I can get a chunk of wasabi for about $6 at my local greengrocer in Tokyo. Unless you plan on eating a lot of sashimi at home within the next few days, though, it’s not practical since it goes bad much faster than the tube stuff. The taste is substantially better than the fake stuff, but it doesn’t really matter if you’re eating at a cheap place that doesn’t properly prepare the nigiri rice.
