[All] [Bunshun] Is Kentaro Sakaguchi's hair and makeup girlfriend Ayano Iwane? A thorough explanation of the truth from cohabitation to breakup

Who was the girlfriend with whom Kentaro Sakaguchi lived for over four years? We'll take a closer look at why the "hair and makeup girl three years older than him" reported by Bunshun is rumored to be Ayano Iwane, their cohabitation life before marriage, the background to their breakup, his love triangle with Mei Nagano, and his past relationship with Mitsuki Takahata.

1. Bunshun report on Sakaguchi Kentaro: Who is his girlfriend?

On September 10, 2025, Shukan Bunshun reported that Kentaro Sakaguchi was living with a hair and makeup artist three years his senior. According to the article, the two had been living together in a luxury apartment in Tokyo for over four years and had even met each other's parents. Sakaguchi is popular as one of the most handsome men in the entertainment industry, but surprisingly, it turns out that he is not in a flashy relationship, but rather in a stable, long-term one.

2. Characteristics and profile of "Ms. A"

The characteristics of "Ms. A" that are commonly mentioned in the Bunshun article and multiple media outlets are as follows:

As such, it's easy to see why Sakaguchi has lived with her for so long, as she is not only appreciated for her appearance but also for her personality and work performance.

3. The theory that Aya Iwane is the identity of the person and its basis

On social media and message boards, there was widespread speculation that Ms. A might be the popular hair and makeup artist Iwane Ayano. This is because the career profile reported by Bunshun matches Iwane's track record. For example, Iwane was in charge of hair and makeup for Tabe Mikako in the TBS drama "My Family," and the same career profile was also mentioned in an interview with a graduate of Kansai Beauty College. Many people believe that this circumstantial evidence makes it "almost certain," but it remains merely speculation.

4. The reality of dating and living together for over four years

Their relationship lasted for at least four years, and those around them even said that it was only a matter of time before they got married. They had even met each other's parents, and he was apparently making his presence known as a partner who supported Sakaguchi's private life. However, in 2025, rumors of a breakup began to surface. The reason for this is unclear, but since Sakaguchi herself had said that she wanted to "spread her wings and take to the world," it is speculated that differences in their career paths may have been a factor.

5. Reports of a love triangle with Mei Nagano

What further fueled the buzz was his relationship with Nagano Mei. Nagano's agency acknowledged that "it is true that they had dated in the past," but explained that they were unaware that another woman (A-ko) was involved at the same time. This raised suspicions that "it was a love triangle." This sparked a major debate on social media, and had a significant impact on Sakaguchi's image.

6. Past serious relationship with Mitsuki Takahata

One of Sakaguchi's most famous romantic experiences is his relationship with Mitsuki Takahata. The couple began dating after co-starring in the 2016 film "Toto Neechan" and continued their serious relationship for four years. At the time, it was said that they were close to getting married, but they eventually broke up. This is a typical example of Sakaguchi's devoted, long-term relationship personality.

7. Kentaro Sakaguchi's romantic tendencies and views on marriage

In his past relationships, Sakaguchi has always chosen long-term, stable relationships over short-term flings. He seems to prioritize "comfort" and "consideration" over appearances, and tends to seek a sense of security from his partner. Regarding marriage, he has said that he "wants to cherish the timing," revealing his attitude of valuing his own pace and not being influenced by the expectations of those around him.

8. Changes in fan and public reactions

Immediately after the news broke, the fact that they had been together for over four years and that he was devoted to an older woman drew positive reactions, but once the news of a love triangle broke, criticism began to emerge. Even his past collaboration with BLACKPINK's LISA was dug up, and the incident became an international outrage on social media.

9. Impact on future activities

Sakaguchi is set to star in the upcoming film "Sunflowers on the Board," due for release in October, and is gaining popularity in Korea. Although the dating scandal has caused some damage, he is regarded in the industry as a "sincere and affable actor," so it is not expected to have a major impact in the long term.

10. Summary: What will happen with her?

There is a strong rumor that Sakaguchi Kentaro's live-in girlfriend is Iwane Aya, and they have been in a serious relationship for over four years and were even said to be on the verge of marriage. However, with reports of their breakup and his relationship with Nagano Mei, the truth remains unclear. Attention will continue to be focused on his future love life, marriage, and his activities as an actor.
