Any stores in taipei that sell japanese denim? (Samurai, Studio'Artisan, etc)

Hey guys,

I'm going to Taipei, Taiwan during my christmas break and i've been trying to find out if Taipei has any stores that sell raw denim or selvage. I saw the Taipei Shopping Guide but it doesnt say specifically if those certain stores sell raw denim or selvage. I am mainly looking for Samurai, Studio D'Artisan, and other Japanese denim brands. If you have any info, please help me!!!

Thanks!

yeah i knew that summit and faith sold sugar cane. however, i was wondering if any other stores sold japanese denim such as samurai, studio r, etc. (im not that into sugar cane)
