Can anyone from Japan tell me about the store brand Earth Music Ecology? -

This is a store that has opened in Tokyo Japan. Their brand of casual clothes are earth music and earth music ecology. Can anyone give me the main plant fibers used in creating these clothes? The price range, and if they are available online? I found very little info and I had to run that through a translator. Any helpful info would be appreciated.

Made of bamboo very expensive no outlets in US
