Yudo Ishibashi, the founder of the Kado Sensho Ikenobo school of Ikebana, was born in 1880 in the Saga prefecture of Japan. He was the second son of Tokuemon Ishibashi, a Samurai. At the age of five, he adopted his mother's family name and was known thereafter as Yado Moroizumi. His early interests included, Kado, flower arranging, and Chado, tea ceremony. He was an adept student of both. Yudo studied flower arranging at the Ikenobo school and became very well-known around Kyushu.

In 1918, he was appointed to the head of the Ikenobo School, Fukuoka area. In 1921, he was in charge of all prefecture in Kyushu and became active in the school politics as well as in flower arranging. In 1928, he started teaching at Ikenobo School headquarters, Honbu and was appointed to the positions of Kamkacho, heading the arrangement section. In this role, he spread knowledge of the Ikenobo School. At this time, the Ikenobo School only taught the classsical forms of arrangement and did not teach modern forms.

Moroizumi sought permission from Ikenobo's Iemoto, to approve the teaching modern forms and also to allow a more democratic process within the school by including a board of directors. This was veto by the Iemoto. Moroizumi then sought permission to start his own school which was granted and the Sensho Ikenobo was offically opened in 1930. Sensho Ikenobo pass away in 1950 and his son became the new Iemoto. Yoriko Moroizumi is the current Iemoto, the great granddaughter of Yudo Moroizumi.
