It is customary that dancers selected for the Hono-mai (a Shinto dance for dedication) in the Kamo no rinjisai (Kamo Special Festival) and Iwashimizu-rinji-matsuri (Iwashimizu Special Festival) always use sekitai with agate, and although only shosho usually use an agate sash (an imperial envoy for special festivals was selected from among chujo and shosho), they are permitted to put on a rhinoceros horn sash on this occasion.
ちなみに、賀茂臨時祭・石清水臨時祭の奉納舞に選ばれた舞手は必ず瑪瑙の石帯を使うのが慣例であって、本来瑪瑙の帯を使うのは少将だが（臨時祭勅使は中・少将から選ばれる）この時だけは犀角の帯をつける。
