There are a lot of flowering words in Japanese one would think are unnecessary, but the sakurako blossom makes them relevant. I believe this means "The first day from which flowers (usually, sakura) are blooming. "輪以上の花が開いた状態となった最初の日をいいます"
満開日 = the day in which flowers (usually sakura) are considered in full bloom (80%+ of flowers in bud).
"満開日とは、標本木で、80%以上のつぼみが開いた状態となった最初の日
をいいます"
They also have a word for the "Sakura line" which is the line up to where the sakura are flowering, but i've forgotten what word it was.
(The Japanese quotes were from a Japanese website, I can't fully understand but they seem to agree)
