The samurai-themed Echigo Joetsu Uesugi Omotenashi Troupe was formed to promote tourism and local culture in Joetsu through live combat reenactments, talks, and tours of historic sites. The ensemble embodies historical figures, including the warlord Uesugi Kenshin (1530–1578) and some of his retainers.

The troupe was formed in 2011 and appears regularly at local events such as the annual Lord Kenshin Festival. Its members maintain an active online presence, including a YouTube channel that features performance clips and videos about local food and culture. Their base of operations is Kenshin Sengoku Emakikan Gallery (the Joetsu City Archaeological Center).

Uesugi Kenshin, the lord of Kasugayama Castle in the sixteenth century, is a common subject of the Gallery’s exhibitions. The Omotenashi Troupe can be booked to provide guidance to exhibition visitors, who can also try on replica samurai armor for a photo opportunity.

The Joetsu City Archaeological Center is dedicated to the research, storage, and display of artifacts excavated from the Kasugayama Castle Site and its surroundings. The Center is located at the foot of the site and organizes exhibitions that highlight the history of the city of Joetsu through material culture.
