Iko-ji Temple is a historic temple of the Tōfuku-ji school of Rinzai Zen Buddhism, located in Someha-cho, Masuda City, Shimane Prefecture. The temple is known by the mountain name Takuzōzan and enshrines Yakushi Nyorai, the Buddha traditionally associated with healing and medicine.
What makes Iko-ji particularly special is its connection with Sesshū Tōyō, the celebrated Muromachi-period ink painter and Zen monk. The temple grounds include a beautiful Japanese garden associated with Sesshū, and the garden has been designated as both a National Historic Site and Place of Scenic Beauty.
With its combination of Zen culture, history, traditional architecture, and landscape design, Iko-ji offers visitors a peaceful opportunity to experience an important part of Masuda’s cultural heritage.
The history of Iko-ji can be traced back to Sōkan-ji Temple, a Tendai Buddhist temple founded in 1363 during the Muromachi period. Supported by the powerful Masuda clan, Sōkan-ji flourished and was once so prosperous that it was known as one of the leading temple complexes in western Japan.
As political instability spread during the Sengoku period, however, the temple gradually declined. During the Tenbun era in the 16th century, Masuda Munekane, the 17th head of the Masuda clan, promoted its revival. At this time, Iko-ji, which had previously served as a sub-temple of Sōkan-ji, was extensively developed.
The two temples eventually came to be referred to together as Sōkan-Iko-ji. Today’s Iko-ji carries on this long history and reflects the close relationship between Buddhism and the Masuda clan.
There is also a tradition that the temple’s chief priest was appointed following a recommendation from the shogun of the Muromachi shogunate. If so, this reflects the considerable prestige and status that the temple held during the period.
The most famous feature of Iko-ji is its Japanese garden, which is traditionally attributed to Sesshū, one of Japan’s greatest ink painters. Sesshū is said to have stayed in the area during the Bunmei era, from 1469 to 1487, and served as the temple’s fifth chief priest.
According to tradition, he also created the garden during his time at the temple. Although the present garden was reconstructed after a major fire in 1729, it continues to reflect the landscape philosophy associated with Sesshū and has been designated as a National Historic Site and Place of Scenic Beauty.
The garden is designed as a pond-centered garden with a partially circuit-style walking route, allowing visitors to appreciate the landscape from different viewpoints while strolling around part of the pond.
At the center of the pond is an island representing a tortoise, while a carefully arranged group of stones on the opposite side symbolizes a crane. These motifs reflect the traditional Hōrai concept, an ideal paradise associated with longevity and immortality in East Asian thought.
The tortoise island incorporates several specially shaped stones, including stones representing the tortoise’s shell and head. Together, the stones create an impression of a tortoise emerging from the landscape. The crane is represented more abstractly through stone arrangements, creating an elegant balance between realistic and symbolic forms.
On the slope behind the pond, a dry waterfall and a group of three sacred stones represent Mount Hōrai, the mythical mountain believed to be inhabited by immortals. The garden makes skillful use of the natural terrain to create a three-dimensional landscape, demonstrating the sophisticated artistic approach associated with Sesshū.
The garden changes dramatically with the seasons. In spring, weeping cherry trees and azaleas add delicate colors to the landscape, while autumn brings brilliant foliage.
During the autumn season, the colorful trees reflected on the surface of the pond create a particularly beautiful scene. The garden is also a popular destination for visitors interested in traditional Japanese landscape photography.
The main gate at the entrance to Iko-ji is traditionally said to have been relocated from the main gate of Nanao Castle, also known as Masuda Castle. Following the Battle of Sekigahara, the gate was moved to the temple grounds, and it was later rebuilt during the Edo period as a distinctive two-story temple gate.
The gate is characterized by its massive pillars and imposing two-tiered roof. Its powerful appearance gives visitors an immediate sense of the area’s samurai heritage. The gate is also designated as a Shimane Prefectural Tangible Cultural Property.
Another notable structure within the grounds is the Ichibei Gate. According to a local story, the gate was rebuilt through the extraordinary efforts of a temple servant named Ichibei.
Ichibei is said to have saved money through years of careful frugality until he had accumulated enough funds to rebuild the gate. A small statue known as the Ichibei Jizō is enshrined nearby in remembrance of his dedication.
Iko-ji also preserves a number of valuable Buddhist artworks dating from the Nanboku-chō and Muromachi periods. Among them are statues of Nikkō Bosatsu and Gakkō Bosatsu, as well as figures representing the Sixteen Arhats, revered Buddhist disciples.
The temple also houses traditional artworks and craft objects, including incense containers. Together, these treasures demonstrate the temple’s importance as a place where religious history, art, and craftsmanship have been preserved over the centuries.
Iko-ji is more than a historic temple. It also serves as a place for sharing and experiencing local culture. Visitors may enjoy matcha green tea on the temple grounds, offering a simple way to appreciate Japanese tea culture in a tranquil setting.
The temple is also used by local schools as a place for learning about regional history and culture. Through these activities, the heritage of Iko-ji continues to be passed on to younger generations.
Iko-ji is also one of the constituent cultural properties of the Japan Heritage story “Masuda: A Medieval Masterpiece — Rediscovering the Brilliance of a Regional Age”. Its history and cultural significance form an important part of the story of medieval Masuda.
Iko-ji offers a quiet atmosphere where visitors can experience traditional Japanese culture surrounded by nature. The Sesshū-associated garden is the temple’s greatest attraction, but the historic gates, Buddhist statues, temple treasures, and stories passed down through generations add further depth to a visit.
The temple is especially appealing to travelers interested in Japanese gardens, Zen Buddhism, samurai history, traditional architecture, and Japanese art. Even visitors simply looking for a peaceful place away from the bustle of modern life can enjoy the serene atmosphere of the grounds.
Iko-ji is approximately 10 minutes by bus from JR Masuda Station, making it a convenient stop when exploring Masuda City and the wider Iwami region.
With its centuries of history and beautifully designed landscape, Iko-ji Temple offers a memorable glimpse into the cultural heritage of Masuda. A visit here combines the quiet atmosphere of a Zen temple with the artistic beauty of a traditional Japanese garden and the historical legacy of the medieval Masuda region.
