About the color of tosaka-nori

There are three types of Tosaka-nori: white, green, and red, but they all come from the same Tosaka-nori seaweed. Originally, Tosaka-nori is vivid red in color, but its color changes during processing. No artificial coloring is used, and there is no difference in the type of Tosaka-nori used, regardless of its color.

  • Aka Tosaka

    We sun-dry it to achieve a brighter red color.

  • Ao Tosaka

    We use limestone for alkaline processing to achieve a beautiful green color.

  • Shiro Tosaka

    We repeat the alkaline processing with limestone to bleach it, resulting in a white color.
