From Yamanashi, a Major Gemstone Producing Region: D2C Jewelry Brand Otolo Officially Launches, Born from the Wholesale Business.

[Brand Overview]

In June 2026, Otolo was born as a D2C jewelry brand based in Yamanashi Prefecture, known as one of Japan's leading gemstone producing regions. With the concept of "Anytime, Anywhere with you.," the brand offers jewelry that serves as a companion for people living mobile lives in the modern era.

[Background of the Brand's Creation]

Through the designer's own life of continuous travel both domestically and internationally, the desire for "jewelry that can be worn anywhere, without worrying about the occasion or time," grew. To deliver jewelry that can be a daily companion rather than just for special occasions, Otolo was created.

Leveraging expertise in materials cultivated through direct overseas sourcing and collaboration with skilled artisans in Yamanashi, a gemstone-producing region, Otolo delivers jewelry that becomes a daily companion.

About Materials

Otolo's jewelry uses materials directly sourced by the designer from overseas, including Hong Kong. With expertise honed in the wholesale business, only materials that combine quality and beauty are carefully selected.

For diamonds, lab-grown diamonds are used. Lab-grown diamonds are genuine diamonds with the same carbon crystalline structure as natural diamonds, but they do not require mining, resulting in an extremely low environmental impact and are free from ethical risks such as conflict diamonds or poor labor conditions. Their brilliance and hardness are the same as natural diamonds, and the GIA (Gemological Institute of America) recognizes them as "real diamonds."

Beyond beauty, the integrity behind the product is one of the values that Otolo cherishes.

Designer's Message

I loved traveling even before starting in the wholesale business, and I especially loved preparing for trips. I loved the excitement of going somewhere and packing my favorite clothes and belongings until my bag was full. However, the more I traveled, the more I wanted to pack lighter. Yet, I still wanted to dress up properly when I was at my destination and didn't want to look sloppy even in travel clothes. It was then that I thought if there was jewelry that could be worn regardless of the occasion or time, it would make even travel outfits look more put-together while still wearing my favorites. That's why I decided to launch the brand.

Also, while traveling frequently, I often accidentally snagged my rings on my clothes. This first collection incorporates those experiences. We focused on stone settings that are less likely to catch on clothing and comfortable ring shapes, and after numerous discussions and trials with the factory, this collection was born.

As I worked on creating these products, so many people kindly cooperated. It was an opportunity to re-learn how many processes are involved in creating a single item and how many people are involved. I am truly grateful to everyone.

In this era of advancing AI, Otolo wants to cherish things created by human hands, the feelings, expressions, and creativity born from various human moments. We look forward to your continued support.
