to me the differences between the cypress trees and show me other details of nature I would have missed. Everyone from the gift shop owner to the bus drivers were so nice! Please visit if you’re in Kiso!

Peaceful place to enjoy fall colours, forest bathing, trails and even a little train ride. Well marked trails, beautiful nature, and on every trail you can find a little station providing rubber stamps for collectors. There is a restaurant serving warm food open from 10:00 to 14:30. No picnicking facilities, but a bench in the park or o large rock/boulder on the river side can serve as a picnic table :)

This is a hidden gem in the midst of overtourtism in Japan. Instead of crowded and over pricy kamigochi 上高地, you should come here for the true beauty of nature and tranquility. Nestled between nagoya and kisofukushima, a small town called Agematsu, then take 30 min bus directly to this forest. The forest courses are not difficult, but interesting.

The birthplace of forest bathing (shinrin-yoku). I visited in late August, and even with the rain, it was an awesome experience. There are several easy and relaxing walking paths to choose from. The wood from this area has been used in many sacred places all over Japan, especially in the construction of Ise Jingu. This forest is undoubtedly one of the most beautiful I've ever seen. It made me feel so much calmer and happier. I totally recommend it.
