In contrast to the works of Zeami and Motomasa KANZE, in which 'yugen' (elegance, calm, profundity, mixed with the feeling of mutability) was sometimes too much expressed, many Nobumitsu's works were spectacular filled with sensational events which were called 'furyu' (full of refined tastes) in those days.
「幽玄」を時に過剰なまでに追求した世阿弥・観世元雅の作品とは対照的に、信光の作品は、ショー的要素、同時代でいう｢風流（ふりゅう）｣を多く取り入れた華やかな作品が多い。
