Jellyfish most are nowhere near that large). They have a moderately painful, but rarely fatal, sting. The increasingly common giant Nomura's jellyfish, "Nemopilema nomurai", found in some, but not all years in the waters of Japan, Korea and China in summer and autumn is another candidate for "largest jellyfish", in terms of diameter and weight, since the largest Nomura's jellyfish in late autumn can reach in bell (body) diameter and about in weight, with average specimens frequently reaching in bell diameter and about in weight. The large bell mass of the giant Nomura's jellyfish can dwarf a diver and is nearly
Nomura's jellyfish resource. The Japanese company Tango Jersey Dairy produces a vanilla and jellyfish ice cream using Nomura's jellyfish. Consuming echizen kurage is potentially dangerous if the toxic part is not thoroughly cleaned and cooked. One study sought to use the mucin of the Nomura’s jellyfish to treat joint disease such as osteoarthritis. Like many invasive species, such as the cane toad, a simple solution is to take the species and convert them into fertilizer. Another study aimed at using an aqueous menthol extract of dried medusa to inhibit the growth of weed seedlings when added to soil. Nomura's jellyfish The diameter
