What is Okinawa’s specialty “Umibudo”?
One ingredient you absolutely must try in Okinawa is “umibudo (sea grapes)”.
It gets its name because it looks like small green grapes,
but it is actually a type of seaweed.
Its distinctive texture, which pops in your mouth,
has earned it the nickname “green caviar.”
As a local Okinawan dish,
the classic way to eat it is simply dipped in ponzu.
It’s also popular as a topping for salads and seafood bowls.
You can easily find it at restaurants and markets in Okinawa,
so be sure to try it when you visit!
Characteristics and Appeal of Umibudo
1. The addictive popping texture!
The biggest characteristic of umibudo is its “popping” texture.
When you bite it, it lightly bursts in your mouth and a subtle ocean flavor spreads.
2. Low-calorie, healthy superfood
Umibudo is a low-calorie, mineral-rich healthy ingredient.
It’s perfect for people on a diet or those focused on beauty and wellness.
The main nutrients it contains include:
✅ Minerals (calcium, magnesium, potassium) – help maintain body balance
✅ Seaweed-derived dietary fiber and sulfated polysaccharides – components expected to support immunity and health
✅ Vitamin C – good for the skin
3. A fresh seaweed eaten alive
Umibudo will shrivel without moisture,
so it is usually sold kept in saltwater.
In Okinawa you can eat very fresh umibudo,
so be sure to experience its juicy, fresh texture!
