I've been searching for KI most of the day without success. Those who still have it are price gouging, in one case raising the price almost 4,000% ($395 for a 14-tablet supply! Really, BP Medical Supplies?). But most everyone I've contacted is quote 4 to 8 week delivery.

And no, it's not for me. The company I work for has over 10,000 employees in Japan, and my group deals with several dozen regularly. When we heard they were not available in Japan we were going to put together a fedex, but so far no luck in finding them in-stock.
