羊毛とおはな was a Japanese acoustic duo formed by guitarist Kazunori Ichikawa (born 26 July 1981) and vocalist Hana Chiba (born 31 January 1979). The pair met in 2003 and began performing in local venues, gaining attention for their blend of pop and rock. They released the live recordings Live In Living ’07 (November 2007), Live In Living ’08 (July 2008), and Live In Living ’09 (July 2009). In July 2011, they released the single "世界は踊るよ、君と。" and later that month the album 月見草. The duo signed with LD&K Records, and their song "Fuyu no Uta" was featured in a Taiwanese TV commercial after the Great East Japan earthquake, leading to a concert in Taipei. The group disbanded following Hana Chiba’s death on 8 April 2015, and her legacy continues through posthumous releases and commemorations of their contributions to Japanese acoustic music.
