cherry blossom glow; radiance of cherry blossoms at dusk
Poetic term for the soft, luminous effect created by cherry blossoms in full bloom, especially at twilight or under moonlight, when the pale petals seem to light up the surroundings.
夜桜の下では、花明かりで本が読めるほどだった。
Under the night cherry blossoms, the glow was so bright you could read a book.
春の宵、花明かりに照らされた小道を歩く。
On a spring evening, I walk along a path lit by the cherry blossom glow.
Compound of 花 (hana, 'flower', specifically cherry blossoms) and 明かり (akari, 'light'). The term evokes the traditional Japanese appreciation of the transient beauty of cherry blossoms and their ethereal glow in dim light.
