Ryosenji Temple is the head temple of the Ryosenji Shingon Buddhist sect, located in Naka-machi, Nara City, Nara Prefecture. It is also known by the mountain names Tomisan and Bikozan. The temple’s principal object of worship is Yakushi Nyorai, the Buddha of Medicine, who is revered for healing illness and bringing peace to body and mind. The temple is traditionally associated with two eminent Buddhist monks: Gyoki, who lived during the Nara period, and Bodhisena, a Buddhist monk who came to Japan from India.
The temple’s standard Japanese reading is “Ryosenji,” although it is also pronounced “Ryozenji” or “Reizanji.” All three names are familiar locally. Situated among the gentle hills along the Tomio River, west of central Nara, the temple escaped much of the destruction caused by warfare. As a result, it preserves an unusually rich atmosphere of ancient and medieval Japan.
According to temple tradition, Ryosenji’s origins date back to the Asuka period (538–710). Ono Tomito, said to have been the son of the diplomat Ono no Imoko, resigned from official service after the Jinshin War and withdrew to Mount Tomi. In 684, during a pilgrimage to Kumano, he is said to have experienced the miraculous power of Yakushi Nyorai. Following a divine revelation, he enshrined a triad of Yakushi Buddha and attendant bodhisattvas on the mountain, cultivated medicinal herbs, and prepared therapeutic baths to help those suffering from illness. He subsequently became known as Tomi Sennin or Bikō Sennin, meaning the Hermit of Tomi or the Hermit with the Prominent Nose.
In 728, Princess Abe, daughter of Emperor Shomu and the future Empress Koken, fell seriously ill. According to tradition, Bikō Sennin appeared in the emperor’s dream and revealed the healing power of the Yakushi Buddha enshrined on Mount Tomi. Gyoki then performed prayers at the site, and the princess recovered. In 734, Emperor Shomu ordered Gyoki to build a large temple hall on Mount Tomi, beginning Ryosenji’s development as a temple dedicated to prayers for the welfare of the state.
In 736, Bodhisena, an Indian Brahmin monk who had arrived in Japan, is said to have recognized a resemblance between the landscape of Mount Tomi and India’s sacred Vulture Peak, known in Japanese as Ryojusen. He therefore named the temple Ryosenji. Emperor Shomu reportedly bestowed a temple plaque bearing the name “Bikō Ryosenji,” establishing the name by which the temple became known.
During the Heian period (794–1185), the renowned monk Kukai, also known as Kobo Daishi, is said to have visited Ryosenji and encountered a dragon deity on Mount Tomi. Following this event, the temple’s Okunoin inner sanctuary came to enshrine Dai Benzaiten Nyozon, a revered form of Benzaiten associated with wisdom, eloquence, and good fortune.
Although Ryosenji was associated with the Hosso school of Buddhism, it also incorporated elements of Shingon esoteric Buddhism, developing a distinctive tradition that embraced both schools.
During the Kamakura period (1185–1333), the temple flourished, with as many as 21 monastic residences. Important structures, including the Main Hall and Three-Story Pagoda that survive today, date from this period. The fact that the temple escaped major destruction in warfare has helped preserve its historic architecture and Buddhist sculptures in remarkably good condition.
In the Edo period (1603–1868), Ryosenji maintained its standing as a temple receiving official patronage from the shogunate. It declined for a time following the anti-Buddhist movement of the Meiji period. In 1951, it became independent and adopted the name Ryosenji Shingon Buddhism, which it continues to use today.
The most celebrated building at Ryosenji is its Main Hall, designated a National Treasure. The hall has an irimoya-style roof, combining a gabled and hipped structure, covered with traditional Japanese roof tiles. An inscription on its ridge plaque confirms that it was built in 1283, making it an outstanding example of the Japanese architectural style used for Buddhist halls during the Kamakura period.
The sanctuary inside the hall also dates from the same period. It houses the temple’s principal image, a secret Buddhist triad centered on Yakushi Nyorai, designated an Important Cultural Property.
The triad was created in 1066 and features a flat halo characteristic of Buddhist sculpture from the Nara region. As a hidden image, it is normally not on public display. Special viewings take place during the annual Autumn Roses and Sacred Treasures Exhibition and during the New Year’s Shusho-e ceremonies held over the first three days of January. These occasions draw many worshippers and visitors.
On the southern slope across the valley stands the Three-Story Pagoda, also designated an Important Cultural Property. Approximately 17 meters tall, it has a graceful roof covered with cypress bark shingles. Its first-floor interior contains richly colored murals depicting the Five Wisdom Kings and the Buddha’s Parinirvana, or final passing into nirvana. The excellent preservation of these paintings adds considerably to the pagoda’s historical and artistic importance.
Since the modern era, worship of Dai Benzaiten Nyozon has become a major focus of religious activity at Ryosenji. The Dai Benzaiten-do Hall was built in 1935. In 1960, the Golden Hall, whose interior and exterior are covered in gold leaf, was completed. In 1977, the Platinum Hall, featuring platinum leaf, followed.
These striking buildings create a distinctive landscape in which modern religious architecture stands alongside the temple’s ancient halls and pagoda. Their presence adds another dimension to Ryosenji’s long history of Buddhist worship.
Ryosenji is widely known as a “Temple of Flowers,” particularly for its celebrated rose garden. Established in 1957 with the hope of promoting world peace, the garden bursts into bloom in spring and autumn, displaying approximately 2,000 rose bushes representing around 200 varieties.
The vivid colors and fragrances of the roses form a beautiful contrast with the temple’s venerable halls and traditional Buddhist architecture. This combination of historic serenity and seasonal floral beauty offers visitors a memorable sense of peace and inspiration.
Ryosenji brings together several dimensions of Japanese heritage: a religious tradition dating back to the Nara period, architecture and Buddhist sculptures of exceptional cultural value, the worship of Benzaiten, and a modern rose garden that has become one of its defining attractions.
Set in the peaceful western outskirts of Nara, the temple offers an opportunity to experience history, nature, prayer, and beauty in one place. Whether visiting Nara for the first time or returning to explore its lesser-known treasures, travelers will find Ryosenji a rewarding destination where the heritage of ancient Japan continues to inspire.
