Koagen-ji is a Rinzai sect (Chufuke branch) Zen temple located in Tanba, Hyogo Prefecture. Its mountain name is Zuigan-zan, and the primary deity is Shakyamuni Buddha. The temple is most famous for its "Tenmoku Kaede" (Tenmoku maple) foliage, making it one of the "Three Great Autumn Foliage Temples of Tanba" alongside Entoku-ji and Sekkan-ji. The temple grounds offer a profound sense of tranquility, with landscapes that shift beautifully through every season.
The temple was founded in 1325 by the Zen master Enkei Sokuo. Because Enkei Sokuo studied under a master from Mt. Tenmoku in China, Koagen-ji became known as the "West Tenmoku" (in contrast to the "East Tenmoku" of Soun-ji in Kai Province). Later, the temple was granted the name "Koagen-ji" by Emperor Go-Daigo. Although the temple suffered destruction during the Warring States period, it was restored in the early Edo period. It remains a prestigious site holding many cultural assets and items bestowed by the Imperial Court.

The temple grounds feature several historic structures that evoke a sense of deep history. Notable buildings include the "Butsuden" (Buddha Hall/Hōō-den), the "Hojo" (Abbot's Quarters) believed to have been rebuilt by Kōgan Genkei, and the "Tahoto" pagoda, which resembles a three-story structure but serves to house sacred sutras. Additionally, the ceiling of the "Shihō-rō" gate features exquisite historical paintings, symbolizing the rich cultural heritage of the temple.
The defining characteristic of Koagen-ji is its seasonal transformation. The peak season is autumn, when the Tenmoku Kaede maple trees turn vibrant colors, attracting many visitors. Spring also offers beautiful cherry blossoms. Visiting during the bright daylight hours allows for a detailed view of the garden and architecture, while visiting toward the late afternoon offers a more profound, meditative Zen atmosphere.

At Koagen-ji, visitors can immerse themselves in Zen culture. You can experience prayer and contemplation within a space that feels one with nature. The temple is also associated with the tradition of Shojin Ryori (Zen Buddhist vegetarian cuisine), offering a glimpse into the spiritual culinary culture of Zen. It is an ideal place to escape the bustle of daily life and find inner peace.
Nearby, you can visit the other two members of the "Three Great Autumn Foliage Temples of Tanba": Entoku-ji and Sekkan-ji. Additionally, the "Michi-no-Eki Ogaki" (Roadside Station) is about a 10-minute drive away, where you can enjoy local specialties and take a break. The entire Tanba area is surrounded by rich nature, making it perfect for a circuit of historic temples and scenic landscapes.
