Fought as a UFC fighter. Researches as a biohacker. And now, sat behind the mic on French combat sports media. During a trip to Nice for the Hololife Summit Côte d'Azur 2026, Tateki Matsuda appeared on JAB Life's "Ground & Talk" — the French-language MMA platform co-hosted by Boxing Squad head coach Aldric Cassata and former RMC Sport journalist Alexandre Herbinet. Sharing the episode with UFC fighter Axel Sola, fresh off a Fight of the Night at UFC London, Tateki discussed his career in the Octagon, the evolution of Japanese MMA, and his mission to bridge combat sports and sports science at the international level.

What happens when over 300 entrepreneurs, investors, doctors, and wellness leaders from 35+ countries gather in Nice and Monaco to rethink longevity? Inside the HOLOLIFE Longevity Côte d’Azur 2026 Summit, Tateki Matsuda breaks down the science, technology, and practical biohacks that are moving wellness beyond hype and into evidence-backed human optimization.

As a biohacker and former UFC fighter, I spend my days analyzing data, tracking recovery, and optimizing human performance. But let’s be honest: life is rarely a perfectly controlled experiment.

In the halls of MIT, amidst discussions on cutting-edge biology, a critical question arises: "Where does all this science go?" While we pour $10.6 trillion annually into global healthcare, life expectancy in developed nations is stagnating. We are paying more to stay sick. This article explores the "Sick Care Paradox," the metabolic roots of chronic disease, and the emerging $6.3 trillion Wellness Economy that offers a path from managing illness to creating health.

Stop chasing time—let it come to you. At the Hololife Summit 2025, I shared how ancient Japanese wisdom and modern science redefine longevity. From synchronizing biological rhythms to navigating the 'social time curve,' discover why true optimization is about harmony, not control.

"We're living longer, but breaking earlier." This is the resilience gap. My work explores how intentional movement, breathing, and embodied focus can rewire the nervous system to facilitate stress adaptation and enhance long-term performance.

The core philosophy is simple: "You don't train to resist. You train to respond."

My approach integrates Eastern martial principles like

Tanden (丹田)—your neurological control center—with Western neuroscience to achieve enhanced stability and improved autonomic balance.

Ultimately, true resilience is anchored by Kokorozashi (志), or ambition with purpose. When your mind has a clear purpose, your body finds natural stability.

Valentine's Day. The rest of the world is fighting for overpriced reservations and rushed service. I am in the kitchen.

Inside my 4-course Valentine's protocol: a clean carrot potage, fresh sea bass, single-origin Peruvian chocolate, and a little bit of calculated rebellion—Carbonara de Zucca. Tradition meets experimentation. Respect the roots, bend the rules.

This isn't about finding the hottest new spot in town. This is about a ritual.

For my wife’s birthday, I step into the Tatekitchen to prepare a four-course experience designed to maintain "freshness" in our lives. We don't do commercial anniversaries; we do technique and high-grade ingredients.

Inside this year’s birthday protocol:

• Antipasti: A French-style mushroom soup inspired by a summer trip to Helsinki.

• Primo: Hand-made 100% semolina pappardelle with sushi-grade seafood and sea urchin.

• Secondo: Denver steak seared in cast iron and finished in the oven, wrapped in caul fat.

• Dolce: Siena Farm apples elevated by Madagascar vanilla bean vodka.

No dress code, no crowds—just the kids in their pajamas and the best food in Boston, served right at our table.

How you start the year dictates how you finish it. Inside our Osechi 2026: Sourcing premium saku blocks (Hon Maguro, Kinmedai) from Sakanaya Newton, my wife’s traditional Onishime, and the intimate celebration with our Japanese school community.

"Life doesn’t move forward from endless thinking." After a year of pouring everything into Kokorozashi and the Hololife Summit, I realized that constant output creates noise. My word for 2026 is 調 (Totonou). It’s not about working harder—it’s about closing the mental loops and finding true alignment.

"Today is the last day of matsutake season," Chef Sato said. The three of us - me, Ayumi, Nanami - looked at each other. We just got blessed. HOLOLIFE Summit Tokyo was finished. Sold out, fantastic energy, everything we worked for. And now we're sitting at Hyakuyaku, about to experience omakase at one of Tokyo's most profound restaurants. I could have celebrated alone. But success means nothing if you don't share it with the people who believed when it was just an idea.

The fabric was softer than normal clothing. Way softer. This shirt at ENWA was made from jūnihitoe-inspired kimono - the twelve-layered robes imperial court ladies wore 1000 years ago. I bought it. Six hours later, I was sitting in the grittiest ramen shop in Tokyo with my preschool buddies, eating rebanira and not caring about my macros. Same day. Complete opposite energy. This is the real Tokyo story.
