This spider is a real, taxidermy Nephila Maculata spider, otherwise known as the Giant Wood spider. Nephilas are members of the golden orb weaving family, spinning webs out of yellow thread that measure a meter wide. They are known as the biggest spider in Japan, where they are called "O-jyorou gumo". Gumo meaning spider, and O-jyorou meaning Femme Fatale. They are docile yet poisonous. It said that seeing one in the daytime can bring good luck, but seeing one at night will do the opposite.
