There's also a wide range in terms of price - from teapots for 500 Yen to a single cup/saucer set for 15,000 Yen (um, not really in my budget). I think we were all a little cautious with our purchases because we didn't know what the next store might have and perhaps the next store might have something we'd like better. A few good things to note about many of these stores: (1) many of them take U.S. credit cards; and (2) many of them will ship your purchases worldwide.
At the end of the day, none of us really went too crazy. I had my eye on this teapot that matched the pink teacups and plates that I got from the 100 Yen store a few weeks ago, but for whatever reason I didn't get it. Well actually I do KNOW the reason - the reason is that I thought I might see something better at another shop and I didn't want to be stuck with it if that were that case, but it turned out that I didn't find a better one, so I ended up with none. In fact all that I left Kappabashi-Dori with was a bundt pan (which I've been wanting), a plain white teapot for a single cup of tea, and a mortar/pestle (which I've been needing). However, a day or 2 later, I got a text message from one of my friends expressing regret over not having bought everything she was considering buying....oh well, guess it looks like another trip to Kappabashi-Dori is in our future.
