In view of the record in the Nihonshoki that Oku no himemiko became an Ise Saigu (an unmarried princess serving at Ise-jingu Shrine) and went to Ise in great numbers around that time, there is a possibility that Tochi no Himemiko accompanied the touring group.
ちょうどそのころ大来皇女が伊勢斎宮となり伊勢へ群行したと日本書紀に書かれていることから、これに同行した可能性がある。
