Here is a poem written in Chinese by Ikkyū, from the Kyōun shū (狂雲集, "Crazy Cloud collection"). The title is 乱中大嘗会, "Wartime combined-harvest-and-emperor-confirming-ceremony". (Daijōe: hard to translate.)

当今聖代百王蹤
玉体金剛平穏容
風吹不動五雲月
雪圧難摧万歳松

Here is how YANAGIDA Seizan trots it in his translation of the KS, published by Kōdansha in their "Classics of Zen" (禅の古典) series:

当今、聖代、百王の蹤、
玉体は金剛のごとく、平穏の容。
風吹けども動ぜず、五雲の月、
雪圧せども摧き難し、万歳の松。

Romanized:

Tōkon, seidai, hyaku-ō no ato,
Gyokudai wa shingō no gotoku heion no kao.
Kaze fukedomo dōzezu, go-un no tsuki,
Yuki osedomo kudakigatashi, banzai no matsu.

Translated as prose:

The present [emperor], his sacred reign, heir to a hundred kings,
His presence is like diamond, his visage calm.
Though the wind blows he is not disturbed: a moon among five-[colored] clouds,
Though the snow presses he does not break: a ten-thousand-year-old pine.

The emperor here was Tsuchimikado II, who was enthroned just before what turned out to be the Ōnin War. Given the likelihood of being killed more or less at random in those days, it isn't surprising that Ikkyū should have come out in favor of peace, stability, the good old days, and the hundred-odd emperors who presided over them. (And let's not forget that one of those emperors was Ikkyū's own father.)

Anyway, what I like about Yanagida's edition is that he also provides a translation into more poetic Japanese, using 7- and 5-syllable lines (give or take some hypermetricity):

今上天皇、百代うけた、
仁王のからだ、温和なひとみ。
風にも動かぬ、月のかげ、
雪にも折れぬ、千代の松。

Romanized:

Kinjō tennō, hyakudai uketa,
Ni-ō no karada, onwa na hitomi.
Kaze ni mo ugokanu, tsuki no kage,
Yuki ni mo orenu, chiyo no matsu.

In pentameter:

Our emperor, his line one hundred strong:
A Hercules in form, though mild of eye;
A steadfast moon, unmoved by any wind;
An ancient pine, unbending in the snow.

It isn't often you can make legitimate use of Hercules in a translation from Japanese, but I claim that right, because Herakles was the original inspiration for the game of iconographic telephone played down the Silk Road that ended in the "Deva Kings" (仁王) mentioned in the original. Go Indo-Europe!
