aiso^ ya nobe no kusa sae waka-zakari
even the meadow grasses
hit their peak young
by Issa, 1814
Aiso^ or aiso denotes; amiability, affability. These English equivalents sound too cold for this context; I hope that "lovely" expresses Issa's warm and tender feeling toward the young grasses.
1814, Age 52
Fourth Month, Issa marries with Kiku.
