Why is Moncler so popular in Japan?

I've noticed that Moncler, a French luxury outerwear brand, seems to have a particularly strong following in Japan. Can you help me understand why Moncler has become so popular there? Is it because of the quality of their products, their marketing strategies, or something else entirely? I'm curious to learn more about the reasons behind Moncler's popularity in Japan and how they've managed to capture the hearts and minds of so many consumers in that market.
