Kankanedo

Kankanedo, a cave formation just beneath the ridge, is where sounds softly reverberate like a whisper from the rocks. The caves are assumed to have been constructed over tens of millions of years by wave erosion, and there are four in total, thought to have been formed from three directions (sea-side, land-side and ceiling-side). The name "Kankanedo" is supposed to come from a combination of two Japanese terms. "Kari ga ne" (goose call) is the first, and "kagi kake" is the second (to lock). Both of these phrases are related to the Japanese name for the caverns. To the north, along magnificent Blur Sand Beach, you'll find Kamoaosa Village, and further along, the stunning beauty of Sakurajima Beach, which begins at Tenga Cape and is rightly titled "Beach Garden."

Kankanedo Sea Cave, the tallest of the Oga Peninsula's caves, was created by wave erosion of rhyolite volcanic rock and land jutting from the sea. The light streaming in and the sound of the waves give it a mystical air, with holes opening onto the sea, land, and sky (ceiling). An iron lock was claimed to have been placed on the cave's rock wall in the past, giving it the name Kagikakedo, or Locked Cave, which later became Kankanedo.
