Cooking with Japanese seasonal vegetables ensures that everything you use is at its freshest, and of the highest quality, making your dishes even more delicious.

In Japanese cuisine, the concept of “shun” (旬) is very important. Shun is the celebration of those ingredients which are at their seasonal peak. Even better, including a variety of seasonal foods in your diet is great for your health, as different foods provide different essential nutrients. 

This concept is still very much present in Japan today. With each seasonal change, the vegetables available in Japanese supermarkets change too.  Here is a list of 15 of Japan’s most popular seasonal vegetables. Perhaps you can include them in your own seasonal cooking as well!
