The emperor's constitutional status became a focus of renewed public attention following news of Hirohito's serious illness in late 1988. Crown Prince Akihito became the first person to ascend the throne under the postwar system. One important symbolic issue was the choice of a new reign title under the "nengo" system which enumerates years beginning with the first year of a monarch's reign. Thus 1988 was Shōwa 63, the sixty-third year of the reign of Hirohito, the Shōwa Emperor. The accession of a new monarch is marked by the naming of a new era that consists of two auspicious Chinese characters. Shōwa (昭和), for example, means bright harmony. Critics deplored the secrecy with which such titles were chosen in the past, the decision being left to a government-appointed committee of experts, and advocated public discussion of the choice as a reflection of Japan's democratic values. Although the gengo system was accorded official status by a bill the Diet passed in June 1979, some favored the system's abandonment altogether in favor of the Western calendar. But on January 7, 1989, the day of Hirohito's death, the government announced that Heisei (平成, Achieving Peace) was the new era name. The first year of Heisei thus was 1989, and all official documents were so dated.
