March 22 Special Program Details
Special Stage Show
A live stage show will be held on the day, bringing together three acts:
Basketball performer ISSEI
OZK Dance School, a kids' dance troupe active in the local Sennan and Hannan area
Slinky juggler Sasaman
Free Oyster Soup (First-Come, First-Served)
Plump oysters served in a flavourful broth will be available free of charge. A variety of ingredients will be included in the soup alongside the oysters. Quantities are limited, so arriving early is recommended.

Local Sake Tasting
A monthly highlight of the Sennan Oyster Festival, the local sake tasting returns with five carefully selected varieties of Japanese sake. Each cup is priced at ¥300 (tax included) or ¥500 (tax included) depending on the selection. Hot sake (atsukan) is also available. Valid photo ID confirming age is required for purchase.
Oyster Shell Recycling Workshop
Visitors can take part in a workshop using recycled oyster shells to create an original oyster shell candle—a hands-on souvenir to commemorate the day.
Food Rally and Prize Lottery
A stamp card is available at the entrance on the special event day. Stamps are collected by purchasing food from festival vendors, and a completed card can be entered into a prize lottery with the chance to win premium items.
