[Machine Translation] Ryoichi Hattori, a composer who became an exclusive writer for Nippon Columbia in 1936, was one of the three most popular composers of the Showa period (along with Masao Koga and Yuji Koseki), and left approximately 3,000 works during his lifetime, including songs, school songs, company songs, and advertising songs. Hattori's melodies are characterized by a rhythmical style that skillfully incorporates Western music such as jazz, blues, and boogie-woogie, but there are many fine songs that have been overshadowed by such hits. There are many works that incorporate Western rhythms, which are Ryoichi Hattori's specialty, but have not stood out.
