Before the beach opens each year, people of the nearby community volunteer to come out to clean the beach, where, at the side of pine trees, bloom a variety of flowers such as rugosa roses (local people call them 'hamanashi'), 'sasa-yuri' (Japanese lilies) and 'oni-yuri' (tiger lilies).
海開きの前には、村人総出のボランティアで海開きの前に「浜掃除」がされ、地元では「ハマナシ」(学名)と呼ぶ「ハマナス」や「ササユリ」「オニユリ」が松林のそばに咲き乱れる。
