Rooted in a travelling mochi-pounding,it is a beloved year-end sight.

Gaito Mochitsuki is the first item on the city's list of designated intangible folk cultural properties. The city records that it traces back to woodworkers from the Awa region (now Tokushima) who came to Sunagawa in December 1899 and began pounding mochi free of charge around town at year's end, thinking of home. The Sunagawa Mochitsuki Preservation Society keeps it.
