This report discribes the " Tsudureko Odaiko matsuri" (the great drum festival), an annual event of the Tsudureko Shrine in Takanosu City, Akita Prefecture. There are three of the huge barrel type drums, "Tsudureho Odaiho", that appear in the event. One of the drums registered in Guinness Book of Records. This drum has a diameter of 3.71 meters. The tub-shaped bodies of these drums are made of cedar (Akita Sugi). The wood for these is twisted and bound with bamboo bands. Cowhide is used for the membranes (drum-heads) of the drums.
