Tokoroten
Tokoroten — chilled agar noodles cut from boiled Izu seaweed
Agarweed is boiled with water and vinegar, set in a mold, then pushed through a press into long strands. In the Izu peninsula, said to be the country's leading agarweed source, it was made at home and sold at candy shops alike, settling in as a children's treat.

What it's made of
Tokoroten is a jelly made by simmering tengusa seaweed in water with vinegar, straining the liquid, setting it in a mold, and pushing it through a special press into long thin strands. The Izu Peninsula is known for its tengusa harvest, and the texture is said to differ by variety: makusa, harvested in western Izu, gives a soft, sticky jelly, while obusa, harvested in eastern Izu, gives a thicker, firmer one.
How it's made
Tengusa seaweed is washed and simmered in water with vinegar. The liquid is strained, poured into a mold to set, then pushed through a press into long thin strands. It is typically topped with a vinegar-based sauce or soy-vinegar sauce, mustard, and shredded green nori, though it is also reportedly eaten sweet, topped with roasted soybean flour or black sugar syrup.
Why it took this shape
Tengusa harvesting on the Izu Peninsula reportedly goes back some 1,600 years, and the seaweed is said to have been used not only for tokoroten but also as fertilizer. Beyond being made at home, it was reportedly sold at neighborhood candy shops too, making it a fixture of childhood snacking. At Yagisawa beach in western Izu, spring and early summer are said to bring the sight of tengusa spread out to dry, covering the shore like a red carpet.
