The Starting Point of Growth

I am currently struggling with many things.  

Meeting numerous philosophers with outstanding ways of thinking has led me to reflect on my past and realize that I must bring about change.  


Changing My Environment

Right now, I live in Tokyo and Kagoshima. But I want to move to San Francisco as soon as possible. 

To broaden my perspective and raise my standard of insanity, I need to step into the world quickly.  

Making the Decision Not to Do

There are so many things I need to do—school, research, startups, venture capital. 

Yet, truly exceptional philosophers often focus on just one thing. 

I must learn to make the conscious decision *not* to do certain things.  

Understanding My Own Time 

Recently, I have come to the realization that I only have 24 hours in a day. 

I must recognize my strengths, break things down, and delegate tasks when necessary.  


So, let’s grow and meet the version of myself who has raised the bar.

Hi, I'm Ryuzo.

Hello, nice to meet you.

I'm Ryuzo, a 17-year-old high school student living in Japan.

I've struggled with obsessive-compulsive disorder (OCD) for a long time.

From that experience, I began researching treatments for OCD, and now I'm working in the field of preventive medicine for mental disorders.

A brief introduction:

  • Researcher at the University of Tokyo and Waseda University

This site is where I continue to document my thoughts.
