源頼朝が葦毛の馬に乗ってこの地を通った時、その馬が何かに驚いて沢に落ちて死んだので、この地に埋葬した場所です。キャッシュはその近くの定番のところに設置しました。
When Minamoto no Yoritomo rode through this area on a reed-haired horse, the horse was surprised by something and fell into a stream and died, so it was buried here. The cache was installed in a standard place near it.
