| Sakaguchi Kentaro’s Relationship Revealed Amid Triangle Love Scandal Rumours |
Shukan Bunshun has dropped a new scoop on Sakaguchi Kentaro (34), revealing that the actor is in a long-term relationship with a hairstylist three years his senior.
The pair are said to be living together at his apartment in Tokyo, with the romance quietly going strong for four years.
But the story doesn’t end there.
The weekly magazine is teasing a follow-up set to run tomorrow, hinting at the involvement of another actress that could turn this into a triangle storyline.

Kentaro Sakaguchi first stepped into the spotlight at 19 as a model for Men’s Non-no before making his acting debut in 2014.
His career truly skyrocketed in 2021 thanks to NHK’s morning drama Okaeri Mone, where his role as the blunt yet warm-hearted doctor Sugimoto Kotaro charmed audiences.
Viewers affectionately dubbed him “Our Suganami” on social media, cementing his breakout.

In recent years, Sakaguchi’s popularity has spread beyond Japan. Particularly in South Korea, he’s been hailed as one of the most beloved foreign stars.
He fronted Uniqlo campaigns in 2024 and 2025, landed roles in Korean dramas, and even picked up a Best Actor trophy at the Global OTT Awards in Busan.
Still, rapid fame hasn’t come without bumps.
Just last month, a behind-the-scenes snap shared by BLACKPINK’s Lisa—showing her playfully biting his arm—sparked online debate in South Korea.
While she had long called herself his fan, the post’s intimate vibe caused a stir before the storm eventually cooled.

Now Bunshun claims Sakaguchi Kentaro has been happily partnered with “A”, a Tokyo hairstylist, for several years.
The magazine says the two share a cosy life in the city, supported by friends’ accounts and so-called “scoop photos.”
Details of how they first met, their closeness, and their agency’s stance are included in Bunshun’s digital edition.
The bigger question for fans is the cliff-hanger: tomorrow’s release reportedly brings in the name of an actress tied to Sakaguchi Kentaro, fuelling speculation of a triangle dynamic. Whether that twist is a passing rumour or something deeper remains to be seen—but one thing’s for sure, his private life is about to become the talk of both Japanese and Korean fandoms.
