The Buddha who vowed to create a pure land in the east called the “Jōruri World” in order to save those suffering from illness — that is Yakushi Nyorai (Bhaiṣajyaguru). Among the most ancient Nyorai venerated in Japanese Buddhism, the court already worshipped this Buddha deeply for national protection and healing of illness during the Nara-Asuka period. This is a living Buddha that people still visit to pray for good health.

What is Yakushi Nyorai: The Master of Medicine and the Twelve Great Vows
The Vows of Bhaiṣajyaguru, “Master of Medicine”
The Sanskrit name for Yakushi Nyorai is Bhaiṣajyaguru, meaning “Master of Medicine.” The Chinese translation “Yakushi Ruri-ko Nyorai” (Medicine Buddha of Lapis Lazuli Light) conveys the meaning of illuminating illness and suffering with light as pure and brilliant as lapis lazuli.
Before attaining Buddhahood, when still practicing as a Bodhisattva, Yakushi Nyorai made twelve great vows. Three are particularly important:
Vow
Content
6th Vow “Completeness of Faculties”
Make complete the bodies of those with disabilities of eyes, ears, and limbs
7th Vow “Peace of Body and Mind”
Those suffering from illness who call Yakushi’s name will be cured
12th Vow “Sufficiency of Clothing and Food”
Enrich those suffering poverty without clothing and food
These vows made Yakushi Nyorai a special presence as a Buddha of genze-riyaku (this-worldly benefits) — not salvation after death but “saving from suffering in this world, right now.” When Empress Komyo established the Seyakuin medical dispensary in the Nara period to provide medicine to the poor, this was also an act of compassion based on Yakushi faith.

Identifying Yakushi Nyorai: The Medicine Jar, Semui-in, and Flanking Bodhisattvas
The Left-Hand Medicine Jar as the Primary Identifier
The most important feature for identifying Yakushi Nyorai as a Buddhist statue is the yakubo (medicine jar) held in the left hand. This jar contains medicine for curing illness, and it is an attribute unique to Yakushi Nyorai not found on other Nyorai statues.
For the hand gesture (mudra), the most common arrangement is Yakushi extending the right hand forward with fingers raised in the semui-in (abhaya mudra) — the mudra that declares “fear not” — while the left hand holds the medicine jar. However, mudras vary by period and sect.
The Yakushi Triad Formation
Yakushi Nyorai is sometimes enshrined alone, but in most cases is placed in the “Yakushi Sanzon (Yakushi Triad)” form flanked by Nikko Bosatsu (Surya-Prabhasa) and Gakko Bosatsu (Candra-Prabhasa) on left and right. These two Bodhisattvas symbolizing the light of the sun and moon serve as attendants (wakiji) who deliver Yakushi’s light of compassion to sentient beings ceaselessly day and night.
The Yakushi Triad installed in the Kondo (main hall) of Yakushiji Temple in Nara dates to the late 7th-early 8th century and is designated a National Treasure. The central Yakushi Nyorai seated figure stands about 2.5 meters high. Its well-proportioned physique and peaceful expression is the pinnacle of Hakuho-period sculpture called “frozen music” — a benchmark work for understanding the form of Yakushi Buddhas.

The Twelve Divine Generals: Warrior Protectors of Yakushi’s Vows
Correspondence Between the Twelve Vows and the Twelve Generals
Inseparable from the faith in Yakushi Nyorai are the Juni Shinsho (Twelve Divine Generals). These are warrior deities each protecting one of Yakushi’s twelve great vows, corresponding to the twelve zodiac animals (rat, ox, tiger, rabbit, dragon, snake, horse, sheep, monkey, rooster, dog, boar).
Each general wears armor, bears the zodiac animal on its head, and stands with a wrathful expression. Those who venerate Yakushi Nyorai are protected day and night from all twelve directions by these twelve generals.
Among the finest examples of the Twelve Divine Generals are the clay statues at Shinyakushiji Temple in Nara. Eleven of the twelve generals created in the 8th century (Tempyo period) are Nara-period works, making them among the oldest surviving examples. The sight of life-size figures standing in a circle surrounding the central shrine in the main hall is overwhelming — masterpieces expressing in full the vow of protection for Yakushi Nyorai.
Additionally, the seated Yakushi Nyorai at Horyuji Temple (installed in the Golden Hall) is attributed to around 607 CE — an Asuka-period masterpiece. Its archaic smile and imposing physique conveys to this day the depth of Yakushi faith in Japan at the time of Buddhism’s earliest transmission.

Frequently Asked Questions
How can I distinguish Yakushi Nyorai from other Nyorai?
The most reliable method is to check “whether the left hand (to your right when facing the statue) holds a medicine jar.” The medicine jar is unique to Yakushi Nyorai and is not held by other Nyorai (Shakyamuni, Amida, Dainichi). Confirming it in combination with the right hand’s semui-in (abhaya mudra, palm raised facing forward) makes identification even more certain.
What are Nikko Bosatsu and Gakko Bosatsu, the attendants of Yakushi Nyorai?
Nikko Bosatsu (Surya-Prabhasa) and Gakko Bosatsu (Candra-Prabhasa) are the attendants that together with Yakushi Nyorai constitute the “Yakushi Sanzon (Yakushi Triad).” Symbolizing the light of the sun and moon respectively, they serve to deliver Yakushi Nyorai’s compassionate light to sentient beings ceaselessly day and night. Their appearance can be confirmed in the National Treasure Yakushi Triad at Yakushiji in Nara.
How can I find my own zodiac animal among the Twelve Divine Generals?
The Twelve Divine Generals correspond to the twelve zodiac signs, with each general bearing the zodiac animal on its head. Rat year → Kubira (Kumbhira), Ox year → Basara (Vajra), and so on for all twelve. At Shinyakushiji, where twelve figures stand encircling the main hall, it is easy to find your own protective general by the animal image on each figure’s head.
What is the difference between Yakushiji and Shinyakushiji?
Yakushiji is a large temple complex founded by Emperor Tenmu in the late 7th century, with the National Treasure Yakushi Triad (central Buddha) as the main attraction. Shinyakushiji, by contrast, is a relatively intimate temple founded at the vow of Emperor Shomu in the 8th century, with the National Treasure Twelve Divine Generals (life-size) surrounding the main hall as its overwhelming highlight. For seeing Yakushi Nyorai’s “full presence,” Yakushiji is recommended; for “spatial experience with the Twelve Divine Generals,” Shinyakushiji is by far the better choice.
Is there a most effective method of worship for Yakushi Nyorai?
The esoteric method is to face the principal image with palms pressed together, chanting Yakushi Nyorai’s mantra “On Korokoro Sendari Matoogi Sowaka” silently or softly. Formal worship typically involves three bows to the principal image followed by seven recitations of the mantra. However, “a sincere heart of prayer” is most important and there is no need to be too constrained by formalities.
