This paper describes the development of cast-in-place concrete piles at the dawn of Japanese foundation technology. The first cast-in-place concrete pile was <i>compressole pile</i> imported from France in 1907. The compressole pile was formed by dropping a hammer on the casted concrete in an excavated hole. Those piles installed at those days still exist in a number of historical buildings during more than 100 years. Following the compressole pile, <i>abbot pile</i> was introduced from the United States in 1910. The <i>abbot pile</i> is same manner to compressole pile, but using a casing tube to make a drilled hole.
