| Takahashi Kaito and Arimura Kasumi Reportedly Heading for Marriage After 5-Year Romance |
Looks like wedding bells might be on the horizon for one of J-ent’s most lowkey (but long-running) couples — Arimura Kasumi and King & Prince’s Takahashi Kaito. Yep, according to a fresh update from Shukan Bunshun, the pair’s relationship is not only still alive, but more solid than ever, and fans are now buzzing about the possibility of marriage.
Let’s rewind a bit. These two first crossed paths on the 2020 drama Nee-chan no Koibito, where Kasumi played the big-sister breadwinner and Kaito was cast as one of her younger brothers. On-screen family, off-screen spark? Seems like it.
Reports started surfacing in late 2023 that they’d been dating quietly for about three years by then — a huge deal considering Kaito’s idol status and Kasumi being six years his senior.
But then in mid-2024, breakup rumours suddenly started doing the rounds. Some speculated their busy careers pulled them apart, or that pressure from fans and management made things complicated. However, that narrative's just been flipped. Bunshun now reports the couple never split, and their connection is still going steady after almost five years.
And the kicker? Back in 2023, Kasumi Arimura was seen being picked up from work by none other than Kaito Takahashi himself. Not part of the cast, not staff, just... her man showing up. That kind of public move doesn’t scream casual fling.

Fans on X (formerly Twitter) are already speculating:
“Kasumi’s already 32 – if they’re serious, maybe marriage is next?”
“She probably wants to settle down soon, but Kaito’s still in his 20s and a big idol… tough one.”
“Wonder if their agencies would even allow it…”
That last point is key. With King & Prince being a flagship act under STARTO Entertainment and Arashi wrapping up for good in 2026, Kaito’s status is vital. A sudden marriage could risk fan backlash or shake up the group’s momentum. That said, Arimura Kasumi’s not exactly someone the public would reject — she's got a clean image, a strong acting resume, and has always handled rumours gracefully.
Remember that whole sumo wrestler thing in 2021? She was linked to Meisei at the time, but her agency came out swinging, calling it totally false and even threatening legal action. In contrast, when the news broke about her and Kaito, her team responded more gently, just saying they were “close.” Big difference, and fans noticed.
Insiders say there was a rough patch after their relationship first went public, possibly due to pressure or not being able to meet up as freely. But the love? Still there. Whether or not they actually head down the aisle soon, it’s clear these two aren’t just a fling.
Five years together in the unpredictable world of J-celebs is no joke. Even if a marriage isn’t announced tomorrow, this couple’s got staying power — and fans are watching closely for the next chapter.
