The poem
A most astonishing thing -- Seventy years have I lived;
(Hurrah for the flowers of Spring, For Spring is here again.)
Seventy years have I lived No ragged beggar-man, Seventy years have I lived, Seventy years man and boy, And never have I danced for joy.

very interesting poem. . .
"Imitated From The Japanese" as the title, I cannot make the connection with the context of the poem. Can you?
