noun
evanescent glory; passing prosperity
A yojijukugo meaning that glory or prosperity is as fleeting as the morning glory flower, which blooms for only one day. Used in literary or reflective contexts.
栄華を極めた彼も、槿花一日の如くその地位を失った。
Even he, who had reached the pinnacle of glory, lost his position as fleetingly as the morning glory blooms for a day.
From the Chinese idiom 槿花一日 (jǐnhuā yīrì), literally 'hibiscus flower one day', referring to the short-lived bloom of the hibiscus (or morning glory). The exact historical derivation is uncertain, but it is used in Japanese as a yojijukugo to express the transience of worldly success.
