Emperor Seiwa

was the 56th emperor of Japan, according to the traditional order of succession. Seiwa's reign spanned the years from 858 through 876. He was the ancestor of the Seiwa Genji, who later became the leaders of the warrior class.

Before his ascension to the Chrysanthemum Throne, his personal name (his imina) was , the first member of the Imperial house to be personally named "-hito" . One meaning of the character 仁 is the Confucian concept of ren. Later it has been a tradition to name the personal name of all male members of the Imperial family this way. He was also known as emperor as Mizunoo-no-mikado or Minoo-tei.

Biography

Emperor Seiwa was born four days after his father, Emperor Montoku, ascended the throne. He was the fourth son, following his half-brothers, Princes Korechika, Korejo, and Korehiko. However, under the influence of his maternal grandfather, Fujiwara no Yoshifusa, and against the wishes of his father, he displaced his older siblings and was proclaimed Crown Prince at the age of eight months. In 858, upon the death of Emperor Montoku, he ascended to the throne at the age of nine. The ailing Emperor Montoku attempted to have Prince Korechika, six years his senior, succeed to the throne as a temporary successor, but this did not materialize. Due to his young age, Fujiwara no Yoshifusa held all political power as regent.

In 866, the Ōtenmon Incident occurred, centered on the destruction of the main gate (Ōtenmon) of the of the Imperial Palace. Per the Nihon Sandai Jitsuroku, Fujiwara no Yoshifusa was able to use this incident to purge all of his political rivals and secure the formal title of Sesshō.

In 876, Emperor Seiwa abdicated in favor of his eldest son, the 9-year-old Prince Sadaakira (Emperor Yōzei), and became a retired emperor. Two and a half years later, in May 879, he became a monk, and from October of that year, he began a pilgrimage around the Kinai region. In March of the following year, he entered Mizuo in Tanba Province and undertook intense ascetic practices involving fasting. He established Mizuo as his place of seclusion and, while constructing a new temple, fell ill at the Seikakan, the villa of Minister of the Left Minamoto no Tōru. He was moved to Engaku-ji in Awata and later passed away. He was 31 years old.

Grave of Emperor Seiwa

Emperor Seiwa relocated due to illness to the Awata-in villa (which later became the temple of Engaku-ji) and was cremated at Kami-Awatayama in Rakuto (eastern Kyoto) on the hill behind Konkaikōmyō-ji, and buried in Mizuo in Ukyō-ku, Kyoto according to his wishes. His tomb is designated by the Imperial Household Agency as the or Seiwa Tennō Ryō. From the site of his tomb the Emperor Seiwa is sometimes referred to as the . It is one of the Heian period imperial tombs whose location is almost certainly confirmed; however, per the emperor's wishes, it was only a simple burial with no mausoleum and was not listed in the Engishiki's listing of imperial mausoleums. During the Edo period, the current site was repaired during the Bunkyu Restoration of Imperial Mausoleums in 1862-1863, at which time the current circular mound with a gate and moat were constructed.

The kami of Emperor Seiwa is venerated at the Seiwatennō-sha, a Shinto shrine near the mausoleum.

Events of Seiwa's life

Originally under the guardianship of his maternal grandfather Fujiwara no Yoshifusa, he displaced Imperial Prince Koretaka (惟喬親王) as Crown Prince. Upon the death of his father in 858, Emperor Montoku, he became Emperor at the age of 9, but the real power was held by his grandfather, Yoshifusa.
