ヨイトマケの歌

Kenneth James Bryson says:

These may actually be young women and ladies,
working on a soil compaction rig. They pull the ropes,
which raise a large vertical log; they let go, and the log
comes down to tamp the earth.
They would chant "yo-i to make" (heave ho, roll it up")
each time, so they were called "yoitomake" women.
It was a lowly and arduous job. A popular singer
in the 1960's recorded a song called "The Yoitomake Song",
which was suppressed by the government because
the term was considered by that time to be derogatory
to working women.
