At Tomorrow’s Paris showroom, the box concept was made literal — clothes hung in and on a giant trunk, and piles of recycling boxes — to pique the imagination of store buyers. (Some interested stores have asked for the displays as well as the clothes.)

It is the first iteration of a new project organized by the Japan External Trade Organization (Jetro), Daisuke Gemma (an all-purpose connector and sounding board for Japanese brands) and the consulting arm of Tomorrow, which runs showrooms and offers business development services.

Mr. Kogi chose pieces from designers less known outside of Japan, including suiting by Auralee (he was wearing it himself, underneath a white leather Louis Vuitton harness as he showed visitors through the offerings); T-shirts by Midorikawa with stipple portraits of the minimalist avant-garde composer John Cage; and sweatshirts from Mr. Kogi’s own Poggy the Man collection embroidered with the letters L-O-V-E in a familiar-but-unplaceable bubbled logo.

“Do you know Devo?” he said. Ah, yes — there it is.
