Our Story
From Tokyo to Valencia
Curating Japan's finest pre-owned luxury for Europe
The Japan Advantage
Why Japan?
Japanese collectors treat luxury bags like heirlooms.
While bags in Europe and America get used daily, tossed in closets, and resold worn — Japanese owners store their Chanel in dust bags, their Hermès in climate-controlled wardrobes, their Louis Vuitton in original packaging. Many pieces are carried only a handful of times.
The result? We find 20-year-old bags that look like they left the boutique yesterday.
Japan's pre-owned luxury market is also the most rigorous in the world. Authentication standards are stricter. Condition grading is more precise. Fakes don't survive.
Mai's relationships with Japan's most trusted vintage dealers — built over years — give Treasures of Maimi access to pieces you simply won't find anywhere else in Spain.
SOURCING IN TOKYO
The Founder
Meet Mai
Mai grew up surrounded by craftsmanship. In Japan, quality isn't just appreciated — it's expected. A bag isn't disposable fashion. It's an investment. A piece of art. Something you pass down.
After moving to Valencia, Mai noticed something: the pre-owned luxury market in Spain was full of worn-out pieces and uncertain authenticity. Meanwhile, her friends back in Tokyo were selling pristine Chanel bags for fair prices to buyers who understood their value.
The gap was obvious. The opportunity was clear.
In 2024, Mai founded Treasures of Maimi to bridge that gap — bringing Japan's exceptional pre-owned luxury to Spain and Europe. Every few months, she returns to Tokyo and Osaka, visiting trusted dealers she's known for years, hand-selecting only the pieces that meet her standards.
"I reject more bags than I buy. If I wouldn't carry it myself, I won't sell it to you. Japanese culture respects craftsmanship — a Hermès bag isn't just fashion, it's heritage. That's why bags there stay pristine for decades."
— Mai, Founder
