Feel the sunshine on your skin at Arai Beach. Once you've worked on your tan, stick around and watch the sky turn kaleidoscopic as the sun slowly disappears.
This Kosai stretch of coastline is a good place to start your day of sightseeing. There's plenty to see in the vicinity, such as Hamanako Palpal Theme Park, Lake Hamana, and Hamanako Garden Park. Take your time at Arai Beach before heading to these other fine attractions.
