TOKYO—Japan’s Princess Mako will marry a commoner in a subdued ritual on Tuesday after a four-year engagement plagued by scandal and media speculation, which has left the 29-year-old with post-traumatic stress disorder (PTSD).
She will become an ordinary citizen after marrying Kei Komuro, a 30-year-old Japanese law graduate who lives in New York, in line with laws mandating female royal family members abandon royal status.
