2026 Shirahama Beach (Minamishimabara City) — Full-Day Course

Centered on Shirahama Beach (白浜海水浴場) in Minamishimabara City, open from Saturday, July 18 through Sunday, August 30, 2026, this full-day course lets you fully enjoy the history and nature of Kuchinotsu at the southern tip of the Shimabara Peninsula. In the morning, stroll the waterfront of Kuchinotsu Port (口之津港), once a thriving international trading port, and encounter the history of the Shimabara–Amakusa Rebellion at Hara Castle Ruins (原城跡), a UNESCO World Heritage component site. Deepen your understanding of the history at the neighboring Amakusa Shiro Memorial Hall (天草四郎メモリアルホール), then rest and fill up on food at Harajo Onsen Masago (原城温泉 真砂), which looks out over the Ariake Sea. The climax is Shirahama Beach in the afternoon. Swimming hours run from 9 a.m. to 5 p.m., and marine sports and jet skis are entirely prohibited, so even families with small children can safely enjoy the water's edge. About 100 free parking spaces are also available, making it convenient to visit by car. Once you've had your fill of the sea by evening, bring your summer day at the Kuchinotsu seaside to a close.
