here's my local wool shop in kyoto from the exterior. they sell a lovely variety of corriedale and merino rovings, as well as spinning, felting, and dying supplies and books, both in english and japanese.
i've attended several 'natural' class of a 6 class series that they offer, which were great, and i've posted about them in the 'natural dye journal'. these classes covered carding, spinning, and natural dying. these classes are entirely in japanese, and i would recommend it for anyone who can speak japanese or is living in japan for a long term.
