What is Japanese Summer Vegetable Salad?

Japanese Summer Vegetable Salad is a dish that incorporates vegetables commonly harvested in Japan during summer. It is made with cucumbers, tomatoes, myoga (Japanese ginger), and shiso leaves (perilla), all tossed with shio kombu (salted kelp).

This dish is very easy to prepare, as all you need to do is cut the vegetables and toss them with shio kombu and sesame oil. The crisp texture of the cucumbers, the vibrant color of the tomatoes, the refreshing flavors of myoga and shiso, and the rich umami of shio kombu come together in a harmonious blend of flavors.

Since it uses unique Japanese ingredients, some of which may be hard to find, it is worth seeking them out to make this salad. Once you try it, you will likely want to make it again and again, just like I do.

Health benefits of summer vegetables

The vegetables used in this salad are rich in nutrients that help you stay refreshed during the hot summer. Their specific benefits are as follows:

  • Cucumbers: Provide hydration, help cool the body, aid digestion, are rich in vitamins, and may help prevent high blood pressure.
  • Tomatoes: Provide hydration, help cool the body, boost the immune system, and contain antioxidants.
  • Myoga: Aids digestion, stimulates appetite, and may help prevent high blood pressure.
  • Shiso leaves: Stimulate appetite and have antibacterial properties.

Myoga and shiso are traditional Japanese aromatic vegetables that are considered ideal ingredients for combating hot summer fatigue in Japan. Their distinctive aroma and rich flavor add a delightful touch to the salad.

Enhance the flavor with shio kombu

For flavor, this salad uses shio kombu instead of dressing. Shio kombu is a condiment made by simmering thinly sliced or cubed kombu in traditional Japanese seasonings, then drying it. Can you find it in stores?

If not, you can substitute it with wafu dressing (Japanese salad dressing), but I still recommend using shio kombu, as its rich and unique flavor is truly delightful. You can even make it yourself with kombu that has been soaked in water or already used to make dashi stock. I highly recommend giving it a try-it is definitely worth the effort.
