2026 Mikawa Oshima East Hamahama Beach 1-Day Full Experience Course

A full-day course that makes Mikawa Oshima East Hamahama Beach (三河大島東浜海水浴場)—which opens from July 18 (Sat) to August 19 (Wed) 2026—the star of the show, and allows you to enjoy all the highlights of Gamagori City from morning onwards. In the morning, the whole family can get close to marine life at Takeshima Aquarium (竹島水族館), which features everything from colorful tropical fish to deep-sea creatures, then cross the red bridge to visit Yaohototomi Shrine (八百富神社) on Takeshima Island. For lunch, enjoy local seafood at Gamagori Seafood Market (蒲郡海鮮市場). The climax comes in the afternoon at Mikawa Oshima East Hamahama Beach. On the calm sandy beach facing Mikawa Bay, you can enjoy water play to your heart's content until evening. The venue is at Mikawa Oshima East Hamahama in Gamagori City. Bring your swimsuit and towel and head out to summer in Gamagori. Whether you prefer relaxing while gazing at the sea, building sand castles at the water's edge, or anything in between, each family member can enjoy a perfect summer day at their own pace.
