Please help me. I am starting to teach a basic zill and movement class in January. I own many zills but I have always ordered from American sites (http://dwp.bigplanet.com/saroyan/) or bought from other American dancers. I don't know how many of my students will have good quality zills...or how many of my students will even speak English. Before I teach I want to make a list of Japanese websites and Tokyo-based stores where students can buy good quality zills. . Where do you suggest?
