Kyōroku (享禄): Japanese era name, August 1528–July 1532

Overview and context

The era system (known as nengō) assigns names to stretches of years and was normally revised to mark significant events, auspicious omens, or administrative decisions. Kyōroku succeeded the Daiei era and was followed by the Tenbun era. Because the Japanese calendar in this period was lunisolar, the named years of Kyōroku overlap parts of Western calendar years.

Kyōroku belongs to the wider backdrop of the Sengoku (Warring States) era, when central authority was weak and regional warlords (daimyō) contested power. While the imperial court continued under Go‑Nara, the Ashikaga shogunate still existed in name and regional politics were defined by shifting alliances, military campaigns and local administration rather than by sustained national reform.

Characteristics and usage

• Dates: Kyōroku began in August 1528 and ended in July 1532 (commonly enumerated as Kyōroku 1–5).
• Primary uses: dating of official documents, religious texts, temple records, inscriptions and private diaries.
• Cultural role: era names appear on seals, commemorative works and later historical accounts to situate events in time.

For historians and archivists, Kyōroku provides a compact chronological window useful for dating manuscripts, land records and temple chronicles. Converting Kyōroku dates to modern Gregorian equivalents requires attention to the lunisolar months and occasional intercalary months used in premodern Japan.
