In my planning for an upcoming trip to Japan, I stumbled upon a very clever service aimed at visitors. Any Wear, Anywhere is an inspired clothing rental plan that allows tourists to literally travel light.

The negative environmental effects of flying were weighing on Miho Moriya. “I love to travel but also felt guilty about using flights that produce CO2,” says the 40-year-old accountant based in Japan. So when her employer, Japanese trading house Sumitomo Mitsui Financial Group Inc., held its annual entrepreneurship competition in 2019, she pitched an idea that could make a tiny dent: a clothing-rental service for travelers. Instead of flyers hauling luggage—the weight adding to a plane’s carbon emissions—they could borrow clothes on the ground.

The idea became Any Wear, Anywhere, part of a venture between Sumitomo and Japan Airlines Co. Travelers arriving in Japan can now rent clothing for as little as $31 for up to two weeks, delivered to their hotel. The online service, more for the utilitarian-minded than the fashionista, rents sets—including perhaps three pairs of pants, three tops and a couple of jackets—all secondhand or sourced from overstock to keep with the eco-friendly vibe. It offers seven size options for adults and nine for children, with sweaters and jeans for winter and shorts and T-shirts for summer.

The service is currently available only in Japan, which happens to be enjoying a tourism boom. But traveling entirely suitcase-free is still just an aspiration: Shoes, underwear, PJs and toiletries aren’t yet part of the pitch. Moriya, who left her job in accounting to help operate Any Wear, Anywhere as its project leader, says going green feels good, but traveling without carrying luggage is even better. “My ultimate dream,” she says, “is making it possible to travel anywhere in the world hands-free.”
