Since ancient times, Futamiura has been a place for purification before visiting Ise Jingu. There is a custom of giving Mukushioruo to visitors who cannot bathe, and in this ritual, seaweed used as material is collected. Priests board a boat adorned with Sakaki and Nobori, cut seaweed by hand sickles at sea, offer them, and after drying, make Mukushio Taima. (In case of rain: The event is generally held, but since it's a boat event, please confirm） Event: May 21 every year 10:00-11:00 AM Venue: Futamiokitama Shrine
