The direct route refers to, in later years, a famous route to cross Mt. Ikoma (Tadagoe no michi Route), but in the case of Oe no izahowake no mikoto, as he was trying to go over the mountain via the Hanyu-zaka Pass (Habikino Hills), the route is thought to be somewhere around the present-day Anamushi-toge Pass.
直越えとは、後世、生駒山を越える道（直越道）が有名であったが、埴生坂（羽曳野丘陵）から越えようとしているので、現在の穴虫峠付近と考えられる。
