Biography Hikida was born in Usuki, Ōita Prefecture, Japan, in 1951. He graduated from the Faculty of Science, Kyoto University, in 1974, and completed coursework for the doctoral program at the Graduate School of Science, Kyoto University, in 1979 without submitting a dissertation.

From 1979 to 1995, he served as an assistant in the Department of Biological Sciences, Graduate School of Science, Kyoto University. He was later promoted to associate professor and then full professor, retiring from Kyoto University in 2016.

Research and career Hikida developed a fascination with nature from an early age, often collecting small animals and insects as a child. As an undergraduate, he studied ecology, with his graduation thesis focusing on age estimation in wood mice (Apodemus speciosus) based on their teeth. Upon entering graduate school, he shifted his focus to the phylogeny of reptiles. Since then, his research has centered on the systematics, taxonomy, and biogeography of reptiles.
