Giant Tohoku (GT) rollers are so named due to their larger size compared to other rolling pin floats. The standard length of both Tohoku and Hokkaido rollers is approx 6". Of course there are variations of that size however, 6" seems to be the normal length. GT rollers measure 9.5 inches. With all rollers, the length can vary due to the perfection of the glass blower.Giant Tohokus come from the Tohoku region of northern Japan. They are extremely hard to find in the field. In mainland Japan, most of the old fishing shacks have fallen and been replaced with new ones. In the process, the floats were discarded and have since disappeared. Although roller floats are still used in Hokkaido, they are long gone from the ports in northern Japan.
