Japan’s sea grapes are a type of seaweed that resembles fish roe (eggs) and is considered a very healthy and delicious addition to a meal.
The Japanese word “umibudo” literally translates into English as “sea grapes” and although this is not the technical name for this plant, it is much easier to remember than its scientific name. The plant gets its name from the little round balls attached to the stem of the plant.
Despite its name this plant is not actually a bunch of grapes growing in the sea, but rather it is a form of seaweed that simply resembles miniature grapes. However, it should not be confused with the seagrape tree found in the Caribbean.
Although you may not have seen sea grapes outside of Japan they are still widely known for being a delicacy and are not only a great addition to many Japanese meals, but they also carry many health benefits.
Here we do a deeper exploration about Japanese sea grapes from where to find them to how to prepare them and their health benefits.
Where can I find Japanese sea grapes?
Japanese sea grapes are mostly harvested in the tropical southwest islands of Japan. Seagrapes are typically found in abundance here as they need mild water, shallow sea floors, and sand in order to be able to grow.
The sea grapes require a water temperature of around 25 degrees celsius to grow and this is exactly the average temperature of the water around Okinawa.
Due to its growing popularity, sea grapes, although traditionally harvested from the ocean, are now farmed. This is to help control the number of sea grapes in the natural habitat and to stop overharvesting, which was quickly becoming a problem.
Buying seagrapes in Japan
If you’re looking to find sea grapes to eat then the chances are that you are not going scavenging in the ocean near Okinawa. Instead, you are in luck if you live in mainland Japan.
Japanese sea grapes have become so popular over the years that they can now be found in most Japanese supermarkets. Izakayas (Japan pubs) commonly serve seagrapes as a topping on many traditional Japanese dishes.
At many grocery stores across Japan, you will usually find the sea grapes packaged as a dehydrated snack in brine. The reason why you may struggle to find fresh sea grapes is that their shelf life is very short and so they will not transport well from remote Okinawa.
If you do buy the dehydrated sea grapes don’t despair as they can easily be rehydrated and return to their original state. To do this simply leave them in water for a few minutes.
Not only is Umibudo a delicious snack but it also has some great health benefits. Like many other forms of seaweed, umibudo is associated with a boost in skin health. This is thanks to the different minerals that can be found in the sea grapes such as magnesium, calcium, iron, and even iodine.
