Shirahama Beach (白浜海水浴場)

Flow of the course

About this spot

Shirahama Beach in Kuchinotsu-cho, Minamishimabara City, is open in 2026 from Saturday, July 18 through Sunday, August 30, with swimming hours from 9 a.m. to 5 p.m. From the sandy beach facing the Ariake Sea, you can look out toward the Amakusa Islands, and because it's a quiet inlet the waves are gentle, creating an environment families with small children can enjoy with peace of mind. The beach has a rule banning all marine sports and jet skis, which also helps keep the swimming area safe. About 100 free parking spaces are available, making access by car convenient too. Enjoy the summer sea to the fullest until evening, from playing at the water's edge to building sandcastles.

Season & hours

Tips

Since swimming hours end at 5 p.m., it's a good idea to wrap up about 15 minutes early to leave time for changing. The summer sun on the sand is strong, so be sure to bring sun protection and stay hydrated. Since marine sports and jet skis are banned, play centers around swim rings and other simple water toys.

Best time to visit

After 2 p.m., the sunlight softens a bit, making the afternoon a great time to enjoy the sea fully until evening
