Tetsuya “Tez” Miyamoto

Manhattan, New York 2016

Hello, my name is Tetsuya “Tez” Miyamoto, I am a math teacher and the inventor of the Puzzles That Make You Smarter ™️, KENKEN®︎, and a scuba diver (I dived 1000 times around the world.)

I was born in Takatsuki, Osaka, Japan in a poor family on November 25th, 1959.  Since my parents lived a normal live, I planned to live a normal life as well.

At the age of 14, I woke up one morning and realized, I was my own person with my own goals and dreams, and turned a deaf ear to everyone.  Not even my parents could tell me what to do. I struggled and fumbled for my own ways of studying and living, but from age 14-19, was my dark ages, I thought about committing suicide everyday, and probably thought out 100 ways to kill myself.  I had no confidence of getting accepted into a high school that I wanted to go, so I went to a lower level high school. But then, I dropped out at age 16 when I learned about Dai-ken 大検, an university entrance qualification exam, or defined as certificate for Students Achieving the Proficiency Level of Upper Secondary School Graduates.

Age 28. I was working as a teacher at one of the biggest cram schools in Japan. These kids are now over 40, and the ones I reunited recently are all living happy lives; doctors, lawyers, dealers, artists, etc.

After three years of self studying, I went to Waseda University, School of Humanities and Social Sciences in Tokyo, and did blue colored part time jobs such as newspaper delivery, working at a fast-food store, and an automotive factory, to earn my tuition and life expenses, and then I became a teacher at a cram school for the first time.

Although I had never been interested in education for children, I totally got indulged.  After graduating Waseda University,  I tried to get out of the field of cram schools, but ironically I failed all of the exams in my job hunting for Japanese companies, ending up finally getting a job at the best cram school called TAP, back then in Japan.  Later on, after I worked at another prestigious cram school called SapiX, in 1993, I set up my own; Miyamoto Sansu Kyoshitu (Mathematics Classroom) in Yokohama, Kanagawa, Japan.

My life was already very happy with my classroom being filled up and an approx. 400 students waiting in line to enroll into my 20 kids first come first served limited capacity class, but suddenly in 2009, my instinct told me that I wanted to move my classroom to the center of Japan, Tokyo Station! So right away, I moved it to a three minute walking distance from the Nihonbashi exit of Tokyo Station.

In 2015, my instinct moved me again. I suddenly wanted to teach mathematics in the center of the world.  So I applied for a green card, and was accepted in an unbelievable speed of only 6 months with the same level green card as John Lennon, Yoko Ono, and those people who have shown extraordinary abilities in the arts, athletics, education or the sciences; the E-11 Green Card. I wish to meet Yoko Ono one day.
