I don't think there is a name in English for the weaving supply shop. It was in an older area of Kyoto and the shop owner spoke limited English. I got by with pointing (politely of course), very limited amount of japanese and the ability to read kanji from the price list. We were there for more than an hour, looking at different types of boat shuttles: apparently, there are different shapes for use with cotton, silk, wool, etc.
From top to bottom (in pairs): all purpose boat shuttles (with rollers and these beautiful copper tips. The tips are not weighted as fly shuttles. I think that they are there to protect the ends.), medium size shuttle suitable for pick up, small size shuttle for pick up. Note that there is a small hole on one side and a slot on the other of each shuttle. The small round hole is for fine silk and the slot is for thicker yarn.
I think that I will not have to buy yarn for a while now. (You have yet to see what I got when Edith (from Cloth Haven) took me to the wholesale places in Hong Kong! ) It will take me a long time to use up all this yarn. I am hoping that my yarn will not go the same 'obese' way as my fabric stash. My output needs to catch up with the input, and I am a slow weaver......
