Apparently the sand is imported from Australia, and I'm inclined to believe it as tr sand in the surrounding beach is more like gravel.
We went there in mid-August by car, and that costs around ¥15000, and parking ranged from ¥1000-¥2000 per day.
It is crowded, and most of the people are sleeping in the sun. The sand is beautiful, as well as the water. But the water is warm. Draw your own conclusions.
It's a nice beach if you miss real beaches, but be prepared to pay a premium for the experience.
