Dr. Hayashi was featured in the opening interview of the Koishikawa local edition of "Chikyu no Arukikata" (How to Walk the Earth), a well-known Japanese travel guidebook series.

His hidden passion for walking through neighborhoods, combined with his work in data analysis, came together in an unexpected way to lead to this opportunity.

If you come across a copy at a bookstore or around the Koishikawa area, we hope you will take a look.
