1704 Hōei gannen (宝永元年): In reaction to the Great Genroku earthquake in Genroku 16, the era name was changed to Hōei (meaning "Prosperous Eternity"). The previous era ended and the new one commenced in Genroku 17, on the 13th day of the 3rd month.
October 28, 1707 (Hōei 4, 4th day of the 10th month): Great Hōei earthquake. The city of Osaka suffers tremendously because of a very violent earthquake.
December 16, 1707 (Hōei 4, 23rd day of the 11th month): An eruption of Mt. Fuji; the cinders and ash fell like rain in Izu, Kai, Sagami, and Musashi.

February 19, 1709 (Hōei 6, 10th day of the 1st month): The wife of Shogun Tsunayoshi killed him with a knife, and then she stabbed herself in the heart. Tsunayoshi's homosexual interests were aroused by the son of the daimyō of Kai; and his plans to adopt this Tokugawa youth as his successor were known by a few inside Edo Castle. The shogun's wife, who was also a daughter of the emperor, foresaw that this choice of a successor would be very poorly received by many; and she feared that it might result in a disastrous civil war. The shogun's wife did everything she could to dissuade Tsunayoshi from continuing with such potentially divisive and dangerous plans; and when it became clear that her arguments were in vain, she resolutely sacrificed herself for the good of the country—she killed her husband and then killed herself. She may also have done this as she hated the boy.
1709 (Hōei 6, 4th month): Minamoto no Ienobu, Tsunayoshi's nephew, becomes the 6th shogun of the Edo bakufu.

January 16, 1710 (Hōei 6, 17th day of the 12th month): Higashiyama dies.
July 7, 1710 – March 22, 1711 (Hōei 7, 11th day of the 6th month – Shōtoku 1, 4th day of the 2nd month): Ryukyuan mission to Edo, the largest delegation—168 people—in the Edo Period.
