Many cuisines are defined as much by their ingredients as they are by their techniques. Japan, being a small island with distinct seasons, a culinary tradition with an emphasis on seasonailty, and many years of seclusion from the outside world is a prime example of this. Whether it's meat, shellfish, herbs and spices, or grain-based products, there are certain ingredients that are inherently linked to the cuisine and culture in my mind.
