I would say to them, come along.

Commentary: Book Twenty Poems of the Bureau of Court Song 1090

Headnote continued from the preceding poem: "Songs of the East: Michinoku Song"
If these lovely scenic spots were people, the singer says, he would take them back to the capital as a gift. It is a witty song that treats the landscape as a person and regrets that it cannot be carried home, praising the land.
The Michinoku songs are folk songs of the province of Michinoku, today's Tōhoku region, forming the group of seven from poem 1087 to 1093. They are provincial songs taken up into court performance.
Episode Fourteen of the Tales of Ise has "If the pine of Aneha in Kurihara were a person, I would say, come, as a gift for the capital," using the same lower lines.

The first line, "Ogurosaki," is a place in Michinoku, thought to be near Naruko in today's Ōsaki City, Miyagi. The original kana reads wokurosaki.
The second line, "the little isle of Mizu," names an islet in the river near Ogurosaki, listed alongside as a scenic spot.
The third line, "if they were people," sets up a supposition contrary to fact.
The fourth line, "as a gift for the capital," names what the landscape would become.
The last line, "I would say, come along," uses mashi for the counterfactual and o for a lingering, regretful turn.
