Wakame Day (Wakame no Hi)

What Is Wakame Day?

Every year on May 5th is "Wakame Day." This anniversary was established in 1983 by the Japan Wakame Association. Tied to Children's Day, it aims to encourage people to eat plenty of wakame, which contains minerals such as calcium that are important for children's growth. The date was also chosen because wakame has close ties to children -- it is sometimes used in gifts celebrating a birth -- and because this is the season when the new wakame harvest comes in.

Wakame and Japanese Food Culture

Wakame is a type of seaweed deeply tied to the Japanese diet.

• An ancient food: Seaweed appears in poems in the "Man'yoshu," Japan's oldest surviving poetry anthology, and in the Nara period wakame was one of the seafood products presented to the imperial court.
• Ties to children: Wakame is sometimes used in gifts celebrating a birth, and has been regarded as a food associated with wishing for children's healthy growth.

Wakame's Nutritional Components

While eaten as an everyday food, wakame contains some notable nutrients.

• Rich in dietary fiber: Wakame contains soluble dietary fibers such as alginic acid and fucoidan.
• A mineral-containing seaweed: It contains minerals such as calcium, magnesium, and iodine.
• Low in calories: Both dried and fresh wakame are low in calories, and are often used in soups and side dishes.

Wakame Production and Distribution

• Main production areas: In Japan, the Sanriku coast and the Naruto Strait are well-known major wakame-producing regions.
• Mainly farmed: Most of the wakame on the market today is produced through aquaculture.
• Processing forms: Wakame is distributed in various forms depending on shelf life and use, including fresh, salted, and dried wakame.
