Large rock with its 3 sides surrounded by bedrock. As it appears to be floating on water, it is also called “Floating Rock”, and it is worshiped as a holy rock at Oushiko Shrine.
According to “Harima no Kuni Fudoki”, it was established in the era of Shotoku Taishi by Mononobe no Moriya.
However, that hypothesis contradicts other indications of the time it was made, and its true origin is still unknown.
When you go through the Torii and go up the approach that is steep stairs, the inner shrine with an unusual structure, which has a corridor at its center, appears. The massive stone structure sitting at the end of this corridor is Ishino Houden, one of Three Great Miracles of Japan. It is 5.6m high, 6.5m wide and 7.5m deep. It is estimated to be 500 tons. Due to the water held in the pit that is cut deep around it, it appears as though it is floating on water, giving it the name of “Floating Rock”.
Though each person feels power from slightly different spots, it’s generally agreed that the back side of Ishino Houden, left side of where there is a triangular protrusion, is that spot that is closest to the holy relic and therefore emits the most power. The way one feels this power is also different from each person. Some feels as if “electric shock is going through”, and others feel like their bodies are “getting warm from touching the stone”.
A holy stone of about 3m tall, which is said to be a sister stone of Ishino Houden. It is believed that when you push this holy stone with all your strength, then caress the weak spots of your body with the hand that pushed the stone, it will strengthen these spots and will give you good luck.
At the Autumn Festival of Oushiko Shrine every October, there is a lively event called “Mikoshi Awase”. 2 mikoshis (palanquin for carrying the holy relic) crashes with each other as though they are wrestling. According to the legend, its originates from the story that during her Expedition to Korean Peninsula (Legendary Military Invasion of Korea in the 3rd Century), Empress Jingu crashed her ships with each other in order to get rid of oysters on them. It is said that more intense the crash gets, more pleased the god becomes.
