It turns out that the name Yuki can be spelled in Japanese (specifically, in kanji) in 14 different ways: 雪, 幸, 由紀, 由貴, 由岐, 由樹, 友紀, 夕希, 有希, 勇気, 有機, 祐樹, 雄輝, and 雄樹. All these are valid names pronounced as Yuki. You can also add the spellings in hiragana, ゆき (ゆうき) and katakana, ユキ (ユーキ). That’s why they use business cards 😉
