Japanese name meaning "century," "vitality," or "star radiance," depending on kanji used.
Seiki is a Japanese name whose meaning can vary with kanji, including senses such as century, vitality, or star radiance. That flexibility is characteristic of Japanese naming, where the written characters determine the semantic load.
The name therefore feels compact but potentially rich in implication. Seiki sounds clean, modern, and efficient, with a polished simplicity that travels well. Depending on the characters chosen, it can feel historical, energetic, or luminous.
That makes it a name of subtle depth rather than obvious symbolism. Seiki has the spare elegance often associated with Japanese names, where meaning and sound work together with quiet precision.
