Koyuki gave birth to their first son in January 2012 and their daughter in January the following year. During the birth of their second child, Koyuki went to Seoul, South Korea for the delivery as she had been impressed with the post-birth services there. However, as announced by her agency, she will stay in Japan for the delivery this time. Koyuki is expected to return to work for the promotion of her movie "Sugihara Chiune" in autumn this year.
