Mizuki Arisa announced through her agency on 22 March that she has married her boyfriend of one and a half years i.e. Aoyama Koji, the president of a construction-related company, a day earlier. The statement which was handwritten by Mizuki, was sent by fax to the media in the evening of 22 March where it was mentioned that the couple submitted the marriage application and are already living together. However, there are no plans for a wedding yet and Mizuki is currently not pregnant and will continue working as an actress. Aoyama was previously married to another celebrity Uehara Sakura but they split up in April 2013. Mizuki and Aoyama had been friends for some time but only started dating in the autumn of 2013. They were caught by the paparazzi for having gone on trips together to Tahiti in April last year and France in July of the same year.
Mizuki made her debut as a singer when she was 14 in 1991 and currently holds the record for having taken on leading roles in dramas for 24 consecutive years.
