Where is UNIQLO made?

I'm curious to know, where exactly are UNIQLO's products manufactured? Are they produced in a single location, or do they source from multiple factories across the globe? Are there any ethical or sustainability considerations that go into the selection of these factories? I'm particularly interested in understanding the company's approach to ensuring fair labor practices and minimizing environmental impact in their supply chain. Could you elaborate on UNIQLO's manufacturing process and the steps they take to ensure quality and responsibility in their production?
