The world's largest hornet's nest is an artificially created composite nest, in the shape of Mount Fuji, composed of 160 normal nests joined together by sculptor Yoshikuni Shiozawa from Nagano, Japan. It measures 4.8 m wide at its base, stands 3.766 m high, and contains an estimated 160,000 hornets, which are Japanese yellow hornets Vespa simillima xanthoptera. This is a subspecies of the yellow hornet, and is often preyed upon by the closely related but much larger Japanese giant hornet V. mandarinia japonica.
Shiozawa is the owner of a hornet museum named 'Hachi-Tengoku', Paradise for Hornets, and has created three previous hornet sculptures. All the hornets inside the combined nests live together without conflict as one giant hive. He likes to demonstrate that hornets don't sting blindly, using his own body as a test subject.
