Ambassador interview: Tetsuyuki Oishi


Part eight of our interview series with Bitnation’s international ambassadors, this time with Tetsu Oishi from Japan, now residing in Vietnam.


Erik: Hey Tetsu, tell us a bit about yourself, where are you from, what do you do and what got you into crypto technologies and liberty?


Tetsu: Hi, I’ve studied computer networks and the year I entered university (1994) was also when Netscape Navigator was getting started. I’ve been facing my workstation from morning till evening every day at that time, to make servers working.

I chose my first job as consultant at Accenture, because the internet can change business everywhere in the world, and I wanted to help make clients aware of the impact of the digital age. But that was too early for established companies. So I quit, and started and a social networking service like LinkedIn / Facebook with students.

After that I returned to my consulting job and started writing books and blogs. I wrote 20 books that have been published, about critical thinking, problem solving and developing your career. Some books have fortunately been bestsellers. That is why I have 16,000 followers on Twitter.


Through 2009, the financial crisis and the 2011 earthquake disaster, I was loosing my hopes for the future. I was very doubtful over what happened in Japan.

The government hasn’t changed at all, nothing was learned in 2009 and 2011. They were printing ever more money and spent taxpayer money on welfare and building new roads, bridges and even a dam. I thought it was time to leave Japan.


I was so disappointed on what the government was doing, I started doubting our concept of governance itself: Centralization, the nation state and law enforcement. So I decided to become a digital nomad, someone who is “geographically, financially and organizationally independent”. That’s why I am living in Vietnam now.

I became aware of Bitcoin in early 2011 while researching community currencies. My first impression of Bitcoin was bad. I thought “you earn them in online casinos!”  I ignored Bitcion at that time.

In 2013, Bitcoin was a hot topic on the news media. So I took notice of Bitcon again and found that this technology is totally disruptive. I read the Satoshi protocols, heard about it from engineers and community members convinced me that Bitcoin can change the world.


I love the decentralized concept laying in the Blockchain. I understood instantly that the Blockchain can be a basic infrastructure for governance, contracts, law, and even nations. The Blockchain is not just for money. It’s there for brandnew governance structures, replacing the nation state concept from the Napoleon era.

I was so excited and decided that I will help the world to change itself through the blockchain, to rebuild itself with decentralized governance. Now I am helping entrepreneurs in Japan and, as a blogger, I am a Bitcoin evangelist and introduce my people to blockchain technologies. It is quite natural that I have become an ambassador of Bitnation.


Erik: What was your first point of contact with Bitnation and what has motivated you the most to become Bitnation ambassador?


Tetsu: I was convinced blockchain can replace some functions which governments do. I imagined functions such as marriage, death, notary, land registration, company registration, even a birth registration. And I made some research on these topics. Bitnation was the result of my google search and seems perfectly matching with what I was thinking of before. My motivation is to make governance better, decentralized and fair.


Erik: Can you tell us about how digital nomads like you could profit from voluntary, global governance services? How could people in Vietnam use Bitnation?


Tetsu: Digital nomads like me know that national borders are imaginary. Our activities are global, but most governance systems are still for locals only. The government marriage system is one of the most obsolete systems today. Marriage is a very personal matter, but it is being enforced by governments, and the laws are so different in each country.

In Japan, we cannot choose different family names by law: Woman have to change their names. Also, sexual minorities are fighting to get their rights for marriage. Imagine if there was the blockchain that certifies their marriage, not through the power of a national authority, but by the power of the people. The Internet people of the world. That’s why we actually embedded our marriage in the blockchain, without notifying the Japanese government.


Erik: Do you think gay and transgender activists should start empowering blockchain marriage services like Bitnation’s DApp BitMarriage rather than putting their efforts into political activism?


Tetsu: Both. You know in the United States, they won the political right for marriage, but other countries haven’t achieved the same yet.

If Bitnation’s marriage is growing and a certain number of people use it, even though that certificate isn’t legal to nation-states, it will be a clear message that many people married on the blockchain and it is working without any further problems. It eventually helps political activism to change the established law.


Erik: Thanks for your time and thoughts. We appreciate all your contributions and hope to hear more from you soon Tetsu!
