Nestled in the mountainous region of Toyota City, Aichi Prefecture, Korankei (香嵐渓) is one of Japan’s most renowned scenic spots for autumn foliage. This picturesque gorge, carved by the Tomoe River, draws visitors year-round with its breathtaking natural beauty and charming historic townscape. Particularly famous for its maple trees and the annual Momiji (autumn leaves) Festival, Korankei is a wonderful destination for photographers, hikers, and anyone looking for an easy nature-filled day trip from Nagoya.
A Brief History of Korankei
- First maple trees were planted in 1634 by Sanei Kazuhisa, the 11th head priest of Kojakuji Temple—reciting one verse of the Heart Sutra for every tree planted.
- The valley name “Korankei” is inspired by the fragrant breeze and energy of the mountain.
- Over 4,000 maple trees of 11 varieties grow in the valley.
The history of Korankei dates back to the early Edo period. In 1634, Sanei Kazuhisa, the 11th head priest of Kojakuji Temple, began planting maple and cedar trees along the path from the Tomoe River to the temple grounds. He is said to have recited one verse of the Heart Sutra for each tree he planted as a spiritual offering to nature.
Over time, the local residents of Asuke continued planting more maple trees, turning the valley into a scenic and sacred grove. During the Taisho and early Showa periods (1920s–1930s), youth groups and women’s associations participated in volunteer efforts to plant additional maples in the surrounding forest, further enhancing the beauty of the landscape.
In 1930, the name “Korankei” was officially given to the area. The name was inspired by a poetic description of the fragrant breeze ("Ko") and the dynamic mountain spirit ("Ran") that flowed from Mt. Iimori across the valley and through the maple trees lining the path to Kojakuji Temple.
Today, Korankei is home to over 4,000 maple trees of 11 different species, including varieties such as Iroha-momiji and Yamamomiji. The valley has become one of Japan’s most beloved autumn foliage destinations, attracting hundreds of thousands of visitors each year.
The Seasons in Korankei
Though Korankei is most famous for its autumn foliage, it is a wonderful outdoor destination year round.
Spring: From March to April, Erythronium japonicum (katakuri) flowers bloom in soft violet hues, carpeting the forest floor. Mid-April sees the emergence of wild mountain plants.
Summer: The area transforms with fresh greenery. Locals and visitors alike enjoy cooling off in the river, shaded walks, and summer festivals.
Autumn: The most celebrated season at Korankei. From mid-November to late-November, 11 types of maple trees decorate the valley in shades of crimson, gold, and orange. This period also marks the Momiji Festival, featuring light-ups, food stalls, performances, and traditional events.
Winter: The gorge becomes covered in snow which contrasts beautifully with the vermillion Taigetsu Bridge. In January, the Nanakusa Festival is hosted at Asuke Hachimangu Shrine.
