Ikuzō

Ikuzō is not a traditional given name in Japan but rather an exclamation or phrase. It is a colloquial and energetic way of saying "Let's go!" or "Here we go!" in Japanese. Its use as a personal name is highly unusual and would likely be a modern, perhaps whimsical, choice, or a nickname derived from the phrase itself rather than a name with historical etymological roots as a proper noun.

The phrase 'Ikuzō' (行くぞ) is composed of the verb 'iku' (行く), meaning 'to go,' and the volitional/exclamatory particle 'zo' (ぞ), which adds emphasis, determination, or a call to action. While Japanese names often have meanings derived from kanji characters, 'Ikuzō' in this form is a phonetic transcription of a spoken phrase, making its origin distinct from most traditional Japanese names.
