"Variant of Joshua"
The name Yoshua is commonly a male name from the "Hebrew" origin.
Yoshua is a form of Joshua, the English rendering of the Hebrew name Yehoshua. The spelling matches how Joshua is written in Japanese, where the biblical name is transliterated Yoshua, and similar spellings appear in other languages' renderings of the same name. It is the same name as Joshua rather than a separate name with its own meaning.
Joshua means "God is my salvation, Jehovah saves.".
The pronunciation of Yoshua is yo-SHOO-uh.
