Our thoughts
We at UMMY are the first D2C brand of freediving gear in Japan.
In a word, free diving is
Free diving refers to diving without breathing apparatus such as oxygen tanks, and only taking one breath. In other words, free diving includes not only competitive free diving, where participants compete to see who can dive the deepest, but also skin diving, snorkeling, spear fishing, and other free diving without breathing apparatus.
UMMY was born on Amami Oshima, the beloved island of its founder, an active free diver.
The founder himself has always found it inconvenient to purchase freediving gear in Japan. The number of stores and the variety of items are limited, it's hard to know what products are suitable for you, and the prices are high. If you look at overseas online stores, you will find many products that are not available in Japan, but there is the English language barrier, the explanations are hard to understand, you don't know if it will suit you, you are worried about whether it will arrive, and it is difficult to inquire... I'm sure all customers have had similar experiences.
Freediving in Japan is simply inconvenient and expensive.
And above all, Japan does not have a world-renowned brand that specializes in freediving gear. In other product categories, there are almost always world-renowned Japanese quality and Japanese brands. I think this is because freediving is still a minor marine activity compared to other countries.
So the founder decided to use his experience to find a solution and started UMMY.
Based on the above issues, we are a D2C brand that plans and designs high-quality products in Japan and delivers them directly, which allows us to achieve high cost performance, free shipping on all products in Japan (excluding overseas), and reliable customer service.
The name UMMY comes from the word "sea (UMI)," which is essential for our survival.
The blonde UMMY logo features images of waves, a fish tail, diving fins, and the word UMMY.
Through UMMY, we aim to create an opportunity for everyone to start free diving.
And I want to spread the wonderfulness of freediving, where you can swim freely without being bound by anything.
Together with our customers, we will promote UMMY and grow it into a world-renowned Japanese freediving brand.

After graduating from university, he worked at Rakuten, Inc. and Amazon Japan, LLC, where he was involved in consulting for EC businesses. Using his experience, he moved to Accenture, one of the world's largest consulting firms, where he was involved in business strategy planning and EC business launch support for major retail companies.
Having never lived a life that had nothing to do with the sea, he was enchanted by the ocean on his first visit to Amami Oshima, and his life changed dramatically.
He started free diving in 2021 and has been touring the oceans of Japan, building friendships with free divers all over the country. Despite having no prior experience of diving in the ocean, he was able to dive to a depth of about -50m in just six months.
In spring 2022, he will launch UMMY, Japan's first D2C freediving gear brand, leveraging his experience in e-commerce and freediving.
