光格天皇
Two more eras would follow during Kōkaku's reign, on 5 February 1801 a new era name (Kyōwa) was created because of the belief that the 58th year of every cycle of the Chinese zodiac brings great changes. Three years later the new era name of Bunka (meaning "Culture" or "Civilization") was created to mark the start of a new 60-year cycle of the Heavenly Stem and Earthly Branch system of the Chinese calendar which was on New Year's Day. During this year, Daigaku-no-kami Hayashi Jussai (1768–1841) explained the shogunate foreign policy to Emperor Kōkaku in Kyoto. The rest of Kōkaku's reign was quiet aside from two 6.6m earthquakes which struck Honshū in the years 1810 and 1812. The effects on the population from these earthquakes (if any) is unknown.
