Akihiro Hino
Professor Layton is based on the idea of an English gentleman, and is a professor of archaeology at the fictional Gressenheller University in London. He was designed by Level-5 CEO Akihiro Hino, who used Sherlock Holmes and fellow video game character Phoenix Wright as inspiration for his creation. He is voiced by Yo Oizumi in the original Japanese releases of the series, and by Christopher Robin Miller in English-language releases.
