The major breakthrough for Zard came with the sixth single in 1993, "Makenaide", which became No. 1 in the Oricon charts and went on to sell over 1.8 million copies. She went on to release two more songs that reached No. 1, "Yureru Omoi" and "Kitto Wasurenai" in the same year. An album titled "Yureru Omoi" featuring both "Makenaide" and "Yureru Omoi" sold two million copies, the first million milestone for Zard in album sales. In fact, Being was so successful in the early 1990s that it was called Being Boom. No one sold more CDs than Zard in this year.
