The origins of the names are different from each other as described below, but at present, most people often confuse them, as some shops sell it labeling 'ohagi' in spring or labeling 'botamochi' in fall, although in spring it should be called 'botamochi' and in fall it should be called 'ohagi'.
呼び名の由来については後述の通りだが、小売店等では春に「おはぎ」、秋に「ぼたもち」として販売していることも珍しくはなく、ぼたもちとおはぎとの区別は次第に薄れている。
