Jōgen

Overview

Jōgen (承元) was a Japanese era name, or nengō (年号, "year name"), that followed Ken'ei and preceded Kenryaku. The era spanned from October 1207 through March 1211, during the Kamakura period (1185–1333). The reigning emperors during this time were Tsuchimikado-tennō (土御門天皇) and Juntoku-tennō (順徳天皇).

The era began in the tenth month of 1207, when the court proclaimed a new nengō to mark a fresh chapter in the imperial calendar. It ended in the third month of 1211, when the name was changed again to Kenryaku. The Jōgen era thus lasted roughly three and a half years, a relatively short span typical of medieval Japanese era names, which were often changed to signal political shifts or to seek divine favour.

What Defined the Era

The Jōgen era unfolded against the backdrop of the Kamakura shogunate, the military government established in eastern Japan in 1185. While the emperor in Kyoto retained ceremonial and religious authority, real political power lay with the shogun and the warrior class in Kamakura. The era name itself was chosen by the imperial court, but the shogunate's influence pervaded court decisions, including the selection of era names.

The era is notable for the transition between two emperors. Emperor Tsuchimikado reigned at the start of Jōgen, but in 1210 he abdicated, and his younger brother Juntoku ascended the throne. This succession occurred within the era's span, making the change of sovereigns a defining feature of the period. The abdication was part of the complex dynastic politics of the time, where retired emperors and competing factions within the imperial family vied for influence.

The Kamakura period as a whole was marked by the consolidation of warrior rule, the development of feudal institutions, and the spread of Buddhism among the common people. The Jōgen era, though brief, sat within this broader transformation, with the court and the shogunate navigating their uneasy coexistence.

Key Events

The most significant event of the Jōgen era was the imperial succession. In 1210, Emperor Tsuchimikado abdicated, and Emperor Juntoku took the throne. Juntoku would later play a central role in the Jōkyū War of 1221, an attempted rebellion against the Kamakura shogunate that ended in defeat and the exile of the emperor. The seeds of that conflict were already present during Jōgen, as tensions between the court and the shogunate simmered beneath the surface.

Beyond the succession, the era saw the continuation of religious and cultural activities typical of the period. Buddhist temples and shrines received imperial patronage, and the court engaged in the customary rituals and ceremonies that marked the passage of time. No major military campaigns or natural disasters are recorded as defining the Jōgen era, and its historical significance rests primarily on the political transition it contained.

The era also witnessed the ongoing development of the nengō system itself, which had been in use since the seventh century. Each new era name was proclaimed with formal ceremonies, and the choice of characters was meant to convey auspicious meanings. The Jōgen era was no exception, with its name reflecting the court's hopes for the years ahead.

The Name in Japanese

The Japanese name for this era is 承元, read in kana as じょうげん and in romaji as Jōgen.

The name consists of two kanji:

• 承 (じょう, jō): This character means "to receive," "to accept," or "to inherit." It carries the sense of taking on something handed down, whether a tradition, a mandate, or a responsibility. In the context of an era name, it suggests the acceptance of heaven's will or the continuation of imperial authority.

• 元 (げん, gen): This character means "origin," "beginning," or "foundation." It is a common element in era names, appearing in many nengō across Japanese history. It conveys the idea of a new start, a root from which things grow, or the fundamental basis of a reign.

Together, 承元 can be understood as "receiving the origin" or "accepting the foundation." The name evokes the idea of the emperor and the court inheriting the mandate to rule and establishing a fresh beginning under that mandate. The choice of these characters reflects the ritual importance of era names as declarations of renewal and continuity.

In Japanese, the era name is written with the kanji 承元, and when referring to years within the era, one would say, for example, Jōgen ninen (承元二年), meaning "the second year of Jōgen." The reading じょうげん is the standard on-yomi, or Chinese-derived reading, of both characters.

How the Era Name Works

The Japanese era name system, known as nengō (年号), is a method of counting years based on the reign of an emperor or a proclaimed era. The system was adopted from China in the seventh century, with the first Japanese era name proclaimed in 645 during the Taika Reform. Since then, era names have been used to mark time, with each name typically lasting for a few years to several decades.

An era name is proclaimed by the imperial court, often to commemorate a significant event, such as an emperor's accession, a natural disaster, or a hoped-for auspicious change. The name is chosen from classical Chinese texts, and the characters are selected for their positive connotations. Once proclaimed, the era name remains in effect until it is changed, at which point a new name is announced and the calendar resets to year one.

During the Kamakura period, era names were changed relatively frequently, sometimes after only a few years. The Jōgen era, lasting from 1207 to 1211, was typical in this regard. The change from Ken'ei to Jōgen in 1207 and from Jōgen to Kenryaku in 1211 were both imperial proclamations, reflecting the court's ongoing practice of renewing the calendar.

The nengō system continued in use until 1868, when the Meiji government adopted the practice of a single era name for the entire reign of an emperor. Since then, each emperor has had one era name, and the system remains in use today, with the current era, Reiwa, having begun in 2019. For students of Japanese, understanding era names is essential for reading historical documents, as dates are often given in terms of the era year rather than the Western calendar.
