Japanese Engineering Giant O2 Box Brings 26-Year Legacy to $6+ Billion U.S. Wellness Market with Breakthrough Anti-Claustrophobic Design of Hyperbaric Spaces

Sanso2, the leading mild hyperbaric oxygen therapy technology company, powered by wellness-technology leader O2 Box, today announced the opening of its U.S. flagship showroom in New York City. Founded by Takafumi Kato, Asia's leading hyperbaric technology manufacturer, Sanso2 delivers accessible oxygen recovery spaces that revolutionize the traditional hyperbaric oxygen therapy (HBOT) experience.

The company's innovative approach replaces conventional "coffin-like" chambers with spacious, comfortable rooms where users remain clothed and can work, socialize, or simply relax during sessions. This breakthrough design addresses the hyperbaric oxygen therapy market's biggest consumer barriers: claustrophobia and anxiety.

Market research shows that potential HBOT users are significantly deterred by traditional chamber experiences, with claustrophobia and anxiety identified as major barriers to treatment. These psychological obstacles prevent countless individuals from accessing the proven therapeutic benefits of treatment, including tissue oxygenation, reduced inflammation and accelerating healing and recovery.

Sanso2's revolutionary engineering breakthrough eliminates these barriers entirely, opening the door for a broader patient population to experience the transformation benefits of HBOT.

“No medications. No downtime. Just enhanced oxygen and everyday recovery made easy – in an environment that is comfortable for all,” said Sanso2 President and former NFL player Sean James. “We’re proud to introduce Japan’s most trusted oxygen therapy technology to the U.S. market.”

Sanso2’s mild hyperbaric oxygen therapy spaces are manufactured in Japan under rigorous quality-control standards, ensuring airtight performance and consistent pressure. The result is a safe, durable and user-friendly hyperbaric experience that outperforms traditional soft-shell models. Sanso2’s modular panel build allows hyperbaric therapy to be installed in places other brands cannot, fitting through standard U.S. doorways.

Engineered for Precision and Comfort

According to Transparency Market Research, the global hyperbaric oxygen therapy devices market is expected to reach an estimated $7.3 billion by 2028. Sanso2 addresses critical adoption barriers that have limited mainstream integration, positioning the brand at the forefront of an industry experiencing explosive growth.

Built for both private and commercial use, Sanso2 delivers modern spaces that optimize oxygen absorption while maintaining maximum safety and comfort. Designed for easy setup and built from galvanized steel for long-term reliability, Sanso2 products are redefining how individuals, athletes and wellness professionals experience recovery, relaxation and performance enhancement.

After suffering a triceps tear at 55, James discovered regular O2 Box sessions accelerated his recovery beyond medical expectations.

“As soon as I experienced the tremendous impact the treatments had on my own recovery, I knew we had to bring this technology to America and fundamentally change how people experience oxygen therapy,” said James. “Americans avoid hyperbaric oxygen therapy because they picture coffin-like capsules. I'm claustrophobic myself, but these spaces are different. Spacious, comfortable and built for life."

From professional athletes to the general public, the benefits of mild hyperbaric oxygen therapy have a significant impact on performance and quality of life.

“Oxygen therapy is one of the most underrated recovery tools. Mild hyperbaric therapy increases oxygen delivery to tissues, which enhances cellular repair, focus and energy regulation. It is a real, measurable edge,” said Matt Burke, Personal Trainer and Influencer.

“Recovery has always been part of my game plan. Sanso2's mild hyperbaric oxygen therapy keeps me at my best by getting oxygen deep into the body, allowing me to train harder, recover faster and perform at the highest level,” said Brad Jones, former NFL player and Super Bowl Champion.
