Wasabi is an essential spicy source for some Japanese food such as sushi. However, do you know how wasabi is grown? In my hometown, Shizuoka, there is a place named Utogi, where wasabi was cultivated for the first time in Japan.
In 1 hour drive from Shizuoka station, after driving a winding road through mountains of Abe-Oku, we arrive at Utogi, which is in May surrounded by green colors including those of tea leaves.
And soon after we walk from Utogi village toward mountains, we can find many green plants grown on terraced fields.
Wasabi cannot grow without clean water flowing by the plant. Therefore, wasabi plants are always made along the river as terraced fields so that water from the river flow by the plant. The existence of wasabi indicates how clean water in the area is.
According to the history of Utogi, at the beginning of 17th century, when the Shogun of Tokugawa started Edo era, a man living in the village tried to plant wild wasabi on a spring and soon found that wasabi by flowing water grew much better. This is how Utogi people started growing wasabi.
In the village we can taste fresh wasabi with soba noodle. With the knowledge how to grow wasabi, it tastes more special.
