Waves crashing into the Jyogasaki Coast, Izu Penninsula, Shizuoka Prefecture, Japan. "Jyogasaki", written 城ヶ崎, means "next to the castle". The steep cliffs are composed of columnar basalt that forms when lava cools at a relatively slow pace, allowing regular contraction fractures to form. These cliffs resemble the stone walls of Japanese castles.
