Samidare no hi o furu mama ni Suzukagawa yaso se no nami zo koe masaru naru - Shika Wakashu(English Translation & Meaning)

五月雨の日をふるままに鈴鹿川
八十瀬の波ぞ声まさるなる

Roma-ji: Samidare no hi o furu mama ni Suzukagawa yaso se no nami zo koe masaru naru
English Translation: As the days go by
with the early-summer rains,
the Suzuka's waves
in all its eighty shallows
raise their voices ever higher.
Meaning: As the early-summer rains fall on and the days pass, the waves in the many shallows of the Suzuka River can be heard growing louder and louder.
Commentary: Book Two Summer Poems 65

The poem catches by ear how the Suzuka River, swollen by the ceaseless early-summer rains, grows louder each day as its waves rush through its many shallows.
Early-summer rain poems continue from here through poem 68. While this poem conveys the rising water by sound, "the voices rise," poem 67 conveys it visibly, "the water rises," treating the same theme through hearing and sight.

First line, "early-summer rains," names the long rains of the Fifth Month and opens the rain sequence.
Second line plays on furu, meaning both rain "falling" and days "passing."
Third line names the Suzuka River in Ise. Suzu means "bell," and furu ("shake"), "voice," and naru ("ring") are its associated words.
Fourth line, "eighty shallows," is a conventional way of speaking of the river's many shallows. The particle zo governs the attributive naru in the final line.
Fifth line uses naru for inference from hearing: the rising water is known by the sound of the waves.
