You can cook Japanese food with the ordinary equipment of a typical Western kitchen. Japanese implements, however, do some jobs more efficiently and better than Western substitutes. If you have the means and opportunity to obtain some of these utensils, I recommend that you do so. With your new tools, you may find that preparation times are shorter, cooking tasks are easier, and the dishes you produce look much better. You will find these tools very valuable for preparing non-Japanese foods, too.
