Shinji Ogawa explains, "Tokoroten is still a popular summer dessert in Japan. It is a jelly made from seaweed called Gelidium Amansii. Tokoroten is pushed through a coarse mesh to form long threads like Japanese noodles." Gelidium is a genus of red algae. Shinji adds that the phrase, koshi kakete, is an idiom for "sitting."
