The name “Yotsuhō” for this coin comes from the poor quality of the Hōei Yotsuhō silver coins, which were unpopular. Because of their poor quality, they were called Yotsuhō coins.
It was long believed that they were made during the Hōei period, but recent excavations have shown that they date back to the Genroku period.
This page references “Anasen Nyumon Kanei Tsuho – new Kan’ei Tsuho -,” so we will introduce it as Yotsuhō Sen.
