The moon show "Tsukimi" is a Japanese festival to the honor of the harvest moon. Emoji shows the traditional ceremony with Japanese pampas grass, Dango (Japanese dumpling), and the moon in the background.
The moon viewing ceremony emoji was introduced in 2010 and released as part of the Unicode 11.0 standard. This emoji can be found under the activities
category. Because the moon viewing ceremony emoji has been around for quite some time, it should display correctly in the majority of operating systems.
