Is Woo Chinese or Japanese?

I'm curious to know, could you clarify for me whether WOO is of Chinese or Japanese origin? It's a name that seems to have roots in both cultures, and I'm eager to understand the background behind it. I've seen it used in various contexts related to cryptocurrency and finance, but I'm unsure of its etymology. Could you shed some light on this matter, and help me distinguish whether Woo is predominantly associated with China or Japan?
