Japanese Cuisine
Japanese cuisine, like French and Greek cuisines, favors simple dishes of few ingredients. Rather than searching for complex combinations of ingredients, these cuisines focus on the perfection of the ingredients and their preparation.
Japanese cuisine has a rather unique level of skillful preparation technique. Sushi preparation is as much about visual art as it is about flavor and culinary skill.
Many other styles of cuisine do not depend quite so heavily on the combination of these facets, which, to some extent, makes Japanese cuisine one of the more difficult to master.
However, be not afraid, many Japanese dishes are still doable even to a novice (like me), and all dishes are fun to create if you have the patience and resolve to work it out.
