1. Matsumura Sayuri announces marriage and pregnancy at the same time

On December 3, 2025, Matsumura Sayuri simultaneously announced her marriage and pregnancy on her Instagram. In a message posted alongside a photo of her in a white dress holding her beloved dog, she not only announced her marriage but also stated, "We have been blessed with a new life," prompting congratulations not only from fans but from the entertainment industry as a whole. Matsumura herself stated that she was "currently in the stable period," and her agency quickly officially acknowledged the announcement.

Since her debut as a member of Nogizaka46's first generation in 2012, Matsumura has garnered popularity for her natural cheerfulness and unique character, and has continued to appear in variety shows, dramas, and movies even after graduating from the group. She was so popular that her graduation concert was held over two days at Yokohama Arena, and the news of her simultaneous marriage and pregnancy instantly attracted a great deal of attention.

The reason behind her simultaneous announcement of her pregnancy and marriage is thought to be her intention to clarify her schedule leading up to the birth and adjust her future entertainment activities. Matsumura herself has stated that she "wants to continue working in a way that is true to myself," suggesting that she intends to balance her new role as a mother with her career as a talent.

2. Profile of her spouse and reports

Matsumura Sayuri's husband is reportedly an older man who works at a company in Tokyo (Marunouchi). As he is a private citizen, his name has not been made public, but according to testimony from those around him, he has a "rugby player's build" and is known for being cheerful and friendly. Some media outlets have also described him as having an "atmosphere similar to Sandwichman's Tomizawa Takeshi," suggesting he is a man with both a sturdy build and a gentle demeanor.

Their relationship became widely known after a report in Smart FLASH in May 2024. At the time, Matsumura expressed a cautious stance on marriage, saying in an interview that "we're not at that stage yet," but behind the scenes, their relationship continued to be warm and stable, which is thought to have led to their current marriage. Perhaps he was close to the ideal "prince slayer" and "romantic man" that Matsumura had described on dating shows.

3. The truth behind the "Dentsu man theory" and how it came about

Rumors suddenly began to spread online about her husband, saying that he might be a top salesman at Dentsu. This rumor spread because of the information that he worked in Marunouchi, and also because it was easy to imagine that he worked in an industry that gave him many opportunities to come into contact with celebrities. It was also generally believed that he was likely a high-income, sociable man, and keywords such as "Marunouchi," "athletic," and "connections with the entertainment industry" were linked together on social media.

However, the only information officially confirmed at this point is that he is an "older company employee working for a company in Tokyo," and there is no evidence that he works for Dentsu. Large companies with offices in Marunouchi, such as Dentsu, Hakuhodo, Nomura Securities, and Mitsubishi Estate, are being mentioned as possible candidates, but this is merely speculation and cannot be said to be highly reliable information.

It has not been reported which company she actually works for, and considering that Matsumura's husband is an ordinary citizen, further speculation about his occupation should be avoided.

For reference, the following is a list of companies with many employees working in Marunouchi that has been circulating online.

Guessed company name	Easy connection to the entertainment industry	Athletic tendencies	Annual income level	remarks
Dentsu	Very high	expensive	expensive	His frequent contact with celebrities is the source of rumors
Hakuhodo DY	expensive	Medium to high	expensive	Opportunities for contact as an advertising agency
Nomura Securities	Medium	Very high	expensive	Athletic culture is symbolic
Mitsubishi Estate	Medium	Medium	expensive	A prestigious company representing Marunouchi
Mitsui Fudosan	Medium	Medium	expensive	Mainly Nihonbashi, but also strong in Marunouchi

The above is merely a collection of rumors and has nothing to do with the person's occupation.

4. The inside story of a two-year relationship and how it has changed

The two are said to have been dating for about two years, and have been nurturing their relationship for a long time since the initial reports. When their relationship was first revealed in 2024, Matsumura said she wanted to "focus on her work," and it seems she had no intention of getting married right away. However, as their relationship progressed, her husband's sincerity and kindness were recognized by those around him, and marriage seemed to be a natural progression.

Furthermore, Matsumura has spoken about her "ideal image of marriage" in past interviews, and it is highly likely that her current partner is the closest to that ideal. The fact that the man has the build of a rugby player and is cheerful and kind perfectly fits the criteria that Matsumura has been looking for as she gets older - a "partner who gives me peace of mind."

Their relationship was not flashy, and it appears that she had maintained a quiet and peaceful relationship with a man who was deeply understanding of her work. Taking into account the timing of her pregnancy and the stable period, it can be said that announcing their marriage was a natural decision.

5. Nogizaka46's "marriage rush" and Matsumura Sayuri's position

Matsumura's marriage marks the ninth marriage announcement by a former Nogizaka46 member. Starting with the marriage of Nishino Nanase and Yamada Yuki in 2023, 2024-2025 saw a string of marriages, with alumni experiencing a series of turning points in their lives, including Nojo Ami's engagement announcement. Meanwhile, one member who has given birth is Eto Misa, who serves as a role model for female talents who continue to work while raising a family.

Matsumura's marriage and pregnancy are seen as a symbolic move in this trend. She has been a central figure in Nogizaka's first generation since her debut, and has continued to be active in a wide range of genres since graduating. This announcement marks a milestone for fans who have supported her for many years, and is also being viewed positively as the beginning of a new Sayuringo.
