I do rather wish they'd make a pot one day with a handle on the other side for left-handed folks. I always pour my Japanese tea out away from me into the cup, heh.
Some of Toru's Tokoname listings have left handed versions that are also in stock but you won't see them unless you open the web page for that specific product. He also usually has some left handed kyusu in the Bizen section. And as someone already mentioned, there is a good selection of lefty kyusu on the Tokoname site.
Artistic Nippon Hokujo kyusu with left handed versions available:
