Kasugayama Shrine is situated halfway up Mt. Kasuga, where the revered General Uesugi Kenshin from the Warring States period (c. 1465 to 1573) used to reside. This wooden shrine was built by the father of children's literature in Japan, author Ogawa Mimei.
You can reach the shrine by train and then by bus or car.
After taking the Joetsu Shinkansen to Joetsumyoko Station, take the Main Line to Naoetsu Station. Then, transfer to a Kubiki Bus and get off at the Kasugayama-shita stop. The shrine is a 30-minute walk from there.
The shrine is a 15-minute drive from the Joetsu-Takada Interchange on the Joshinetsu Expressway. Free parking is available at the bottom of the shrine.
On the shrine grounds, you'll find animal statues that are fairytale motifs and relics and documents that belonged to Uesugi Kenshin.
If you'd like to get in a little exercise, take a hike up to the top of Mt. Kasuga to look over the city of Joetsu. It is not a difficult hike, and the trail passes through important castle ruins dating back to wartime in the Warring States period.
Nearby Rinsenji Temple is worth checking out since that is where Kenshin studied and trained in military arts.
Every year on the fourth Saturday and Sunday in August, hundreds of samurai actors (volunteers from the city) dress in full armor and march the streets of Kasugayama for the Kenshinko Festival, which commemorates Kenshin.
The highlight of the festival is undoubtedly the reenactment of the Kawanakajima Battle; hundreds of actors and horses are involved in this performance.
