considered one of the most significant annual rituals by the Emperor, requiring rites to be conducted from 6 PM to 8 PM and from 11 PM to 1 AM in the presence of only two servants. Due to the physical requirements of the rites, Emperor Hirohito ceased participation at age 70 and Emperor Akihito shortened his participation in stages from age 75 to age 80. The festival is also celebrated publicly at some Shinto shrines such as Sumiyoshi Taisha in Osaka. The Nagano Ebisuko Fireworks Festival (長野えびす講煙火大会) is held on Labor Thanksgiving Day and had 400,000 attendees in 2017.
