Japanese cuisine, known as "washoku," is rooted in centuries of tradition and has evolved significantly over the past 500 years. Japan's geographic isolation, religious practices, agriculture, trade, and interactions with neighboring countries have all influenced its culinary landscape. Here is a broad overview of foods that have been consumed in Japan over the last five centuries:
-
Rice: Central to Japanese meals for centuries, rice is the primary staple. It's eaten plain (gohan) or used in various dishes like sushi, onigiri (rice balls), and mochi (rice cakes).
-
Fish and Seafood: Given Japan's island nature, seafood is a significant part of the diet. Techniques include sashimi (raw), grilled, stewed, or deep-fried (like tempura).
-
Vegetables: Seasonal and regional vegetables have been consumed for centuries. These are often pickled (tsukemono), stewed, or served in salads.
-
Soy Products:
- Tofu: Soft soybean curd used in various dishes.
- Natto: Fermented soybeans, an acquired taste even for some Japanese.
- Miso: Fermented soybean paste used in soups and various dishes.
- Soy Sauce: Made from fermented soybeans and used as a seasoning and marinade.
-
Noodles:
- Udon: Thick wheat noodles.
- Soba: Thin buckwheat noodles.
- Ramen: Chinese-inspired wheat noodles in broth which became particularly popular in the 20th century.
-
Tea: Consumed for centuries, green tea varieties like sencha, bancha, matcha, and gyokuro are common. Matcha, a powdered green tea, is used in the traditional tea ceremony (sado).
-
Sweets:
- Wagashi: Traditional Japanese sweets often made from mochi, anko (red bean paste), and fruits. These are often consumed with tea.
- Kasutera (Castella): Sponge cake brought by the Portuguese in the 16th century.
-
Preservation Techniques:
- Pickling: Foods like vegetables and fish were preserved using salt, vinegar, or fermented rice bran.
- Drying: Seafood and vegetables were often dried for preservation.
-
Meat: For much of Japan's history, especially during Buddhist-influenced periods, the consumption of four-legged animals was limited or taboo. However, this began to change in the late 19th century during the Meiji Restoration when the country opened up to Western influence. Dishes like tonkatsu (breaded pork cutlet) and yakiniku (grilled meat) emerged.
-
Seasonings and Condiments:
- Wasabi: Spicy root used as a condiment, especially with sushi.
- Mirin: Sweet rice wine used for cooking.
- Dashi: A broth made primarily from kombu (kelp) and bonito flakes, forming the base for many soups and sauces.
- Alcohol:
- Sake: Rice wine with a history spanning over a thousand years.
- Shochu: A distilled spirit made from various ingredients, including barley, sweet potatoes, and rice.
- Foreign Influences:
- By the 16th century, the Portuguese introduced tempura.
- The late 19th and 20th centuries saw a surge of Western influences, introducing dishes like curry rice, spaghetti, and bread.
Over the centuries, seasonality and regional variation have played significant roles in Japanese cuisine. While the core elements of rice, fish, and vegetables remained, the way they were prepared and presented evolved, blending tradition with innovation. The commitment to fresh, high-quality ingredients and aesthetic presentation has remained a hallmark of Japanese cuisine.
