Gyoja garlic is a wild mountain vegetable known for its strong aroma and flavor, which are reminiscent of garlic. Its Japanese name is traditionally said to come from gyoja, the mountain ascetics who practiced rigorous religious training in remote mountain areas and are believed to have eaten the plant as a nourishing food.
Several regional varieties of gyoja garlic can be found across Japan. The native variety of the Shonai region is particularly distinctive for its well-formed appearance and the reddish color that develops on part of its stem. Because of its quality, it is also known as a popular mountain vegetable in markets in the Tokyo metropolitan area.
As its name suggests, gyoja garlic has a strong, garlic-like aroma and rich flavor. Its distinctive character can be enjoyed in a variety of ways, including raw, or prepared as soy sauce pickles, blanched greens, and tempura.
Marinating it in soy sauce creates a flavorful accompaniment to steamed rice, while deep-frying it as tempura adds a pleasant crispness and roasted aroma. It can also be simply blanched and served as an ohitashi, allowing its natural fragrance and flavor to take center stage.
In the Asahi area of Tsuruoka City, Yamagata Prefecture, efforts to cultivate gyoja garlic began more than 30 years ago. Local residents originally brought plants growing wild in the surrounding mountains back to their homes and began cultivating them.
Today, approximately 20 farming households in the area grow gyoja garlic, passing down the cultivation practices that have developed over the years.
Gyoja garlic is a slow-growing plant that is susceptible to insects and diseases, so producing it requires considerable time and effort. The plants must be carefully cultivated for many years before they are ready for harvest and shipment.
When the harvest season approaches, plants that have been dug up from the fields in autumn are moved into warm plastic greenhouses. By encouraging growth in the warmer environment, the plants can reach harvestable size in approximately two to four weeks.
In some cases, it takes around eight years from the beginning of cultivation until the plants are ready to be shipped. The long cultivation period makes gyoja garlic a particularly precious mountain vegetable, and it also makes the arrival of harvest and shipping season especially rewarding for growers.
The main season for gyoja garlic is April through June. In particular, during May and June, field-grown gyoja garlic becomes available, offering a particularly rich and aromatic flavor.
