noun
winning a hand (mahjong)
Mahjong term for completing a winning hand. Compare 上がり (sense 5) for general 'finish' or 'rise', and 和了 (ホーラ) for the Chinese-derived reading.
彼はリーチ一発で和了りを決めた。
He won the hand with a one-shot riichi.
和了り牌を引いて、見事に役満を達成した。
He drew the winning tile and brilliantly achieved a yakuman.
The reading あがり is the nominalized form of 上がる (to rise, to finish). The kanji 和了 are ateji borrowed from Chinese mahjong terminology, where they mean 'harmony' and 'completion'.
