History
The name ‘komatsuna’ means ‘greens of Komatsu’ in Japanese, a reference to the village of Komatsugawa in Edogawa, Tokyo. Here it was heavily grown from between 1603 and 1867.
It is said to have been named the eighth shogun, who visited Edogawa in 1719 after eating this tasty local vegetable in soup, naming it after the local river, Komatsu. Since that time the vegetable has been bred to have a sweeter flavor.

Parting Thoughts
Whether using in soup, stir-fry, or even to make soy sauce pickles, this is a vegetable that is loaded with Vitamin A, Vitamin C, and Folate, which is especially important during pregnancy. According to the Mayo Clinic, aim for 400 micrograms (mcg) a day of folate or folic acid before conception. And then 600 to 1,000 micrograms per day throughout pregnancy. To get the most accurate measurement, use a kitchen scale.
