Tsukaikoku
The Wajinden said Tsukaikoku island didn't have good farming land. But, Ōe Masafusa wrote there were places to grow crops. The island often gave soybeans as a gift. The records show the island had a lot of precious things. These included silver, lead, tin, pearls, gold, and lacquer. Pearls were especially important. But the pearls might not be real. They could be red paint made from a stuff called cinnabar. This stuff is found mixed with minerals in mountains...
