The mausoleum of the Uesugi Clan is located in Yonezawa in Yamagata Prefecture. The Uesugi-ke-byousyo is the final resting place for the long line of the Uesugi clan.
The tomb of the clan founder, Kenshin Uesugi, can be found in the center of the mausoleum, while the tombs housing the remains of up to 12 generations of his descendants spread out to both sides. The tombs for the 2nd to 8th generation descendants are made of Japanese zelkova with circular columns and are in the Yashiro architectural style. Tombs for the 9th to 12th generation descendants are made from Japanese cedar and cypress with simple square columns, built in the Hougyou architectural style at the request of the 10th generation Youzan. Either way, the styles of the tombs show the personality of the Uesugi clan perfectly.
The remains of founder Kenshin Uesugi were placed in a jar along with his armor and were transported from Echigo-kasuga-yama (present day Jyouetsu City, Niigata Prefecture), via Aizu (present day Aizu-wakamatsu City, Fukushima Prefecture) and Yonezawa Castle, and finally to the Uesugi-ke-byousyou in the 9th year of the Meiji period.
Yonezawa Clan Uesugi Clan Mausoleum was designated a National Monument in January 1984.
