Distribution
The genus Fukuia is endemic to Honshu, Japan.[2] These snails occur especially in the northern and western part of Japan, on the coast of the Sea of Japan.[2] There is a unique climate in the Sea of Japan with high precipitation due to winter snowfall in the area of distribution of Fukuia.[2] These snails have been described as a "Japan Sea element".[2]

Species
Species within the genus Fukuia include:
- Fukuia integra (Pilsbry, 1924) - synonym: Blanfordia integra Pilsbry, 1924, terrestrial[2]
- Fukuia kurodai Abbott & Hunter, 1949 - type species,[3] amphibious[2]
- Fukuia multistriata Abbott & Hunter, 1949 - amphibious[2]
The speciation of genus Fukuia likely started around 7.2 million years ago in the Late Miocene.[2]
Unassigned to genus:
- Fukuia ooyagii Minato, 1982 - Aquatic species Fukuia ooyagii should be separated from Fukuia, and its generic assignment should be determined coupled with the investigation of its soft-part morphology.[2]

Ecology
Fukuia kurodai and Fukuia multistriata live amphibiously around rocky walls of steep valleys covered with ferns and bryophytes, and moistened by dripping water.[2] They live only along the mountain streamlets where such habitats are typically found, and often occur with pleurocerid freshwater snails.[2]
Fukuia integra lives as a terrestrial snail in inland forests.[2]
