I would love to make a fight statement. On September 11(Japan time), I am fighting against So Tatsuya, Okinawa, Japan. It has been a long time since my last fight.
Thank you, Pancrase, for a great opportunity to perform in my hometown in Japan.
I've been busy with training and focused on the next fight, so have fun in the cage. Stay tuned with more detail, and we, myself, and my fans, will win together, and I know you got my back!!

OPTIMIZED LIFE
Biohacking is very good at measuring inputs and outcomes. But adaptation often happens in between. Drawing on years of self-experimentation and professional fighting, from extreme weight cuts and fasting to wearables, metabolic tracking and recovery protocols, Tateki Matsuda explores what can get lost when optimization becomes the goal itself. He connects recovery science with lessons from martial arts, including timing, distance, and the Japanese concept of Ma, the meaningful interval between actions. The goal is not to reject optimization, but to ask a better question: what should we improve, what should we protect, and what should we leave room for?
TATEKITCHEN
Nine days in Nice with the kids, one Airbnb kitchen, three nights of Tatekitchen. Octopus, Maison Barale ravioli, a whole roasted guinea fowl and a grass-fed ribeye, all from local markets at roughly a third of Boston prices. Why cooking local might be the best way to taste the South of France.

"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.
