Prince Kachō Hiroatsu
Prince Kachō Hiroatsu (華頂宮博厚親王 Kachō no miya Hiroatsu Shinnō?, 18 January 1875 – 15 February 1883) of Japan, was the second head of the Kachō-no-miya collateral branch of the Japanese imperial family.
Prince Kachō Hiroatsu was the son of Prince Kachō Hirotsune, and succeeded his father as head of the Kachō-no-miya house on 25 May 1876. Due to his very young age, he was officially adopted by Emperor Meiji. Of weak constitution, Prince Hiroatsu died on 15 February 1883 at age eight.
To prevent the Kachō-no-miya line from becoming extinct, Emperor Meiji assigned Prince Fushimi Hiroyasu to succeed to the title in 1883.
