The Grave of Toribeno refers, in the past, to the lands east of the Gojyou-oohashi (The Great Bridge of Gojyou), which were left undeveloped and apparently were used for burial purposes. At the same time, as travel to and from the far-reaches of Japan required passing through this land, this area could be considered the land of Watanabe. Wataru, one of the root words for Watanabe, means "pass by", "pass through", "cross" or "traverse". Hence Watanabe can be interpreted as "the area through which you pass". It could be that the ancestors of the Watanabe clique once used to live at that spot, protecting the threshold of the Gasaraki Ceremony.
