History

Katori Shrine of Shin-Koiwa

The name komatsuna means 'greens of Komatsu' in Japanese, a reference to the village of Komatsugawa [ja] in Edogawa, Tokyo, where it was heavily grown during the Edo period.[1] It was named by Tokugawa Yoshimune, the eighth shogun, who visited Edogawa in 1719 for hunting and stopped at the local Katori Shrine for lunch. The shrine priest served him soup with a rice cake and a local leaf vegetable. The shogun was impressed by the flavor of the vegetable so much and named it komatsuna, after the nearby Komatsu River[2] (which gives the village its name). Till this day, the Shin-Koiwa Katori Shrine offers komatsuna to the deities on New Year's Eve. People who come to the shrine to pray on New Year's Day are also given komatsuna for good luck in the new year.

Since the days of the shogun, komatsuna has been bred to have a sweeter taste. The old variety thought to have been served to the shogun is not widely available. That variety is called Goseki bansei. It grows faster and has bigger but fewer leaves than ordinary komatsuna, and a strong, spicy flavor.[citation needed]
