This is a channel on the Ikigai Diet, the secret Japanese diet to health and longevity. The diet is based on the lifestyles of the longest-lived prefectures in Japan, such as Nagano, Shiga, and Okinawa, as well as the lifestyles of Shizenha people, the Japanese naturalists. The channel covers four main topics, which are introduced in the book; diet, exercise, lifestyles, and mentality. I provide information on healthy living, especially the ones which are popular among Shizenha people in Japan.

I am Japanese living in Japan, and I have daily encounters with Shizenha people, so I can share with you what is catching on right now among the healthiest people in Japan.

A lot of people ask me about the famous Japanese "Slow Jogging" method for longevity. Here's the truth: it's basically just Zone 1 training, and you can get the exact same anti-aging benefits simply by walking. But to gain further benefits for cardio, muscle strengthening, and bone strengthening without the knee injury risks, I have come up with a "Japanese Jogging Technique" that can optimize your cardio exercise. Here is exactly how you can start doing it tomorrow.

You take your shoes off at the door (great!), but then you make a huge mistake: you put on slippers. 🏠🚫
In the West, we think slippers are cozy and harmless. But in this video, I explain why soft slippers act like "coffins" for your feet—slowly weakening your balance, dulling your brain's connection to the ground, and increasing your risk of falls as you age.
There is a reason why traditional Japanese culture encourages being truly barefoot indoors (or using a specific type of sock). Today, I’ll show you how to turn your home into a natural gym for your feet—without doing any extra exercise.

Japan is no longer #1. 📉 A viewer recently commented: "Hong Kong people live longer than you guys. How do you explain?"


For years, we believed the Japanese diet and lifestyle were the gold standard for longevity. But the data doesn't lie: Hong Kong has overtaken Japan in average life expectancy. Instead of being defensive, I decided to investigate.

What I found wasn't just about genetics. It comes down to 5 specific "hidden habits"—from the layout of their city to a morning ritual.


In this video, we explore the "Vertical Blue Zone" secrets of Hong Kong and what we can learn from our neighbors to live a happier, longer life.

The new 2026 American Dietary Guidelines are here, and they are causing a stir. But according to Dr. Shimokawa, a leading Japanese gut health expert, the biggest problem isn't what the guidelines say—it's what the image shows.

In this video, we break down why following the "Pyramid Image" blindly could wreak havoc on your gut microbiome, even if the guidelines themselves have some good points buried in the fine print. Dr. Shimokawa warns that misinterpreting these visuals could lead to an overconsumption of inflammatory meats that damage your gut lining.


Whether you follow a Carnivore, Keto, or Omnivore diet, understanding this "Fine Print" is crucial for your long-term health.

A massive 30-year study from the Harvard T.H. Chan School of Public Health has just uncovered a longevity secret that tracks over 110,000 adults—and the findings might completely change how you think about exercise.
While the Western world often obsesses over gym intensity and "no pain, no gain," Harvard researchers discovered that one specific approach to movement can lower your mortality risk by roughly 19%.
Here is the fascinating part: This "scientific breakthrough" is actually something centenarians in Okinawa and Kyotango have been doing naturally for generations. It’s not about how hard they train, but rather how they structure their movement.

Stop scrubbing away your health every morning. We are told that we need toothpaste for healthy teeth, but what if that minty-fresh habit is actually destroying your gut microbiome? At 63, I realized that sterilizing my mouth with chemicals was working against my body, so I stopped using toothpaste completely.

In the Japanese naturalist lifestyle, the mouth is considered the gateway to the gut. If you kill all the bacteria in your mouth—good and bad—you disrupt your entire immune system before breakfast.

In this video, I share the "Naturalist Dental Protocol" I use to keep my teeth strong and my gut happy—without a single drop of toothpaste.

I thought my morning routine was perfect... until a Japanese gut expert told me to STOP doing this.


Do you drink a glass of water first thing in the morning? I did too, for years. We are told it is essential for hydration after a long sleep. However, I recently watched a video by a Japanese gut health expert and was shocked to discover this might actually be a bad idea.


I was stunned because I thought I was optimizing my health. My morning routine was carefully designed around cutting-edge longevity science—optimizing my circadian rhythm, activating autophagy, and boosting gut health.


But I missed one critical action before that first glass of water.


In this video, I reveal the "missing step" you should do immediately upon waking, along with the full breakdown of my updated longevity morning routine.

Is saturated fat actually the superfood the "New Food Pyramid" claims it is? 🥩 While modern trends are pushing for higher fat intake, there is a hidden cost to your gut health and longevity that nobody is talking about.

In this video, I break down the confusion surrounding saturated fat. We look beyond the headlines to see what really happens to your gut microbiome and autophagy processes when you increase your saturated fat intake. Instead of blindly following the latest food trend, I’m sharing a time-tested Japanese Protocol that offers a smarter, more balanced path to longevity.
In this video, we cover:
