Leaves are thick and soft and usually have violet patterns on its surface. One pale red flower bloom downward at the top of flower stalk (Kakei: stem of flower bearing only flowers without leaves). The flower has 6 petals, which are about 4 to 5 cm long and rolling upward widely. Their name ‘Erythronium japonicum’ (Katakuri) comes from how this plant was written as Katakagono-Hana in "Man-yo-shu", which is one of the most renowned collection of poems at 8th century.
