Apis cerana japonica is a subspecies of the eastern honey bee native to Japan. It is commonly known as the . This subspecies was determined, through an analysis of mitochondrial DNA, to have originally come from the Korean peninsula. They have been observed moving into urban areas in the absence of natural predators. A. c. japonica is very resistant to the mite Varroa jacobsoni, which is commonly found among A. cerana. It is also able to adapt to weather extremes, has a long flight duration and is less likely to sting than the western counterpart. 3-Hydroxyoctanoic acid is a signalling chemical emitted by the orchid Cymbidium floribundum and is recognized by Japanese honeybees. Use in apiculture Beekeepers in Japan attempted to introduce western honey bees (Apis mellifera) for the sake of their high productivity. However, western honey bees have no innate defense against Asian giant hornets, which can rapidly destroy their colonies. Japanese honey bees, having evolved alongside the Asian giant hornet, have numerous defensive strategies against the hornets and so are also used in apiculture in the country. Hive Nest cavity ranges from 10 to 15 liters with a round comb structure that tends to be uneven. A. c. japonica will also dismantle an old hive before moving on to a new one. Pollination A. c. japonica pollinates the endangered orchids Cymbidium kanran and Cymbidium goeringii despite not having nectar for the bees to collect, instead releasing pheromones used to orient forager bees returning to the hive as a deception tactic in order to be pollinated. Dancing A. c. japonica, like many other honey bees, dance in order to inform nestmates of locations for "effective flower resources". However, unlike other honey bees, they do not dance for the location of propolis. A. c. japonica also perform short waggle dances after their nest has been scouted by hornets or other competing bees in addition to hive smearing to facilitate the protection of the nest. Protective behaviors When threatened by hornets or other competing honey bees, A. c. japonica will dance and smear plant material at the entrance of the hive. A threat consists of a hornet or competing bee arriving to the home nest and scouting it, smearing it with pheromones. Performing the dance triggers an emergency, bees will travel a short distance to gather plant material. A. c. japonica does not discriminate between plant texture, color, or the part
