RECRRECRUIT | Sincere Inc.

Bringing a little smile to everyday life…

From Osaka to the world, we continue to deliver products that bring an effortless smile to anyone who holds them.

Recruitment Message

Sincere started in 2006 in a small office in Nipponbashi, Osaka. By maintaining an end-to-end approach—handling everything from planning and design to manufacturing and sales—we have brought products to countless customers through department stores, select shops nationwide, and OEM projects with major companies. The strong relationships of trust built with our long-standing partners remain one of our most cherished assets.

At the heart of what we do is a simple wish: to bring a little extra joy to someone’s daily life. Behind every hit product lies our ability to read market trends, an uncompromising dedication to craftsmanship, and a commitment to listening sincerely to our customers.

While we are still a growing team, this means every individual’s voice and idea directly shapes our next product or brand. Here, you will find an environment where you can truly feel that your work is bringing smiles to people’s faces.
