The WILDLIFE OF JAPAN includes its flora , fauna and natural habitats . The islands of Japan
Japan
stretch a long distance from north to south and cover a wide range of climatic zones . This results in a high diversity of wildlife despite Japan's isolation from the mainland of Asia
Asia
. In the north of the country, there are many subarctic species which have colonized Japan

from the north. In the south there are south-east Asian species, typical of tropical regions. Between these areas lies the temperate zone which shares many species with China

and Korea

. Japan
Japan
also has many endemic species that are found nowhere else.

BIRDS

Over 600 species of bird have been recorded in Japan
Japan
and more than 250 of these breed. A number of birds are endemic including the Japanese woodpecker (Picus awokera), copper pheasant (Syrmaticus soemmerringii) and Japan's national bird , the green pheasant (Phasianus versicolor). Several species are unique to the smaller islands including the Okinawa rail

(Gallirallus okinawae), Izu thrush (Turdus celaenops) and Bonin white-eye (Apalopteron familiare ). Most of the non-endemic birds are shared with China
China
but a few originate in Siberia or south-east Asia.

Large numbers of migrant birds pass through Japan
Japan
in spring and autumn including many waders . In winter, several sites are important for swans , geese and cranes .

REPTILES AND AMPHIBIANS

Japan
Japan
has about 73 species of reptile of which nearly half are endemic. Sea turtles and highly venomous but non-aggressive sea snakes including the black-banded sea krait occur in warmer waters around southern Japan. Venomous snakes include the mildly venomous tiger keelback , and the more venomous front fanged vipers the elegant pit viper , Okinawa habu , Tokara habu , hime habu and the mamushi . Many pitviper species, known as habus throughout Japan
Japan
are endemic to islands in the warmer Ryukyu Island chain however the mamushi (Gloydius blomhoffii) is found on the main islands. Non-venomous rat snakes found in Japan
Japan
are the endemic Japanese rat snake , Japanese forest rat snake , Japanese four-lined rat snake , and the king rat snake and beauty rat snake (subspecies Orthriophis taeniurus schmackeri) which in Japan
Japan
are found only in the warm Ryukyu islands but have much wider distributions on mainland Asia. Three species of odd-scaled snakes are present in the southern islands including the Formosan odd-scaled snake, Japanese odd-scaled snake, and the Amami odd-scaled snake . Lizards include many endemic skink species (especially in the southern islands), the viviparous lizard (found as far north as the island of Hokkaido), and the Okinawa climbing lizard (Japalura polygonata). Freshwater turtles found in Japan
Japan
include the endemic Japanese pond turtle , Ryukyu black-breasted leaf turtle . The Chinese box turtle is found only on the southernmost islands of Iriomote
Iriomote
and Ishigaki in its Japanese range.

At least two crocodilian species are known to have occurred in the recent geological past of Japan: the chinese alligator and Toyotamaphimeia .

There are over 40 amphibian species including the Japanese giant salamander (Andrias japonicus), one of the world's largest amphibians. The Asiatic salamander family (Hynobiidae) is particularly well represented; many members of the family are found only in Japan.

FISH

Over 3000 different types of fish have been recorded in Japan. Important freshwater fish include the ayu (Plecoglossus altivelis), crucian carp (Carassius carassius) and common carp (Cyprinus carpio). The common carp is the ancestor of the well-known domestic koi carp. Small freshwater fish include the pale chub , Japanese chub (Nipponocypris sieboldii) and several species of bitterling including the endangered rosy bitterling . The southern Ryukyu Islands are home to endemic species of colourful freshwater gobies in the genus Stiphodon .

Notable anadromous fish include six species of salmon represented by the chinook salmon , chum salmon , pink salmon , coho salmon , sockeye salmon , and the cherry salmon (which has several unique freshwater morphs in Japan). Chars in the genus Salvelinus are represented by the white-spotted char (including several unique varieties such as the Gogi char), Dolly Varden trout
Dolly Varden trout
, and the endemic Kirikuchi char . The Japanese taimen ( Hucho perryi ) is the largest fish to enter freshwater in Japan
Japan
and may reach sizes of up to 2 meters in length. The Japanese taimen is a critically endangered species including the Japanese populations which are restricted to the rivers and surrounding ocean of Hokkaido. Also present is the Japanese dace ( Tribolodon hakonensis).

Important saltwater fish include the red sea bream (Pagrus major). Mudskippers are found in warmer areas while coral reefs in the Ryukyu Islands have many fish typical of tropical waters such as parrotfish and anemonefish . The little-known goblin shark (Mitsukurina owstoni) and frilled shark (Chlamydoselachus anguineus) have been recorded from deep waters off Japan.

FLORA

" Jōmon Sugi ", a large and ancient Japanese red cedar on toyok .

Around 4000 to 6000 species of plants occur naturally in Japan. The vegetation varies widely from subtropical forest in the south to coniferous forest in the north. In the subtropical zone, mangroves , cycads and tree ferns can be found. In the warm-temperate climate of Kyūshū, Shikoku and south-western Honshū, the dominant vegetation is broad-leaved evergreen forest with many oaks . In north Honshū
Honshū
and south-west Hokkaidō
Hokkaidō
the climate is cool-temperate with broad-leaved deciduous trees including Japanese beech (Fagus crenata) and oaks like the konara (Quercus serrata). Conifers are dominant in much of Hokkaidō
Hokkaidō
and in the mountains of central and northern Honshū
Honshū
with spruces and firs growing. In the highest mountains there is a zone of Arctic–alpine
Arctic–alpine
plants including the low-growing Siberian dwarf pine (Pinus pumila).

Conifer plantations have replaced natural forest in many areas. Commonly grown trees include the hinoki cypress (Chamaecyparis obtusa), Japanese red pine (Pinus densiflora), Japanese black pine (Pinus thunbergii) and Japanese red cedar ( Cryptomeria
Cryptomeria
japonica). The last is Japan's tallest conifer reaching 40 metres in height.

Bamboo
Bamboo
grows abundantly in Japan
Japan
with around 400 to 500 different species including the dwarf bamboos known as sasa and the taller kinds called take which can reach 20 metres in height.

Many plants have been introduced to Japan

from mainland Asia including important crops like rice and garden plants such as the chrysanthemum . Since the Meiji Restoration , increasing numbers of plants have come from Europe
