🎙️ The "last piece" Japan has been waiting for since spring just dropped — and it's a name even casual American music fans would recognize. Number_i, the three-man group made up of former King & Prince members Sho Hirano, Yuta Jinguji and Yuta Kishi, has signed with Atlantic Records in the United States. They're now labelmates with Ed Sheeran, Bruno Mars, Coldplay and Rosé — and yes, that's the same Bruno Mars they already share an agency with at WME.

This is the second half of a global setup that started in February. And it's the move many of us in Japan have been watching for since their TOBE boss Tak Takizawa publicly hinted at a "final piece" landing right around the Sapporo dome shows.

So what actually happened, and when

The announcement came on May 17 in Sapporo, just before the to HEROes ~TOBE 3rd Super Live~ concert at Hokkaido's Daiwa House Premist Dome — the massive TOBE label showcase featuring 34 artists. The three members confirmed the deal in front of Japanese reporters, then walked into the venue to perform.

The official press releases dropped the next morning, May 18, lighting up Japanese music media from Billboard Japan to Rolling Stone Japan to Oricon.

According to Japanese sport tabloid Sponichi, Number_i's group statement read in part:

"We've signed with the American label Atlantic Records. We can't wait to see how far our range can expand with Atlantic. We'll work hard to deliver our music to more people."

Members have already been to Atlantic's Los Angeles office this spring, and songwriting sessions with American staff are already underway. Lyrics could be in English, Japanese, or a mix — they haven't locked that in yet.

What is Atlantic Records, exactly?

For non-music-industry readers: this isn't a boutique indie label or a regional partner. Atlantic is one of the founding pillars of modern American music.

Founded in 1947 by Ahmet Ertegun and Herb Abramson, Atlantic helped define R&B and soul through the mid-20th century with artists like Aretha Franklin, Ray Charles and Otis Redding. After becoming part of what is now Warner Music Group in the late 1960s, it expanded into rock with Led Zeppelin, Crosby, Stills, Nash & Young, and beyond.

Today's roster is just as heavy: Ed Sheeran, Bruno Mars, Coldplay, Charlie Puth, Cardi B, Twenty One Pilots, Burna Boy. On the K-pop front, BLACKPINK's Rosé recently released her solo work through Atlantic. It is, in short, a frontline major-label imprint within one of the "Big Three" recorded music companies on earth.

For a Japanese male act to be slotted into this lineup is not a footnote. It's a first in any meaningful sense.

"But wait — didn't they already sign with WME in February?"

This is the question Japanese fans have been politely asking online for the past 12 hours, so let's untangle it. The two deals are completely different things, and Number_i now has both.

Deal Type Signed What it does
WME (William Morris Endeavor) Talent agency Feb 2026 Books tours, brand deals, TV, film, global representation
Atlantic Records Record label (Warner Music Group) May 2026 Releases music, A&R, marketing, US/global distribution

Put crudely: WME books the rooms. Atlantic makes and releases the records. A modern global pop career typically needs both. Bruno Mars, just to pick one obvious example, is signed to WME and to Atlantic — which means Number_i and Bruno Mars are now both labelmates and agency-mates. That's not a publicist's flourish; it's actually how the business works.

TOBE remains Number_i's home agency and management — that hasn't changed. What's happened over the past three months is that the trio has bolted on US-side infrastructure on top of TOBE, in two distinct layers.

If you've been reading kantenna coverage of the WME signing back in February or Takizawa's "last piece" tease in April — this is the piece. The setup is complete.

"Their style first" — not chasing charts

One thing worth flagging early: this is not a group going to America to chase Billboard Hot 100 placements at any cost.

Hirano told reporters that he wants to "stick to our own style" rather than aim purely at chart positions. Jinguji emphasized that Japan remains the base — "we can take on these challenges because Japanese fans have supported us." Kishi said he's pouring everything into the immediate songwriting work, with collaborations being a "someday" thing.

There's no English-only pivot, no rebranding, no cosplay attempt at being a K-pop group. They've been making bilingual, hip-hop-leaning J-pop with self-direction since their 2024 debut "GOAT," and that posture clearly isn't changing under Atlantic.

Asked about the Grammys, Jinguji laughed it off: "It's so big I can't really picture it, but if we keep making music we think is good, maybe one day."

Why this is a historic move for Japanese male artists

To overseas readers it might look like a fairly normal label signing. Inside Japan it isn't. To put it bluntly:

Japan is the world's second-largest recorded music market. For most of the past 40 years, that scale was sufficient — Japanese artists could earn a full career staying domestic, and major labels and management firms here optimized for that. The old Johnny & Associates (now STARTO Entertainment), which produced the country's most successful boy bands for half a century, didn't even allow most of its catalog onto global streaming services until the late 2010s. The reflex against international distribution was that deeply baked in.

Hirano, Jinguji and Kishi came out of that exact system as King & Prince members, left for the newly founded TOBE in 2023, and have spent the past two and a half years building something that didn't quite exist before: a Japanese male group whose business model is global-shaped from the start — but in Japanese, on their terms, signed to American infrastructure layered on top of a Japanese agency.

A few comparison points to anchor it:

  • K-pop big four (HYBE, SM, YG, JYP) have had US major-label deals as standard for years — BTS via Columbia/Sony, BLACKPINK via Interscope, NewJeans via Geffen-side partnerships, etc.
  • Japanese acts on US major labels have been almost entirely women or alt/rock acts — Hikaru Utada with Island Def Jam years ago, Babymetal with their own setup via 5B/Cooking Vinyl, XG via Geffen.
  • Japanese male groups signing directly to a US major frontline label as their primary US partner — there really isn't a precedent at this scale.

That's the line being crossed.

The 88rising bridge, and why Atlantic specifically

Number_i's path to Atlantic didn't start in May 2026. It started, roughly, two years ago at Coachella.

In April 2024, the group performed at Coachella under 88rising's "Futures" slot — a showcase for emerging Asian artists. By June 2025 they were back in California for HEAD IN THE CLOUDS LA as a featured act (not the development slot). Along the way they remixed Jackson Wang's "GBAD," landed Billboard Japan No. 1s, and quietly built a US footprint without forcing the issue.

Sponichi reports that Atlantic's pitch to the group hinged on the freshness of the music — "the songs felt fresh to them" was apparently the phrasing. About a year of conversations with Takizawa shaped the deal. So this isn't a label slapping a Japanese boy band on its roster for K-pop adjacent business reasons; according to the parties, Atlantic actively wanted what Number_i sounds like.

What we don't know yet

Plenty:

  • Release date of the first Atlantic single or EP: not announced
  • Language strategy: still being decided (English / Japanese / mixed)
  • First US tour: no dates, though Jinguji floated "world tour someday" as the dream
  • Whether WME's touring arm will move on US dates this year: open
  • Any collaboration with current labelmates (Bruno, Ed, Coldplay, Rosé etc.): Kishi said "someday it would be fun" — i.e., nothing concrete

What we do know is that Japanese fan-meeting dates in Osaka (July) and Tokyo (August) are already on the calendar, so the trio isn't abandoning the home market while the US machinery spins up.

So — does Number_i actually mean anything where you are?

That's the honest question. In Japan, Number_i is a top-tier act and this announcement is a national-headline story. Internationally, awareness skews heavily toward Asian-diaspora audiences in the US, Coachella attendees, 88rising followers, and the existing K-pop/J-pop crossover crowd. Among general Western pop listeners, they're still mostly unknown.

Atlantic's job, presumably, is to change that.

If you're reading this from outside Japan: Have you heard of Number_i? Did the Coachella or HEAD IN THE CLOUDS sets cross your radar? And honestly — what would it take for a Japanese male group to land with you the way K-pop already has? We'd love to hear what would actually move the needle in your market.
