2015
Became interested in cryptocurrencies and discovered BTC and ADA.
Since 2015, I have been interested in Bitcoin and blockchain technology. Through Cardano’s presale, I discovered ADA and gradually began researching the Cardano blockchain and Charles.
First Charles
At the Cardano Launch Event in Shibuya
On October 14, 2017, the “CARDANO LAUNCH Event” was held in Shibuya to celebrate the exchange listing, where I met Charles for the first time.
Learning English with Charles Videos
Charles Saw It! I Even Got a Retweet
While gathering information, I strongly realized the importance of English skills. Using YouTube videos featuring Charles as study material, I continuously watched them to learn English, cryptocurrency, and blockchain technology — while also getting to know Charles’s personality and character.
When I tweeted on Twitter (X) about how difficult this work was, Charles unexpectedly retweeted it with words of praise!! (“I’m extremely proud of you…” — a compliment I was honored to receive.)
2018 Crypto Bubble Collapse
Believing in Cardano’s Future After the Bubble Burst
On June 26, 2018, I attended the Japan Blockchain Conference.
On September 30, 2018, I attended the 1st Anniversary Meetup celebrating the launch of Cardano ADA in Shinjuku, where I reunited with Charles.
Keeping Up with Information in Difficult Times
Still Believing…
I participated in events whenever possible, such as a Daedalus study session in Machida, Tokyo, and a study meeting in Iidabashi just before the snapshot, striving to gather information and stay up to date.
2019 Becoming an Stake Pool Operator
Learning to Become a Stake Pool Operator
From 2019, I began aiming to become a Cardano stake pool operator. Although I had no idea where to start, I began teaching myself Linux and server administration on my own. (At the time, my knowledge was limited to HTML, CSS, PHP, and MySQL.)
In December 2019, I completed my registration as a pool operator with the Cardano Foundation. I joined the testnet from Epoch 11 and have continued ever since. (As of May 25, 2026, I have successfully produced more than 15,000 blocks.)
Received Special Thanks from IOHK
On March 14, 2020, on Twitter (X)
At a time when I was close to giving up due to the steady and demanding work as an operator, I received Special Thanks from IOHK, which gave me the motivation to keep moving forward.
I will continue working hard from here on. Thank you for your continued support.
Get Started with Nekota ADA Pool
