Events of Ieharu's reign Tenmei gannen (天明元年) or Tenmei 1 (1781): The new era name of Tenmei (meaning "Dawn") was created to mark the enthronement of Emperor Kōkaku. The previous era ended and the new one commenced in An'ei 11, on the 2nd day of the 4th month. According to Nihon Ōdai Ichiran, Ieharu was appointed Udaijin (Minister of the Right) of the Emperor's Kugyō, which was quite rare and considered a great favour. Tenmei 2 (1782): Great Tenmei Famine begins. Tenmei 2 (1782): An analysis of silver currency in China and Japan "Sin sen sen pou (Sin tchuan phou)" was presented to the emperor by Kutsuki Masatsuna (1750–1802), also known as Kutsuki Oki-no kami Minamoto-no Masatsuna, hereditary daimyō of Oki and Ōmi with holdings in Tanba and Fukuchiyama -- related note at Tenmei 7 below. Tenmei 3 (1783): Mount Asama (浅間山, Asama-yama) erupted in Shinano, one of the old provinces of Japan (Tenmei eruption). Isaac Titsingh's published account of the Asama-yama eruption (1820) was the first of its kind in the West. The volcano's devastation makes the Great Tenmei Famine even worse. Tenmei 4 (1784): Country-wide celebrations in honor of Kūkai (also known as Kōbō-Daishi, founder of Shingon Buddhism) who died 950 years earlier. Tenmei 6, on the 8th day of the 9th month (17 September 1786): Death of Tokugawa Ieharu. He is buried in Edo. – see online image of 2 adjacent pages from library collection of Kyoto University of Foreign Studies and Kyoto Junior College of Foreign Languages
