The Japanese cockroach (''Periplaneta japonica''), also known as the Yamato cockroach,〔 is a cockroach native to Japan that is adapted to cooler northern climates. It has a flexible univoltine or semivoltine (one or two year) lifecycle, depending on the timing of its hatching, and is unusual in being able to spend two winters as diapause nymphs before reaching maturity.〔 == Freeze tolerance == Nymphs have been observed in the wild hibernating in sub-freezing temperatures during winter months in snow-covered habitats. Overwintering nymphs were able to survive laboratory supercooling experiments in the -5 °C to -8 °C temperature range, enduring twelve hours of tissue freezing, as well as recover from burial in ice. The ability to walk on ice was also found to be unique among several cockroach species tested.〔
