Yukinobu Fujino graduated from the Division of Biological Science at the University of Hiroshima's Graduate School of Science. He then joined a long-established flower shop in Hiroshima City, working on bridal arrangements, bouquets, floral arrangements for media shoots and floral displays for retail outlets before opening Fleurs Tremolo in Hiroshima City in 2006. The concept of his flower shop is "to express with flowers the shades and textures of the four seasons that touch all five senses."

Yuji Miura began his career in floristry at the age of 18, working for 16 years at Flowers Nest in Tokyo's Naka Meguro. In September 2014, he opened his own store, Irotoiro. Apart from working in the store, his work includes television commercials, floral installations, decorations and weddings. Reflecting his love of seasonal wildflowers, the store's large branches and arrangements are accompanied by a wealth of delicate flowers to create a casual, relaxed space.

Takanori Shimizu trained at his family's bonsai business for five years, in addition to working for 10 years in flower shops in Kichijoji and Aoyama. In May 2011, he opened Dot Moss in Tokyo's Nishi Azabu, concentrating on both ikebana and bonsai. Aiming to foster people's interest in plants, he continues to come up with new ways of easily incorporating plants as interior objects.

Takaya Yamamura is representative director of Hana Noshou and representative of Deuxieme, the flower shop he opened in Nishi-ku, Hiroshima City in 1999.

Deuxieme opened its Furueshinmachi branch in fall 2015. Yamamura was a finalist in the inaugural Florist Review. He won the Hanaike Battle Spin-Off edition at Daishoin temple in Miyajima in 2014 and in 2015 launched an event called "Connected by Coffee: A Journey with Flowers and Sound" (http://deuxi.jugem.jp/?eid=4089).
