Spring is here. A time for cherry blossoms, baseball and, in Japan, eating wild plants from the mountainside.
Sansai, which literally means mountain vegetables, are the young tender buds and shoots from wild plants found in the mountains. The best time to gather sansai is April and May. After that, the plants grow out of control and are no longer tender and tasty.
For centuries, Japanese have harvested these wild plants. Although no longer a necessity for survival, sansai are still cherished by many. And recipes for these wild weeds have been passed on fromgeneration to generation.
Sansai are usually succulent, tender, a little bitter, and have a strong lye, which means they need some preparation before cooking. Different sansai require different ways to take out the lye and prepare. Once they are prepped, they can be used for tempura, a topping in soba noodles, stir-fried or marinated with other vegetables.
Some of the popular sansai are taranome (aralia sprout), zenmai (royal fern), warabi (bracken), kogomi (ostrich fern) and fukinoto (Japanese butterbur).
My favorite way to taste sansai is tempura, especially taranome tempura, which has a crunchy yet tender texture and contains a slight sweetness from its young buds.
It is believed that sansai are highly nutritious and are a natural medicine that can help fend of various diseases.
On Okinawa, because of its tropical weather, sansai are not commonly known as a seasonal specialty. However, sansai played a vital role in wartime, according to Junichiro Higuchi, arborist and a sansai guide on Okinawa.
“During World War II, many Okinawan people escaped to Yambaru in the northern part of Okinawa,” Higuchi said. “They did not have enough food because they were hiding in the mountains. So, they used to eat edible wild plants to survive.
“Many old Okinawans know how to eat sansai in the wild, but most young people now don’t know about sansei,” he said. “But, there are many sansai that you can find on Okinawa.”
In Japan, most mountains are privately owned. In other words, you can’t just go in there and take the plants. It is also prohibited to take plants from national parks and nature reserves. So it is difficult for people to find sansai in the mountains nowadays.
“It used to be a common thing to pick sansai and share with your family and community,” said Gohei Murakami, director of the Japan Special Forest Product Promotion Association. “But urban development shrunk up the mountainside and the tradition of eating sansai has decreased recently, especially among young generations. Today, most people don’t know how to find sansai in the wild.”
You can always go to a super market. However, Murakami pointed out that sansai sold at super markets are ones that are likely grown on a farm. He also said the taste could be a tad weaker.
“Probably, the best place to purchase naturally grown sansai would be a farmers market in the countryside that is run by JA (National Federation of Agricultural Cooperation of Associations),” said Murakami. “Some sansai are in the risk of radiation exposure from Fukushima nuclear power plant, so it is recommended to purchase the product which are officially inspected by JA.”
JSFPPA has been holding workshops to teach people about sansai and how to sustain it. There are currently about 70 certified sansai advisors in Japan who spread the goodness about these wild plants.
“Our ancestors tried and tested so many wild plants to distinguish if those are edible or not, tasted or not, and passed the recipes on to us,” said Murakami. “It is a joy of spring. The tradition of tasting sansai is a wisdom that we would like to hand to next generation in Japan.”
