Komatsuna — The Leafy Green Japanese Superfood

[EDO BEAUTY LAB] is the first skincare line that uses komatsuna — the leafy green Japanese superfood. Find out more about brand, our star ingredient, and how we’re committed to supporting our local community. 

The History of Komatsuna

Komatsuna (Brassica rapa var. perviridis) first arrived in Japan via China somewhere between the 8th and 12th centuries. Later, around the 13th century, it made its way to Edogawa City, in eastern Tokyo. Here, it became a staple crop in the Komatsgawa area. In those days, komatsuna was known as “fuyuna,” or “winter vegetable.”

A local legend attributes the renaming to Tokugawa Yoshimune, the eighth shogun of Japan:

As the story goes, one day Tokugawa had a bowl of fuyuna soup after an episode of hunting in the Komatsugawa area. Surprisingly, he liked the leafy green vegetable so much that he christened it “komatsuna.” ( Komatsu vegetable.)

Today, Edogawa City prides itself on its komatsuna production. In fact, it is Tokyo’s leading komatsuna producer, with 2,848 tons harvested in 2018. Moreover, komatsuna is such an important part of Edogawa City that it hosts a yearly “Komatsuna Festival.” What’s more, Edogawa City even has a komatsuna mascot!

Nutrition and Culinary Uses of Komatsuna

Komatsuna is high in nutritional value. As a matter of fact, komatsuna is a true superfood and contains 3.5 times more calcium than spinach. In addition, komatsuna is also rich in antioxidants which nourish the skin and create a healthy glow.

100 grams of komatsuna contains:

Calcium: 170 mg 

Iron: 2.8 mg

Vitamin C: 39 mg

Dietary Fiber: 1.9 mg 

(江戸川の小松菜はエライ!, n.d.).

Not only is komatsuna rich in nutrients, it also compliments both Japanese cuisine and Western dishes. In Japan, komatsuna is an ideal ingredient to add to soups, sautées, and salads.

However, take a trip to Edogawa City, and you’ll find komatsuna noodles and pizza with komastuna toppings. Surprisingly, komatsuna works well in Japanese sweets, bread, chiffon cakes, and other confectioneries.

What’s more, Tokyo Sea Life Park, an aquarium in the Kasai district of Edogawa City, even uses komatsuna to feed some species of aquatic creatures!
