[Update 3: 8/5/2011] For a NEW reliable retail seller of Kiseru pipes and Koiki Tobacco please read this.
[Update 2: 10/15/2010] After some investigation and consultation with local pipe shops, the KISERU is apparently considered a "one hitter" pipe and as such is categorized as nothing more than another possible pot pipe. None of the major pipe/tobacco retailers I spoke with wanted anything to do with such "one hitters" citing major federal and state regulations. Even the head shops on Clark/Belmont Avenue, which indeed sell one-hitter pot pipes, wanted to pursue the sale of Japanese tobacco (again, citing federal/state regulations). I will continue to pursue this, though it seems the only likely current scenario is that the Kiseru pipes will be sold by a head shop and NO Japanese tobacco will be available.
[Update 1] I have been informed that as of 9/1/2010, LSANDO no longer supports the sale of Kiseru for overseas shipping. They have removed the English-translated pages from their site. The links on this page now point to only Japanese-language pages. SaruDama intends to verify with LSANDO what their policy now is regarding oversea shipping/processing and if necessary seek out an alternative location from which readers in the U.S. might obtain Japanese kiseru and tobacco.
LSando.com has a new collection of Kiseru Pipes
Living Shop Ando [LSando.com] is to my knowledge the only authentic (geographically and culturally) Japanese pipe shop which offers international currency and shipping for its excellent selection of traditional Kiseru pipes, carrying cases and the exclusively Japanese Koiki tobacco used for Kiseru. I have personally purchased from them and consider them top-notch. (You can find pics and descriptions of my purchases HERE.)
ANYWAY... LSando has just come out with its new collection of Kiseru pipes and cases if any of you are interested.
LSando is located in Tokyo Japan and thus declares it prices in YEN. However, there is a currency conversion calculator at the bottom of the page which will tel you up front what price you can expect to pay in Yen.
If in fact you choose to purchase from Ando-san, please mention that you learned of his shop via SaruDama. I think he may appreciate that.
