Kogenji Temple is a historic Zen Buddhist temple located in Hikura, Aogaki-cho, Tamba City, Hyogo Prefecture. Belonging to the Myoshin-ji branch of the Rinzai school of Zen Buddhism, the temple is dedicated to Shakyamuni Buddha and is known for its beautiful autumn foliage, particularly the distinctive Tenmoku maples that turn the grounds into a colorful landscape each fall.
Kogenji is counted among the Three Great Autumn Foliage Temples of Tamba, together with Entsuji Temple and Sekiganji Temple. It is also the fourth temple on the Kansai Flower Temple Pilgrimage, a regional pilgrimage route connecting temples known for their seasonal flowers and natural beauty.
Kogenji was founded in 1325 by the Zen master Enkei Soyu. It became an important center of the Nakamine school of Rinzai Zen Buddhism.
In 1306, Enkei Soyu traveled to Yuan China, where he studied for approximately ten years under Zhongfeng Mingben, also known as Pu Ying Guoshi, at Mount Tianmu near Hangzhou. After returning to Japan, he sought a location resembling the sacred mountain he had known in China. Guided by a dream, he chose an area in Saji-go, Ogura, in the former Hikami District of Tamba Province, now part of Tamba City, and established the temple there.
In 1326, Emperor Go-Daigo bestowed the name Kogenji on the temple. In later years, Kogenji came to be known as Nishitenmoku, or Western Tianmu, in contrast to Seiunji Temple on Mount Tenmoku in present-day Yamanashi Prefecture, which became known as Totenmoku, or Eastern Tianmu.
In 1518, Kogenji became an imperial prayer temple under Emperor Go-Kashiwabara. Its abbots were granted the privilege of wearing purple robes, a distinction that contributed to the temple’s growth and influence. It subsequently developed into a major Zen institution with affiliated temples across Japan.
During the Sengoku period, however, the temple was burned down during Akechi Mitsuhide’s military campaign in Tamba, carried out under the orders of Oda Nobunaga. Kogenji was later revived in the early years of the Kyoho era, between 1716 and 1736, under the Zen master Tengan Myokei.
In 1790, the monk Kogan Gengei undertook further restoration work with support from the Kashiwabara Domain, including the construction of a tahoto-style pagoda. In 1807, Emperor Kokaku bestowed purple robes on Gengei, recognizing his standing and achievements.
In 2016, a family connected to Gengei donated a hanging scroll, an inkstone, and other objects that had originally been bestowed on him by Emperor Kokaku. These items returned to Kogenji, adding to the temple’s historical heritage.
Kogenji’s wooded grounds contain several historic buildings and traditional Buddhist structures. While the temple is worth visiting throughout the year, autumn is especially popular, when its Tenmoku maples transform the paths, gates, and temple buildings with vivid shades of red, orange, and gold.
Hoden Hall, also known as Hoo-den, serves as the temple’s main Buddha hall. It was rebuilt around 1720 by the Zen master Tengan Myokei during the Kyoho era. The principal image is a seated statue of Shakyamuni Buddha, traditionally attributed to Genshin, a renowned Buddhist monk associated with the Tendai school.
To the left of the principal image stands a statue of Emperor Go-Daigo dressed in Buddhist clerical robes, while memorial tablets dedicated to regional lords and other important figures are enshrined on the right.
The temple’s tahoto pagoda has an exterior that resembles a three-story pagoda. Inside, however, it contains a rinzo, a revolving bookcase designed to hold Buddhist scriptures. At the front is an image of Ka’un Bishamonten, a Buddhist guardian deity associated with good fortune and traditionally attributed to the Indian craftsman Vishvakarma.
The pagoda was built around 1790 under the direction of Kogan Gengei, with support from the Kashiwabara Domain. Its unusual combination of architectural appearance and interior function makes it one of the temple’s distinctive structures.
The main gate, known as Shiho-ro, was rebuilt around 1790 by Kogan Gengei. The upper floor enshrines Shakyamuni Buddha and the Sixteen Arhats, enlightened disciples revered in Buddhist tradition. Paintings of celestial maidens and Buddhist scriptures decorate the ceiling, adding artistic detail to the historic structure.
The Somon is another important entrance to the temple grounds, constructed with support from the Kashiwabara Domain during Gengei’s restoration efforts. The plaque above the entrance bears the inscription “Tankyusho-sho,” a phrase celebrating the site’s exceptional beauty. The calligraphy is attributed to Kogan Gengei himself.
The bell tower houses the temple bell used during Buddhist ceremonies and other important occasions. The original bell was surrendered for wartime use, and a replacement was cast in 1947. The present bell reflects the temple’s efforts to preserve its religious traditions in the postwar period.
Kogenji preserves a collection of Buddhist paintings, calligraphy, and religious objects that illustrate its long history as a Zen Buddhist center.

The temple’s designated cultural properties include a color painting of Myoon Benzaiten, a painting of Reimu Benzaiten, seven hanging scrolls depicting the Sixteen Arhats in monochrome ink, a Buddhist robe, and calligraphic works by prominent Zen masters. These include works attributed to Xueyan Zuqin, Gaofeng Yuanmiao, and Zhongfeng Mingben.
The grounds of Kogenji Temple are designated as a scenic site by Tamba City. Their combination of historic architecture, wooded slopes, stone paths, and seasonal vegetation makes the temple an important cultural landscape in the region.
Kogenji is particularly famous for its Tenmoku maples, which give the temple its reputation as a place to appreciate autumn leaves. The trees create colorful scenes around the traditional buildings and along the pathways, while the surrounding woodland enhances the sense of tranquility.
