Thanks to GolSho I learned that the poem in question is https://100poets.com/2011/03/20/a-full-moon-night-poem-number-7/

(It's a poem written by a Japanese stuck in China as he wished to go home, but even if he started a journey home he was cast adrift and would end up never returning to Japan)

Japanese	Romanization	Translation
天の原	Ama no hara	As I gaze out, far
ふりさけ見れば	Furisake mireba	across the plains of heaven
春日なる	Kasuga naru	ah, at Kasuga,
三笠の山に	Mikasa no yama ni	from behind Mount Mikasa,
出でし月かも	Ideshi tsuki kamo	it’s the same moon that came out then!
