Sachiko, Princess Hisa (久宮祐子内親王, Hisa-no-miya Sachiko Naishinnō, 10 September 1927 – 8 March 1928) was the second daughter and child of Emperor Shōwa and his wife, Empress Kōjun.


On 10 September 1927, the Emperor and Empress's second child was born, a daughter who weighed 3.3 kilograms (7 lb 4 oz) and had a length of 51 centimetres (1 ft 8 in).

The princess was named Sachiko on 16 September, a name chosen by the Emperor himself. The princess grew steadily and was breastfed.


By February 27, the princess developed an eczema and a high fever and was diagnosed with catarrh. On 1 March, the doctor announced that no one should worry and, on 3 March, it was announced she was expected to recover. However, on 4 March, the princess developed a very high fever, 39 °C and, by 9 pm, she was suspected of sepsis. Birthday events for the Empress were canceled on 6 March.

On 8 March, her medical condition continued to deteriorate and the infant princess died at 3:38 am. The Emperor ordered the army to stop their actions for the day and decreed a day of national mourning. On 13 March, the princess was buried in a simple ceremony in the Toshimagaoka cemetery. The Empress was devastated; she held a doll of about the same size as Sachiko for days and would not have another child for one more year.
