Answer:
He uses imagery to present the subject.
Step-by-step explanation:
The poet creates an image of every representation/object described in the poem in the imagination of the reader. The poet ensures that the senses of the readers are carried along, most especially the senses of touch and feeling.
He said, "It is because the sea is blue, Because Fuji is blue, because the bent blue Men have white faces, like the snow On Fuji, like the crest of the wave in the sky the color of their Boats." Every object described here appeals to the senses of the readers. He did not do without giving the details of every thing mentioned. This is typical of presenting a subject using imagery.
