How do you spell Darius in Japanese?

There isn't one single "correct" way to spell Darius in Japanese, as the romanization of names is not standardized and depends on the desired pronunciation and the writing system used (hiragana, katakana, or kanji).

Here are a few possibilities, using katakana (most common for foreign names):

* ダリウス (Dariusu): This is a straightforward transliteration, using the sounds closest to the English pronunciation. This is probably the most common and easiest to understand.

* ダリアス (Dariasu): A slightly altered version, shortening the "u" sound.

The choice depends on context and personal preference. There's no "right" or "wrong" answer unless a specific Japanese source uses a particular spelling. If you're writing it for a Japanese-speaking audience, the first option (ダリウス) is likely the safest bet.
