Saimyoji Main Hall: Japan's Very First Designated National Treasure
Nestled on a forested hillside at the foot of the Suzuka Mountains in Shiga Prefecture, Saimyoji Temple (西明寺) is one of Japan's most remarkable examples of Kamakura-period Buddhist architecture. The temple's Main Hall (本堂, Hondō) holds the extraordinary distinction of being one of the very first buildings designated as a National Treasure under Japan's original cultural preservation law of 1897. Together with its equally celebrated three-story pagoda, Saimyoji offers visitors a rare, immersive journey into medieval Japan — far from the tourist crowds of nearby Kyoto.
As part of the Koto Sanzan (湖東三山), the celebrated trio of Tendai Buddhist temples in eastern Shiga, Saimyoji was even selected by CNN as one of "Japan's most beautiful places." Yet it remains a hidden gem, offering an atmosphere of profound tranquility that more famous temples can no longer provide.
A History Stretching Back Over a Thousand Years
Saimyoji was founded in 834 (Jōwa 1) by the monk Sanshū Shōnin at the imperial command of Emperor Ninmyō. Established as a Tendai sect temple under the mountain name Ryūōzan (龍應山), it grew into a major center of Buddhist learning and practice. By the Kamakura period (1185–1333), the temple had expanded to include 17 halls and some 300 monks' quarters, making it one of the region's most influential religious institutions.
The temple's history took a dramatic turn during the Sengoku period when the warlord Oda Nobunaga launched his devastating campaign against Tendai Buddhist institutions. After burning Mount Hiei's Enryakuji in 1571, Nobunaga's forces turned their attention to the Koto Sanzan temples. While neighboring Hyakusaiji Temple was completely destroyed, the monks of Saimyoji managed to save the Main Hall, three-story pagoda, and Nitenmon Gate from the flames — a feat of courage that preserved these irreplaceable medieval structures for future generations.
In the Edo period, prominent Tendai monks including Tenkai and Kōkai, along with the lay patron Mochizuki Tomoaki, led efforts to restore the temple. The nationally designated scenic garden Hōraitei was created in 1673 to commemorate this revival.
Why the Main Hall Is Designated a National Treasure
The Main Hall of Saimyoji was constructed in the early Kamakura period, believed to be the work of master carpenters from the Hida region. It is a purely Japanese-style (wayō) building of exceptional craftsmanship, assembled entirely without the use of nails. The structure measures seven bays by seven bays (approximately 160 square meters) with an irimoya-style (hipped-gabled) roof covered in hinoki cypress bark shingles (hiwadabuki).
Architecturally, the Main Hall preserves quintessential Kamakura-period design elements, including elegant kaerumata (frog-leg struts) and refined lattice patterns that demonstrate the aesthetic sensibilities of the era. The building's state of preservation is remarkable — it retains its original medieval character to a degree rarely found in Japanese temple architecture.
On December 28, 1897, just six months after the promulgation of Japan's Ancient Temples and Shrines Preservation Law, the Saimyoji Main Hall received its National Treasure designation — making it one of the very first buildings in Japan to receive this honor. This designation was reconfirmed in 1952 under the modern Law for the Protection of Cultural Properties.
In 2020, an infrared survey conducted by researchers from Hiroshima University revealed an astonishing discovery: four Bodhisattva figures painted on the columns in front of the principal Buddhist image. Analysis suggests these paintings date to the latter half of the 7th century (Asuka period), making them among the oldest Buddhist paintings in Japan and suggesting the temple site may have an even longer history than traditionally believed.
Highlights and Treasures to See
The Main Hall Interior
The Main Hall enshrines a Heian-period standing statue of Yakushi Nyōrai (the Medicine Buddha) as its principal image, designated as an Important Cultural Property. Surrounding this central figure are Kamakura-period wooden sculptures of the Twelve Heavenly Generals (Jūni Shinshō), each bearing a different zodiac animal on his head. Additional Important Cultural Properties housed within include a Kamakura-period Shaka Nyōrai statue in the Seiryōji style, Heian-period statues of Fudō Myōō (Acala) with two attendants, and the Two Heavenly Kings (Kōmoku-ten and Tamon-ten).
During special viewing periods (typically late March through early April and June through September), visitors can see the rear sanctum's remarkable collection of Buddhist statues, including the Amida Triad, a Benzaiten figure, and Muromachi-period terracotta figures of the monks Ryōgen and Shinran.
The Three-Story Pagoda (National Treasure)
Standing 24 meters tall beside the Main Hall, this all-cypress pagoda was built during the mid-Kamakura period, also by Hida craftsmen using no nails. Its first-floor interior features stunning polychrome murals painted by artists of the Kose school — the only surviving Kamakura-period temple murals in Japan. These vividly colored paintings depict scenes from the Lotus Sutra, Dainichi Nyōrai with 32 attendant Bodhisattvas, and hōsōge (imaginary flowers), all rendered in mineral pigments of extraordinary purity. Special admission is required for viewing.
Nitenmon Gate (Important Cultural Property)
This eight-legged gate dates from the early Muromachi period (1407) and features a kokera-buki (thin wooden shingle) roof. It serves as the dramatic entrance to the temple's inner precinct.
Hōraitei Garden (National Scenic Site)
This Edo-period pond garden was designed in 1673 to represent the Buddhist Pure Land. Stone arrangements symbolize Yakushi Nyōrai and the Twelve Heavenly Generals, while the heart-shaped pond contains crane and turtle islands — traditional symbols of longevity. It is ranked among Japan's 50 finest gardens.
Fudan-zakura and Meoto-sugi
The temple grounds feature a remarkable "ever-blooming cherry" (Fudan-zakura) that flowers in autumn, winter, and spring — designated a Shiga Prefecture Natural Monument at an estimated 250 years of age. The Meoto-sugi (Husband and Wife Cedars) are a pair of ancient Japanese cedars reputed to be over 1,000 years old.
The Pilgrimage Trail and Surrounding Area
The approach to Saimyoji is itself an experience not to be missed. Moss-covered stone steps wind uphill beneath a canopy of over 1,000 maple trees, passing the remnants of old monks' quarters marked by Anō-zumi stone walls — a traditional masonry technique. The atmosphere along this path is one of timeless serenity, especially beautiful during the autumn foliage season when the entire mountainside blazes with color.
Saimyoji is the 32nd stop on the Saigoku Yakushi 49 Temple Pilgrimage, a route established in 1989 connecting sacred sites dedicated to the Medicine Buddha across the Kansai region, from Yakushiji in Nara to Enryakuji in Kyoto.
Visitors are encouraged to explore the other two Koto Sanzan temples as well. Kongōrinji Temple, about 2.5 km south, houses its own National Treasure main hall and over 2,000 colorfully dressed Jizo statues. Hyakusaiji Temple, further south, is one of Japan's oldest temples, with a deeply atmospheric mountain setting. During the November autumn foliage season, convenient shuttle buses run between Hikone Station and all three temples.
The nearby city of Hikone offers the National Treasure Hikone Castle, one of only five original castle keeps in Japan, as well as the charming Edo-period streetscape of Yonbancho Square. Lake Biwa, Japan's largest lake, is just 11 km to the west.

Q＆A
- Is English guidance available at Saimyoji Temple?
- The temple has information sheets available in English at the reception desk. Signage is primarily in Japanese, but the architectural beauty and atmosphere can be fully appreciated without language support. Consider downloading a translation app or bringing a guidebook for deeper understanding of the Buddhist statuary.
- When is the best time to visit Saimyoji Temple?
- Autumn (mid-November) offers the most spectacular scenery, when the 1,000+ maple trees turn brilliant shades of red and gold. However, the fresh green maple season (May–June) is equally beautiful and far less crowded. The special viewing of the rear sanctum Buddhist statues is available from late March to early April and June through September. The ever-blooming cherry tree flowers in autumn and winter, offering a unique sight.
- How do I get to Saimyoji Temple without a car?
- From JR Kawase Station on the Biwako Line, take a bus toward Ōmi Railway Amago Station and alight at the nearest stop (approximately 15 minutes). During the November foliage season, the Koto Sanzan Shuttle Bus operates between JR Hikone Station and all three temples. Outside peak season, a taxi from Hikone or Amago Station is the most convenient option. Rental bicycles are also available at some Ōmi Railway stations.
- Can I see the murals inside the three-story pagoda?
- The Kamakura-period polychrome murals inside the pagoda's first floor are available for viewing during special exhibition periods, which require a separate admission fee in addition to the regular entrance fee. Please contact the temple directly at +81-749-38-4008 for current viewing schedules and fees.
- Is the temple accessible for visitors with mobility limitations?
- The main approach involves a long climb up stone steps, which may be difficult for those with mobility challenges. However, there is an alternative vehicle access route to a parking area near the garden and temple buildings, which reduces the amount of walking required. Wheelchair-accessible parking is available. Contact the temple in advance to arrange the most suitable route.
