How Japanese names are chosen

Japanese parents choose the sound and the characters as two separate decisions, and the second one is where the tradition bites. Seimei handan — literally name divination — counts the brush strokes in the written name and reads fortune from how those counts combine across five values known as the Five Kaku. Surveys put the share of parents who weigh stroke counts at around 70%, and professional naming consultants, meimei-shi, make a living advising on it. The practical consequence is a swap rather than a rethink: a name whose stroke count comes out unlucky is rewritten with different kanji of the same reading until the numbers behave.

One reading can be written many ways — Yuuki alone has dozens of kanji spellings — so the written form carries information the pronunciation does not.
