Water Play in the Calm Inlet of Sanmiku Bay
About this spot
Sanmiku Bay, located in the middle of the Sada Misaki Peninsula, is a calm inlet known as a natural harbor protected by surrounding mountains. The gentle, wave-free waters make it safe and enjoyable for families with small children to play in the water. The bay's distinctive and intricate coastline and clear, transparent sea are major attractions, offering a perfect spot to escape the hustle and bustle of city life and enjoy leisurely time. Viewing the bay in daylight where tonight's fireworks will take place helps you plan the best viewing spot for the evening.

2026年8月2日(日)開催、佐田岬半島の三机湾を舞台にした夏祭りです。山に囲まれた静かな入り江に約2,000発の花火が次々と打ち上がり、穏やかな海面に光が映り込む幻想的な光景が広がります。都会の花火大会とは異なる、半島の入り江ならではの静けさの中で楽しむ花火は、格別の趣があります。海遊びと港町散策で過ごした1日の締めくくりに、家族でゆっくり花火を楽しみましょう。
