Mauremys japonica
A geoemydid turtle endemic to Japan, with a flattened orange-brown to dark brown carapace reaching 21 cm in females and 14.5 cm in males. It favours clean, gently flowing water and is notably cold-tolerant.
Mauremys japonica is endemic to Japan, ranging from Honshu south of Akita and Miyagi prefectures through Shikoku, Kyushu and the surrounding islands. The carapace reaches 21 cm; females grow larger, while males stop at 14.5 cm at most. Carapace colour varies widely from orange-brown to dark brown, the vertebral scutes carry an interrupted keel and the rear marginals are slightly serrated, while the plastron is usually a solid black or dark brown. It prefers gently flowing water and cleaner conditions than the Reeves' turtle. It is markedly cold-tolerant, having been seen active at water temperatures of 3-5 C. An omnivore, it eats fish, amphibians, crustaceans, snails and aquatic plants. From June to August it lays one to 12 eggs per clutch, one to three times a year, hatching in about 70 days. Habitat loss, over-collection and genetic introgression from Reeves' and Chinese stripe-necked turtles have reduced it, and it is listed as Vulnerable on Japan's national Red List.

Nomenclature follows global taxonomic authority databases.
Listed in CITES Appendix II in 2013. Since it is listed in Appendix II, registration as an internationally endangered species is not required. Ministry of Environment Red List assessment is Vulnerable (VU). This species does not qualify as a designated animal specified in the Cabinet Order for the Law Concerning the Protection and Management of Animals. Individuals resulting from hybridization with the Asian pond turtle are designated as designated alien species.

Prepared pellets, small fish, shrimp, snails, insects, aquatic plants and fruit
A Japanese native with strong cold tolerance, it will hibernate naturally in an outdoor pond. Indoors, combine supplementary heating with a dry land area where the skin and shell can dry completely, under lighting that includes ultraviolet.
Keep it in an aqua-terrarium. It is sensitive to poor water quality, and frequent changes with unconditioned tap water often bring on fungal skin disease. Stabilise conditions with a generous water volume, effective filtration or green water. If kept in an outdoor pond, guard against escapes.
Omnivorous and readily converted to prepared pellets in captivity. Vary the diet with small fish, shrimp, snails and greens. Large wild-caught adults can be reluctant to start feeding.
Many individuals are wary and will slide into the water at the sight of a person while basking. Avoid unnecessary handling and provide a basking area and hides where it can settle.
Listed on CITES Appendix II in 2013, so no Japanese registration certificate is required, and assessed as Vulnerable on Japan's national Red List. It hybridises with Reeves' and Chinese stripe-necked turtles, so do not house it with other species; hybrids with the Chinese stripe-necked turtle are designated invasive alien species in Japan. Never release or abandon animals outdoors, which spreads genetic introgression. Juveniles are sometimes sold under the trade name zenigame, but in recent years that name has usually referred to juvenile Chinese pond turtles, a different species. A label reading simply ishigame may likewise refer to the Asian yellow pond turtle, so confirm the scientific name Mauremys japonica when buying.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Japanese Pond Turtle is 15-25 years. With proper care and nutrition, they can live a long and healthy life.
Japanese Pond Turtle typically reaches Carapace up to 21cm in females and 14.5cm in males as an adult. Size may vary depending on care conditions and individual genetics.
Japanese Pond Turtle feeds on: Prepared pellets, small fish, shrimp, snails, insects, aquatic plants and fruit. Aim for a balanced diet with appropriate feeding frequency.
