Miasa has a long tradition of producing hemp, which has been grown there since the Yayoi period, 2000 years ago.

It is part of a Sister City exchange program with Mendocino, California. Each year, the Junior High from one country sends students to the school at the other for a two-week visit, enriching understanding of the different cultures.
