Invasion information | ||
Range in Japan | Okinawajima Is., Amamioshima Is., and mainland of Kagoshima Pref. (Kiire area, Kagoshima City). In 2012, this species occurred in Satsumasendai, Kagoshima Pref., where whether the mongoose is established or not is unknown. The eradication of the established population in Amami-Oshima was achieved in 2024 by the eradication project of the Ministry of the Environment. |

Origin | From river mouse of Ganges River to Okinawajima. From Okinawajima to Amamioshima. Origin of the Kagoshima mainland population is unknown. | |
Date | Okinawajima Is.: 1910; Amamioshima Is.: 1979; Kagoshima City: 1980 or earlier | |
Route | Deliberate: In Okinawajima Is., introduced for biological control of rats and the pit viper (Protobothrops flavoviridis). In Amamioshima, possibly for biological control of the pit viper. Unknown for mainland of Kagoshima where P. flavoviridis do not occur. | |
Impact | Actually: Predation on various small terrestrial animals. Damage on agriculture. Potentially: Zoonosis. Leptopiruria was actually carried by Okinawa population, and Canine madness was carried by Antilles populations. Native organism(s) affected: Various small terrestrial animals such as Small mammals, birds, reptiles, amphibians, and insects, including many endangered and endemic species (Pentalagus furnessi, Diplothrix legata, Tokudaia muenninki, T. osimensis, Crocidura watesei, Gallirallus okinawae, Garrulus lidthi, Luscinia komadori, Ateuchosaurus pellopleurus, Odorrana narina, O. amamiensis, O. ishikawae, O. splendida, Babina holsti, B. subaspera, Limnonectes namiyei, etc.). Some of these species have exhibited population recovery after control of mongoose. In contrast, the mongoose may not be effective for control of the pit viper. Damages on chicken farming, banana, mango, citrus, etc. | |
Regulation in Japan | Import, transport and keeping are prohibited in Japan by the Invasive Alien Species Act. | |
Introduced range in other countries | Bosnia and Herzegovina, Croatia, Cuba, the Dominican Republic, Jamaica, Puerto Rico, Surinam, Hawaii, Fiji, etc. |

100 of the World's Worst Invasive Alien Species, 100 of the Japan's Worst Invasive Alien Species Recent molecular systematic studies suggested taxonomic changes of this species and genus. According to these studies, the invasive populations should be placed in Herpestes auropunctatus (“Small Indian mongoose”, rather than “Javan mongoose”). |
