Kakei (Japanese era name, 1387–1389)

Political background

The Nanboku-chō era was defined by the existence of two rival imperial lines. The Northern Court, centered in Kyoto and backed by the Ashikaga shogunate, used era names such as Kakei. Opposing it was the Southern Court, based at Yoshino. The Kakei era followed the Shitoku era name and preceded the Kōō era in the Northern Court sequence.

Rulers and claims

During Kakei the Northern Court recognized Emperor Go-Komatsu as sovereign, though contemporary and later historians often describe him as a pretender from the perspective of the Southern Court. The Southern Court continued to assert its own line of legitimate emperors and maintained separate era names and calendars. This rivalry shaped administration, ceremonial life, and the historical record of the late 14th century.

Characteristics and events

Kakei was a brief era of roughly a year and a half. Like many short nengō, it did not become associated with a major set of reforms or a single defining event; instead it sat within a prolonged era of military and political negotiation between court factions and the shogunate. The Ashikaga shogunate's influence in the north affected the choice and use of era names during this period.

Legacy and historical perspective

The Kakei era is most significant as a marker of the divided imperial chronology of the Nanboku-chō era. Modern scholarship and official determinations in later centuries have debated the relative legitimacy of the two courts; nevertheless, era names like Kakei remain useful identifiers for historians reconstructing chronology and political alignment in late medieval Japan.
