Shimai is performed only to the accompaniment of Noh-jiuta (Noh chorus), and donning of Montsuki hakama (formal Japanese attire for a man, consisting of a kimono dyed with the family crest and a long, loose, pleated skirt) or kamishimo (samurai costume, old ceremonial costume), instead of wearing Noh costumes and Noh masks.
伴奏は能地謡のみによって行われ、能装束・能面は用いず、紋付袴か裃などで演ずる。
