Chojuji Temple Main Hall

Chojuji Temple Main Hall: A National Treasure of Pure Japanese Architecture

Nestled at the northeastern foot of Mount Aboshi in the city of Konan, Shiga Prefecture, Chojuji Temple (長寿寺) is a Tendai Buddhist temple with over 1,200 years of history. Its Main Hall (Hondo) stands as one of Japan's designated National Treasures — a masterpiece of early Kamakura-period pure Japanese (wayo) architecture that has quietly endured the centuries. Known locally as "Higashi-dera" (East Temple) in contrast to neighboring Jorakuji's "Nishi-dera" (West Temple), Chojuji is one of the celebrated Konan Sanzan — a trio of ancient Tendai temples in Konan City, each boasting National Treasure structures of extraordinary historical significance.

The Founding Legend of Chojuji Temple

According to temple tradition, Chojuji was founded during the Tenpyo era (729–749) of the Nara period. Emperor Shomu, who had no heir, asked the eminent monk Roben to pray for the birth of a child. Roben retreated to Mount Aboshi for intensive prayer, and the emperor was eventually blessed with a princess — later known as Empress Koken. Overjoyed, Emperor Shomu ordered the construction of a grand temple complex with seven principal halls and twenty-four sub-temples, naming it "Chojuji" — meaning "Long Life Temple" — as a prayer for his daughter's longevity. The principal image, a statue of Koyasu Jizo (protector of children and safe childbirth), was reportedly carved by the great monk Gyoki and enshrined as the temple's main object of worship.

Throughout subsequent centuries, the temple received patronage from some of Japan's most powerful figures. Minamoto no Yoritomo, the first Kamakura shogun, designated it as a prayer temple in the early Kamakura period. The Ashikaga shoguns continued this patronage during the Muromachi period, and a directive (seisatsu) from Ashikaga Takauji is still preserved at the temple today. However, the Sengoku period brought upheaval: Oda Nobunaga relocated the temple's Three-Story Pagoda to Sokenji near Azuchi Castle, where it remains to this day. The temple's grand gate (Romon) was likewise moved to another temple in what is now Ritto City, though neither the gate nor that temple has survived.

Why the Main Hall Is Designated a National Treasure

The Main Hall of Chojuji was designated a National Treasure on March 31, 1953, having previously been recognized as an Important Cultural Property since 1898. Although its exact construction date is unknown due to lost records, architectural analysis places it in the late Heian period or early Kamakura period (late 12th to early 13th century).

The hall is celebrated as an outstanding example of pure wayo (Japanese-style) architecture from the early Kamakura period. Its designation recognizes not only the exceptional aesthetic quality of the design but also its remarkable preservation of archaic construction techniques, including the roof framing (koyagumi), which retains methods from an earlier era. The building is valued both as a work of art and as an invaluable document in the history of Japanese architectural technology.

One of the most distinctive features is the building's retention of the "narabido" (dual-hall) structural form — an early Buddhist hall configuration in which the inner sanctuary (naijin) and outer worship hall (gejin) were originally separate structures with independent roofs, later unified under a single cypress bark roof. This transitional form provides scholars with precious evidence of how Japanese temple architecture evolved from paired buildings into the integrated hall designs of later periods.

Architectural Highlights and Features

The Main Hall is a single-story structure measuring five bays by five bays, with a three-bay step canopy (kohai) projecting from the front. The roof is a graceful hip roof (yosemune-zukuri) covered in hinoki cypress bark shingles (hiwadabuki), giving it a low, elegant profile that harmonizes beautifully with the surrounding forest landscape.

The exterior features shitomido lattice shutters — a characteristic element of classical Japanese architecture that allows gentle light and air to filter into the interior. The kaerumata (frog-leg struts) found between the pillars display archaic decorative forms that may date the structure even earlier than the Kamakura period, possibly to the late Heian era.

Inside the hall, the nationally designated Kasuga-style miniature shrine (Kasuga-zushi) — itself listed as an accessory National Treasure — houses the temple's hidden principal image. Flanking the main image are statues of Kannon (Avalokitesvara) and Bishamonten (Vaisravana), though all are hibutsu (hidden Buddha images) that are only revealed to the public once every fifty years. The interior also houses several Important Cultural Properties, including Buddhist statues from various periods. Behind the Main Hall, a modern storage building (shuzoko) contains a magnificent Joroku Amida Nyorai — a seated golden Amida Buddha statue approximately three meters tall that is a truly awe-inspiring sight.

Seasonal Beauty and Atmosphere

The approximately 100-meter approach path from the temple gate to the Main Hall is one of Chojuji's most beloved features. Lined with maple trees and towering cedar trees that have stood for centuries, the path transforms dramatically with the seasons. In spring, fresh green maple leaves create a luminous canopy overhead. Summer brings deep, cool shade beneath the dense foliage. Autumn is perhaps the most spectacular season, when the maples blaze with crimson and gold, forming a breathtaking tunnel of color that draws visitors from across the region.

Each year from mid-November to early December, the Konan Sanzan Autumn Foliage Tour (Konan Sanzan Momiji Meguri) connects all three temples in a special seasonal event, with shuttle buses running between the temples and local train stations. The quiet, rural setting of Chojuji — far from the crowds of Kyoto's famous temples — offers a truly intimate experience with Japan's autumn beauty.

Other Cultural Properties on the Grounds

Beyond the National Treasure Main Hall, Chojuji's grounds contain several other important structures. The Benten-do Hall, dating from 1550 during the Muromachi period, is designated as an Important Cultural Property. Adjacent to the temple stands Hakusan Shrine, whose worship hall (haiden) is also recognized as an Important Cultural Property. A stone multi-story pagoda (sekizo tahoto) along the approach path adds another layer of historical interest to the grounds.

Visitors entering the Main Hall — which is freely accessible during opening hours — can appreciate the solemn atmosphere of the interior, though photography inside is not permitted. The overall experience is one of quiet contemplation, surrounded by centuries of history and devotion.

Nearby Attractions

Chojuji is ideally positioned for exploring the broader cultural heritage of Konan City. The two companion temples of the Konan Sanzan are within easy reach: Jorakuji Temple, known as "Nishi-dera" (West Temple), is just a 15-minute walk downhill and boasts two National Treasures — its Main Hall and Three-Story Pagoda. Zensuiji Temple, accessible by train from Kosei Station, houses an impressive Main Hall (also a National Treasure) containing numerous Important Cultural Property Buddhist statues.

For those interested in Edo-period history, Ishibe-juku — the 51st post station on the historic Tokaido road — is nearby. The Ishibe Shukuba no Sato recreates the atmosphere of this old post town with restored farmhouses, merchant shops, and inns. Juraku no Sato, located just a minute's walk from Chojuji, is a family-friendly park offering pottery workshops, woodcraft experiences, walking paths, and the natural hot spring facility Junibo Onsen Yurara near Zensuiji Temple.
