Ohara Unshin (小原雲心) (1861–1916) started his own Ikebana school in 1895 when Japan opened up its economy to the West and began to import European flowers.
[1] For the purpose of this art form, he developed shallow, circular, ceramic vases, which became known as the moribana style.
[2] Ohara's son Koun (小原光雲) (1880–1938) invented a descriptive teaching method and moved from individual lessons to group classes.
The inspirations for rimpa came to him from rolling picture scrolls, screens (byōbu) and painted subjects of the 17th century.
On the occasion of the 90th anniversary of the Ohara school in 1985, Natsuki created a new style called hana-mai (dancing flowers) and later the Hana-isho forms.
