In the Muromachi era, the flower arrangement that lost religiosity became a target of solely aesthetic appreciation and simple daily interior decoration called “tatehana.” The article in “Tokikuni kyoki” indicates that the imperial family accepted tatehana under the influence of cultural and environmental changes that later culminated in what is collectively called the Muromachi culture, which brings along the overwhelming dominance of the shogunate in the relationship between the Muromachi bakufu and Imperial Court. Emperor Go-Tsuchimikado grew fond of tatehana decorating the alcoves and shelves according to the shoin-zukuri style in shogun palaces in the Muromachi period, which became the place of refuge from the Onin War. The shoin-zukuri style was introduced to the Imperial Palace that was constructed and renovated under the leadership of the Muromachi shogunate, and tatehana was adopted as a decorative object to be placed upon the alcoves and shelves of the palace.
