Some disagree with this by pointing out that the entrance of Ne no kuni (the land of the dead) Yomitsu Hirasaka was located in the former Izumo Province (Higashi Izumo-cho, Yatsuka-gun, Shimane Prefecture), thus it is odd to go all the way to Kii Province and "Ki no kuni" only means a place with many trees.
しかし、根の国（黄泉）の入口である黄泉津比良坂は旧出雲国(島根県八束郡東出雲町)にあり、一旦紀伊国まで行くのはおかしいとして、これは単に木の多い所の意味であるとする説もある。
