Jōō (Edo period)
Japanese era from October 1652 to May 1655
Jōō (承応), alternatively romanized as Jō-ō or Shōō, was a Japanese era name (年号, nengō; "year name") after Keian and before Meireki. This period spanned the years from September 1652 through April 1655. The reigning emperors were Go-Kōmyō-tennō (後光明天皇) and Go-Sai-tennō (後西天皇).
Change of era
1652 Jōō gannen (承応元年): The era name was changed to Jōō (meaning "receiving answers"), which was to mark the death of the third shōgun, Tokugawa Iemitsu. The previous era ended and a new one commenced in Keian 5, on the 18th day of the 9th month.
The name of this new era came from the Book of the Jin: "The Xia and the Shang dynasties follow their destinies, so the House of Zhou came when it was time." (夏商承運、周氏応期)
Events of the Jōō era
October 3, 1653 (Jōō 2, 12th day of the 8th month): A violent fire destroyed a large part of the Imperial palace and many temples which were nearby. Shortly thereafter, several girls, aged 12–14 years, were imprisoned for having started this fire and others in Heian-kyō.
August 18, 1654 (Jōō 3, 6th day of the 7th month): A famous priest, Ingen, arrived at Nagasaki from China. His intention was to reform the practice of Buddhism in Japan.
October 30, 1654 (Jōō 3, 20th day of the 9th month): Emperor Go-Kōmyō died of smallpox; and his funeral ceremonies were at Sennyū-ji (泉涌寺,, senyō-ji) on the 15th day of the 10th month.

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 25, 2026. The linked authority identifier is Q1145081. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1652, 1655, 1653 and 1654.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
