Yoso ni mishi mayumi no oka mo kimi maseba tokotsu mikado to tonoi suru kamo

外に見し真弓の岡も君座せば
常つ御門と侍宿するかも

Roma-ji: Yoso ni mishi mayumi no oka mo kimi maseba tokotsu mikado to tonoi suru kamo
English Translation: Mayumi Hill, which once
I saw as far removed from me—
now that you dwell there,
I keep my watch through the night
as at your everlasting gate.
Meaning: Mayumi Hill, which I once looked on as no concern of mine—now that you dwell there, my lord, I keep watch through the night as at your everlasting palace.
Commentary: Book Two Elegies 174

Headnote continued from the preceding poem: "Twenty-three poems composed in grief by the attendants of the Prince's palace"
Mayumi Hill, once a place with no connection to him, is now where the prince lies, so the speaker keeps night watch there as at an everlasting palace, a poem on how the place of service has changed.
According to the headnote, these are twenty-three poems composed in grief by the attendants who served in Prince Kusakabe's palace. A left note, citing the Nihon shoki, records that the prince died in the fourth month of the third year of Empress Jitō's reign (689). The sequence takes up, scene by scene, the laments of the attendants: the garden and ponds of the Shima Palace bereft of their master, and the night watches they kept on the hills of Mayumi and Sada where the prince lay in state. This is the fourth poem of the sequence.
The authors were the attendants who served in Prince Kusakabe's palace, and their individual names have not come down to us. Toneri were officials who served close to the Emperor and members of the imperial family as guards and aides. One theory holds that Kakinomoto no Hitomaro composed the poems in the attendants' voice, but this is not settled.

The first line, "yoso ni mishi," means "that I had looked on as unrelated to me."
In the second line, "mayumi no oka mo," Mayumi Hill is the place in Yamato where the prince's temporary shrine and tomb were built. It appears again in the twelfth poem of the sequence, 182.
In the third line, "kimi maseba," ba marks a condition fulfilled: since our lord dwells there.
The fourth line, "tokotsu mikado to," means "as the everlasting palace," referring to the tomb.
In the final line, "tonoi suru kamo," tonoi means staying overnight to guard, and kamo is exclamatory: so I keep my night watch.
