Japanese entertainment just added another big life update. Mizukami Koshi (26) has officially announced his marriage to a non-celebrity woman, while also confirming that the couple are expecting their first child.
The announcement was made on 28 January through the official website of his agency, 合同会社HAKU, putting an end to weeks of quiet speculation and confirming that 2026 is already shaping up to be a year full of celebrity weddings in Japan.
In the agency’s statement, it was clearly shared that Mizukami Koshi has registered his marriage and that his wife is currently pregnant with their first child.
The agency also stressed that any official updates would only come directly from them, asking media outlets to avoid speculation or intrusive coverage.
His wife is described as a private individual, and the agency firmly requested respect for her privacy, including refraining from interviews or unnecessary attention.
Back in early November 2025, Mizukami Koshi was spotted enjoying a casual shopping date with his girlfriend. At the time, he personally confirmed that they were dating, while his agency clarified that the couple were not living together. It was also revealed that she is older than him and not part of the entertainment industry.
Fast forward a few months, and the relationship has now taken a major step forward with marriage and a growing family.

Mizukami’s announcement comes amid a noticeable trend of leading Japanese actors tying the knot in 2026. Earlier this year, Hongo Kanata (35) and Kamiki Ryunosuke (32) both announced their marriages to non-celebrities.
Just weeks ago, Kamio Fuju (27) surprised fans by revealing his marriage to singer and actress Hirate Yurina, formerly of Keyakizaka46.
That unexpected pairing sparked massive discussion online and further highlighted how active this year has been for celebrity marriage news.
Online reactions to Mizukami Koshi’s news have been largely positive. Many fans expressed surprise at how quickly the announcement arrived but quickly shifted to congratulatory messages, praising his sincerity and mature decision-making at a young age.
Some netizens also pointed out how refreshing it feels to see rising actors openly prioritising family life while continuing their careers. Others were simply amused by how 2026 seems to be turning into a “marriage rush” year for Japan’s leading men.
There were also fans revisiting his past interviews and performances, noting how this new chapter adds depth to his public image and personal growth.
Despite the personal milestone, the agency reassured fans that Mizukami Koshi will continue his acting career with full commitment. With marriage and fatherhood ahead, many are now curious to see how this new life phase will influence his future roles and projects.
