Ikenobo is considered the origin of Japanese Ikebana. Ikenobo Ikebana has three major styles: Rikka, Shoka, and Freestyle Ikebana. Rikka first appeared in the 16th century (late Muromachi period) and underwent major developments during the 17th century, illustrating and reflecting the landscape views. Shoka appeared in the early Edo period, and later developed into three major areas that represented, heaven, earth, and human beings. Freestyle Ikebana is the latest Ikebana style developed in modern times. The purpose of this research is to understand the influence of Ikenobo Rikka landscape traditional architecture expression in present times through the study of modern Ikenobo Ikebana expressions. This research attempts to analyze the descriptions of the Ikebana works collected in the “Ikebana work Collections of Ikenobo Tanabata Exhibition” published between 2009 and 2018. The Ikenobo Tanabata Exhibition, dates back to the Edo period, and is the oldest Ikebana exhibition in Japan. Results show that descriptions can be classified into four categories: landscape architecture expressions, legacy of the Ikebana techniques, expressions of human spirits, and finally, expressions of human emotions. In addition, this research examines the effects of landscape architectural expressions of Rikka in modern Shoka and Freestyle Ikebana using KHCoder - a text data mining software.
