Mitsumasa Yonai
These various kinds of court uniforms continued to be used at court functions and ceremonies even into the Shōwa period, at events like the Imperial enthronement and the first visit of Emperor of Manchukuo Puyi to Japan. However, as the strain of war continued, opportunities for their use became rarer and rarer. When Mitsumasa Yonai became Prime Minister during the Second Sino-Japanese War, his morning dress could not be tailored in time for the appointment, and he wore a naval uniform in its place at his official investiture.
