Yoshizaki (in present-day Fukui prefecture) is well known for one of the places in the coastal region of Hokuriku (on the Sea of Japan), where Rennyo (1415-1499), the 8th abbot of Higashi Honganji, propagated Shinran's teaching.
The origins of this event is said to have started in 1752, when a group of priests and followers decided to walk 150 miles from Kyoto to Yoshizaki to bring the scroll of Rennyo's image to Yoshizaki Betsuin Temple for his memorial service in order to express their gratitude for his efforts to propagate in that area.
Since then, this event has continued to this day, when on April 17th every year, after the opening service at Amida Hall, the scroll is carried from Higashi Honganji in a mikoshi (a portable shrine) to Yoshizaki Betsuin Temple, to be present at Rennyo's memorial service from April 23rd to May 2nd. After the completion of this service, the scroll is then returned to Kyoto on May 9th in a similar fashion, whereupon the closing service at Amida Hall takes place.
