Ichiro Yamaguchi Is at It Again, Breaking All Conventions: From the Legendary COMME des GARÇONS T-shirt to Toyoharu Masushima’s Oil Paintings and a Coveted Sukajan—Here’s How to Dive Into His World Right Now

Ichiro Yamaguchi, the frontman of Sakanaction, is taking his collaborative frenzy to new heights—and it’s not just about music. Did you know that the legendary COMME des GARÇONS 1986 T-shirt, rumoured to have been worn on the down-low by Billie Eilish herself, is getting a surprise modern reissue? And apparently, Yamaguchi has already snagged the "CDG XL" size. Of course he has—the man’s eye is something else.

A 1986 COMME des GARÇONS piece reborn in Reiwa? The shirt "Yamaichi" chose

The buzz is all about that "COMME des GARÇONS 1986 t T-shirt". Faithfully recreating the original archive piece, this ultra-rare item is only being distributed as "new, authentic stock" to a handful of select shops. And who jumped on it first? Ichiro Yamaguchi. On his own radio show, he raved: "The whole vibe of the ’80s is sealed right into the packaging. You’re never seeing a T-shirt like this again." Known as the "Billie Eilish worn model" thanks to her love for it, the oversized "CDG XL" version sold out in a flash. Rumour has it that auction sites are already slapping on premium prices.

Meeting Toyoharu Masushima, the Italian-based maverick—oil paintings and teddy bear mayhem

But Yamaguchi’s rabbit hole doesn’t stop at fashion. The latest obsession? His collaboration with Toyoharu Masushima, a painter based in Italy. Masushima is an iconoclast known for his vivid blend of oil and acrylic painting, and his signature motif: the eerily cute green teddy bear. Yamaguchi apparently dropped by Masushima’s studio and hinted on social media that he now has an original painting by the artist hanging in his own home.

• The backstory on Masushima × Yamaguchi: For those in the know, Yamaguchi has been an avid collector of Masushima’s work for years. He once described a particular piece—a green teddy bear seemingly melting on canvas—as "the shape of my soul."
• What’s next for the original?: Rumours are swirling that apparel featuring this original painting might leak as merch for Sakanaction’s next tour. If true, it’s a guaranteed sellout.

The rich texture of oil painting meets the light-hearted toxicity of acrylic. Masushima’s world, dancing in that space between, syncs perfectly with the melodies Yamaguchi spins. It’s nothing short of "music you can see."

The fabled "Ainijyu Baby" collabo sukajan—details finally revealed

And here comes the big one: the piece fans have been waiting for. Yes, that item with the spellbindingly long tag—Ichiro Yamaguchi × Ainijyu Baby sukajan, Yamaichi, Sakanaction—is finally seeing the light of day. Born from a joint project with the legendary unit "Ainijyu Baby", this sukajan jacket is about to drop.

On the back? A massive green teddy bear freshly drawn by Toyoharu Masushima. On the front? A playful kanji logo that channels COMME des GARÇONS. Left sleeve: "1986" embroidery. Right sleeve: a "CDG XL" patch. This thing is absolutely packed with elements. It’s a piece that truly deserves to be called "the total art of Japanese subculture, filtered through Ichiro Yamaguchi."

Sales will likely be via lottery draw, at a certain spot in Shibuya and a few online stores. The price? Let’s not go there. But the moment you think "I want it," you’re already a resident of Yamaguchi’s rabbit hole. So—ready to dive in?
