真山神社に伝わる「柴灯祭(せどまつり)」に登場するなまはげは、神の使者である「神鬼(しんき)」の化身とされています。境内には樹齢1100年を超えると言われる神木の榧(かや)の木があり、こちらも必見です。
本殿への「お山かけ」
おっしゃる通り、現在の拝殿からさらに真山(標高567m)の山頂を目指して登山道を上った先に本殿があります。古くから修験者が歩いた霊場としてのエネルギーを肌で感じられる、本格的なパワースポットです。The Namahage, who appear in the Sedo Festival at Mayama Shrine, are considered to be incarnations of "Shinki," messengers of the gods. Within the shrine grounds stands a sacred kaya tree said to be over 1100 years old, which is also a must-see.
The "Mountain Climb" to the Main Shrine
As you mentioned, the main shrine is located at the top of a mountain trail leading from the current worship hall towards the summit of Mount Mayama (567m above sea level). It's a genuine power spot where you can feel the energy of a sacred place where ascetic monks have walked since ancient times.
