Wasabi
Have you tried fresh wasabi? To me, wasabi is a type of art, defines and type of essence of Japan. I am not talking about the green paste or stuff that comes in a tube or packet with your obento, or at the kaiten sushi. If you can, please try to experience real, freshly grated wasabi. This is a rhizome, and if you buy it at Tsukiji or in the super market, it will not be cheap, but worth it. Chefs in a bit more expensive J-restaurants will have a shark skin grater, and grate it fresh, just before you enjoy with the sashimi or the other J-dishes, even steak. It is hot and yet even sweet. Do you know about Daruma vs Mazuma varieties? Try and enjoy real, not imitation wasabi with your washoku, and enjoy!
