Commentary: Book Ten Poems of Celebration 626

Headnote: "Composed among five poems of celebration, when the Regent, then Minister of the Right, had hundred-poem sequences composed"
Composed among five poems of celebration when Kujō Kanezane, Regent at the time this anthology was compiled, was still Minister of the Right and had people compose hundred-poem sequences. Even if Urashima should come home a hundred or a thousand times, he says, Mount Hakoya will surely remain evergreen. Urashima is the legendary figure who found, on returning from the palace of the sea god, that long years had passed in his homeland. The poem says that even after the immense span of years in which Urashima might return a hundred or a thousand times, the retired emperor's palace will flourish unchanged, and so celebrates his long life. The sequences are those of the Minister of the Right's house in 1178.
The author, "Shunzei, Master of the Empress Dowager's Household," was the son of Provisional Middle Counselor Fujiwara no Toshitada. He served as Master of the Empress Dowager's Household, later took the tonsure under the name Shakua, and compiled this anthology at the command of Retired Emperor Go-Shirakawa.
Like the preceding poem, 625, this poem sings of Mount Hakoya, so that two poems celebrating the retired emperor's palace follow one another. The preceding poem sings of its eternity through the shade of the pine, this one through the legend of Urashima.

First line, "momochitabi": "a hundred or a thousand times," countless times.
Second line, "Urashima no ko wa": Urashima is the legendary man invited to the palace of the sea god who, on returning home, found that long years had passed.
Third line, "kaeru tomo": "tomo" is a concessive conjunctive particle, "even if he should return."
Fourth line, "Hakoya no yama wa": the palace of the retired emperor. It is the same as the fourth line of the preceding poem, 625.
Fifth line, "tokiwa naru beshi": "tokiwa" means eternally unchanging, and "beshi" is conjectural, "it will surely remain unchanged forever." It echoes "tokiwa naru" in the first line of 640, the last poem of the book.
