“Daikonjima” means radish island. Early farmers in the area chose the name deliberately to discourage outsiders from visiting the island and trying to steal its Korean ginseng crop. The black volcanic soil of the island is rich in nutrients and perfect for growing ginseng as well as other valuable crops.
Daikonjima Island is located in the middle of Lake Nakaumi in the eastern part of Shimane prefecture. It was formed by lava flows from Otsukayama shield volcano around 200,000 years ago. Farming on the island didn't begin until about the Edo-period. The ginseng produced by Daikonjima is among the highest quality in the world and is exported at a premium. The major drawback of ginseng is that it requires 5 or more years before it can be harvested. In order to generate income in the interim period, Daikonjima’s farmers grow and sell peony flowers and other fruits and vegetables, and take advantage of the fresh fish Lake Nakaumi offers up.

Daikonjima, in addition to the ginseng and peonies, offers locally grown “nijuseiki” pears, Saijo persimmons, figs, sea vegetables, ginger, coriander, Izumo soba buckwheat (used to make noodles), and many other healthy offerings.
Depending on the time of year, the waters of Lake Nakaumi, and the nearby Lake Shinji and Sea of Japan offer up a wide variety seafood.

Tai-meshi (steamed red snapper meat mixed with rice), suzuki no hoshoyaki (baked sea bass), and saba no shiokara (salt spiced mackerel) are just some of the savory traditional dishes to choose from.
