Overview
Shōka (正嘉) is a Japanese era name (nengō) that covered the period from March 1257 until March 1259. Era names were used in Japan to mark and count years during an emperor's reign. Shōka followed the Kōgen era and preceded the Shōgen era. The reigning sovereign during Shōka was Emperor Go-Fukakusa (後深草天皇).
Name and dating
The characters 正 (shō) and 嘉 (ka) are conventionally read as "correct/just" and "auspicious/praiseworthy," respectively, so the compound evokes a wish for orderly and favorable times. The era began in March 1257 and ended in March 1259; historians therefore place Shōka within the broader mid-13th century chronology of the Kamakura period.
Political context
Although an imperial era name was set by the court, political authority in this period was largely exercised by the Kamakura shogunate and its regents. The imperial court at Kyoto continued to manage ceremonial and cultural affairs while real power over military and administrative matters rested with the bakufu. Shōka forms part of that dual-structure era in which court ritual and samurai governance coexisted.
Characteristics and calendar use
Like other nengō, Shōka served both practical and symbolic purposes: it provided a system for dating documents and events, and it expressed the court's hope for renewal or stability after specific incidents. Changes of era could be prompted by natural disasters, epidemics, auspicious signs, or political considerations; the court's proclamation fixed the new name and the start date.

Shōka is a brief interval in the long sequence of Japanese nengō, of interest mainly for chronological and documentary work. Researchers tracing court records, temple chronicles, or dated artifacts use era names like Shōka to synchronize events with the Gregorian calendar.
