speciesfound in Japanin the Ryukyu Islands. No subspeciesare currently recognized.ITIS|ID=634913|taxon="Trimeresurus flavoviridis"|year=2008|date=25 July]
Grows to an average length of 4-5 feet (122-152 cm). With a maximum of 7.5 feet (229 cm), it is the largest member of its genus. Slenderly built and gracefully proportioned with a large head. The tail, however, is not prehensile.
Scalation includes 35 (sometimes 31, 33, 37 or 39) rows of
dorsal scalesat midbody, 217-239 ventral scales, 72-95 subcaudal scalesand 7-10 supralabial scales. The crown is covered with small scales.
The color pattern consists of a light olive of brown ground color overlaid with elongated dark green or brownish botches. The blotched have yellow edges, sometimes contain yellow spots, and frequently fuse to produce wavy stripes. The belly is whitish with dark coloring along the edges.

Japanin the Ryukyu Islands, including Okinawa and the Amami Islands. The type locality given is "Amakarima Island (one of the Loo-Choo group)" (= Keramashima, Ryukyu Islands).
Oviparous, it is one of the few pitvipers that lays eggs. Mating takes place in early spring and up to 18 eggs are laid in mid-summer. The hatchlings, which emerge after an incubation period of 5-6 weeks, are 10 inches (25 cm) in length and look the same as the adults.
To reduce the population on the island of
Okinawa, the small Indian mongoose, " Herpestes javanicus", was introduced in 1910. Although the effects of this introduction have not been studied, in other such cases the negative effects on species of native birds, mammals, and herpetofauna have been a source of concern for wildlife managers.Hays WST, Conant S. 2007.

The incidence of snakebite in the
Amami Islandsis 2 per 1,000 people, which is very high. Fortunately, the venom of this species is of a relatively low toxicity with a fatality rate of only 3%. However, 6-8% do suffer permanent disability.
