The first time I saw them I wondered, “What are those things?”
They made me feel a little bit nervous. They were nice to look at but I didn’t feel like walking on them the same way that I’d like to walk on a beach.

Ohama, Okinawa (大浜)
Kaiyuan Fishing Harbor (開元漁港) Lanyu, Taiwan
Haeundae Beach, Busan, South Korea
