April 29 marks the celebration of National Zipper Day in the United States, commemorating the day in 1913 when Gideon Sundback received a patent for the modern zipper. This invention revolutionized the fashion industry, providing a convenient and reliable method for fastening clothing and accessories. The zipper’s impact extends beyond fashion, finding applications in various industries, including luggage, outdoor gear, and even aerospace technology.

In Japan, April 29 is observed as Shōwa Day, honoring the birthday of Emperor Hirohito, known posthumously as Emperor Shōwa. His reign, from 1926 to 1989, encompassed significant events, including World War II and Japan’s subsequent recovery and economic growth. Shōwa Day serves as a time for reflection on the nation’s history and the challenges faced during the Shōwa era. It also marks the beginning of Japan’s Golden Week, a series of national holidays that are among the country’s busiest travel seasons.
