Shrine near the top

There was a small shrine under the big rock near the top of Mt. Nagata-dake.
 I knew there was a traditional event for local residents in the island which bring the sea sand from the beach and gave it the god. It was a rare event.
I could sea sand and bamboo which be used as a case for sand. I prayed for the traditional event for a while and I started to return to main climbing road.
