Shaku Yumiko announced through her blog that she had given birth to her first son on 12 June which also happens to be her birthday. In her statement, she revealed that her son weighed 2,890g at birth and it felt like it was a double birthday celebration for her as she was also celebrating her 38th birthday that day. She was having a checkup the previous day when the doctor suggested that she should be warded immediately that evening as she was showing signs of labour. Despite this being her first time, the delivery process was very smooth and didn't take a long time.
Shaku got married to her husband who is of the same age to her in October last year.
