Yanagisawa's eldest son, Mitsuo, joined Pearl in 1957 and formed a division to export Pearl products worldwide. To meet increasing worldwide demand for drum kits following the advent of rock and roll music, in 1961 Pearl built a 15,000 sq ft (1,400 m2) factory in Chiba, Japan to produce inexpensive drum kits, also known as "STENCIL KITS" that bore the brand names of more than thirty distributors such as Apollo, Coronet, Maxwin, CB-700, Stewart, Werco, Ideal, Crest, Revelle, Revere, Roxy, Lyra, Majestic, Silvertone, Toreador, WESTBURY and Whitehall.
