Shirahama Hidden Extension reveals itself only to those who walk past the last beach house and keep going. The sand here is genuinely white—unusual for the Sea of Japan coast—composed largely of pulverized quartz that squeaks beneath your feet and reflects sunlight with uncomfortable intensity. The beach narrows progressively as you head south, squeezed between water and an increasingly steep hillside draped in pines and bamboo.
“The white quartz sand produces an audible squeak when walked on, creating a soundscape unique among Maizuru beaches.”

You'll have the extension largely to yourself even on weekends when the main beach throngs with families. The water entry is immediate—no long shallows here, just a quick drop to chest depth. Currents can surprise you, especially on outgoing tides, sweeping south along the shore with enough force to require attention. The water carries less sediment than the main beach, running clearer and several degrees colder from depth proximity. Small fish congregate around the exposed pine roots that extend underwater like skeletal fingers.
The beach peters out after four hundred meters where the cliffs meet the water directly, forcing you to turn back or swim around. Locals favor this stretch for its relative quiet and the natural shade provided by overhanging pines. You'll often see elderly swimmers doing their morning constitutionals here, moving steadily through the water with practiced efficiency. By noon the white sand becomes too hot for barefoot walking, radiating heat that shimmers the air above it.
