My name is Haruhiko Maruyama from the Department of Parasitology, Department of Infectious Diseases, Faculty of Medicine, University of Miyazaki. I have been appointed as Chairman of the Japanese Society of Parasitology. This year marks the 100th anniversary of the Tokyo Society for Parasitology (1921), the predecessor of our current Society.
I joined the Society in 1986. Over the past 35 years, parasitology has seen significant changes: the advent of molecular biology, genomic data, and advanced analytical techniques have deepened our understanding of parasites at molecular and cellular levels. Diagnostic technologies have become commonplace. Meanwhile, infectious diseases have become globalized, crossing borders with ease.
Going forward, I wish to promote the Society’s activities from three perspectives: parasitology as basic science, practical science, and even as a source of curiosity or pastime.
As a basic science, parasitology allows us to ask fundamental questions: Why and how do parasites choose specific hosts or organs? Deeper knowledge of parasites leads to deeper understanding of ourselves.
In practical terms, parasitology contributes to diagnostic developments, infection control, surveillance, vaccine development, and antiparasitic drugs. It is vital to respond promptly to real-world clinical needs. Parasitic diseases remain significant within neglected tropical diseases globally. I hope Japanese parasitology will contribute to achieving universal health coverage (UHC).
Some may object to the idea of parasitology as entertainment. But parasites frequently appear in popular media, and general books on the subject remain well-read. This shows there is a real public interest. It is our duty to convey the mystery and wonder of parasites through outreach and education.
In the fantasy novel The Twelve Kingdoms by Fuyumi Ono, the quote: “Your job is what you choose. Your role is given by God.” resonates with me. I believe my role as President was given to me by a divine parasite. I will do my best to advance the Society’s contributions to science and society.

With gratitude, May 2021
