I spent my childhood in Miyazaki, Kyushu, where both marine and freshwater organisms were abundant. I have been focused on the species diversity and evolution of gastropod molluscs (snails) since I was an undergraduate student. I have collected snails in various aquatic environments, from the north to the south, from freshwater streams to the deep-sea.

Natural history of amphidromous gastropods
Some freshwater animals are known to spend part of their life cycle in the sea. In the phylum Mollusca, some species of gastropods have amphidromous life cycles; their larvae are swept downstream to the sea and settle at the river mouth after a marine planktonic phase, and the juveniles then migrate upstream. Amphidromous neritid gastropods are relatively abundant in streams of the tropical and subtropical islands, including the Nansei Islands, Japan. The taxonomy of freshwater neritid gastropods is confused because their shells often show considerable intraspecific variation despite their high species diversity. I have studied the natural history of freshwater neritids, including taxonomy, larval ecology and evolutionary systematics, to clarify their species diversity and distribution in the Indo-West Pacific. 
Species diversity of deep-sea gastropods
In the northwestern Pacific Ocean around Japan, there are many deep-sea trenches, which are long and narrow depressions with steep sides. The hadal zone mostly exists in oceanic trenches (at depths of 6,500 m or deeper), which have extreme environmental conditions, including high hydrostatic pressure, total lack of sunlight and low food availability. The fauna of trenches is therefore characterised by lower abundance and species richness than that of the shallower zone. However, our understanding of hadal faunas remains fragmentary due to insufficient sampling in each hadal trench. I have participated in deep-sea cruise expeditions to collect gastropod molluscs by trawling in the Kuril-Kamchatka Trench and the Japan Trench at depths ranging from 6,500 to 9,580 metres to study the species diversity and evolutionary history of deep-sea gastropods in the hadal trenches.
