“A hidden beach where transparent sun pillars shine—where tranquility and beauty exist in perfect harmony.”
Nanakou Bay is a quiet, secluded beach located in the Karimata area of Miyako Island. Just past the Miyako Underwater Park, it sits along a rural farm road, hidden from the view of most tourists. While parking is very limited and spaces are few, the peace and beauty found here are truly exceptional.
The bay’s most striking feature is the appearance of transparent, pillar-like rays of light—known as “sun pillars”—seen above the rocks floating offshore. This rare natural phenomenon occurs when sunlight reflects off the ocean surface or water droplets during sunrise or sunset, creating a mystical and captivating glow. Experiencing this serene scene, surrounded by nature’s quiet, offers a deeply healing moment away from everyday life.
If you seek a peaceful and magical place within Miyako Island’s rich natural landscape, don’t miss the chance to witness the gentle glow of the sun pillars at Nanakou Bay.
