Commentary
Book Ten Kagura Songs 599

Headnote continued from the preceding poem: "Fūzoku songs for the Great Thanksgiving Festival of the first year of Anna: Mount Nagara"
The poem celebrates the long endurance of the emperor's reign, saying that like the name of Mount Nagara it will last long and be joyful. The headnote is the same as that of the preceding poem, 598, with Mount Nagara as its topic. The upper verse, "Nagara no yama no," leads into "nagaraete" of the same sound, tying the place name directly to the reign's endurance.
The headnote, "Fūzoku songs for the Great Thanksgiving Festival of the first year of Anna," shows that the poem was offered at the Great Thanksgiving Festival held in the first year of Anna upon the accession of Emperor Reizei. At this festival, poems working in the place names of the provinces chosen as Yuki and Suki were offered, and from here to 608 poems follow whose topics are the names of mountains and shores in those provinces.
The author, Ōnakatomi no Yoshinobu, served as chief priest of the Ise Shrine and, as one of the Five Men of the Pear Chamber, took part in compiling the Gosenshū. He is counted among the Thirty-Six Immortal Poets.

First line, "sazanami no," is a pillow word modifying place names in Ōmi Province.
Second line, "Nagara no yama no," means "of Mount Nagara" in Ōmi, and up to here the lines form a preface leading to "nagaraete" of the same sound in the third line. It sings of the same mountain as the second line of the preceding poem, 598, "Nagara no yama no."
Third line, "nagaraete," means "lasting long."
Fourth line, "tanoshikaru beki," means "bound to be joyful," with "beki" the attributive form of "beshi," expressing what is fitting.
Final line, "kimi ga miyo kana," means "our sovereign's reign," with "kana" exclamatory. It answers the first line of the preceding poem, 598, "kimi ga yo no."
