Namiita Beach and Kiri Kiri Beach. Namiita = surfing they have a rental shop. Kiri Kiri = relaxation. In Namiita, there is the cutest little tea/cake shop a little walk from the beach. It is right in front of the train stop. You can eat beautiful little cakes and drink matcha that you make in little tatami mat rooms. Feels like you went back in time.
Also, Shiroyama Parkãåå±±å ¬å. Climb up the little mountain and see beautiful views of the town, mountains, and sea.
