SORATOBU Origins
March, 2019
Founder of SORATOBU, Taisei Yamada obtains his PPL, after graduating college.
He returns to Japan to work his corporate job in Nagoya, Japan
October, 2021
Taisei quits his corporate job to pursue a career in web development in Tokyo, Japan
Being a bit burnt out from corporate, he remembers he is a pilot, and wants to fly for fun in Tokyo.
He starts by embarking on his FAA → JCAB License conversion process, but due to the daunting process he once gives up and focuses on his career
Sometime in 2023
After nurturing his web development skills, Taisei falls victim to tech burnout.
He once again attempts his license conversion... and it works!
Taisei joins a flight club in Tokyo called Skyshaft in order to embark on his private pilot journey in Japan
February 2024
Taisei takes the Cessna 172 owned by Skyshaft, and with an instructor he takes the plane up into downtown Tokyo.
He was mesmerized, and confirms he wants to share his adventures to people around the world.
July 2025 (and present)
Taisei founds SORATOBU under J-TEC Ltd, and is currently the developer and organizer for the world's first digital platform dedicated to showing everything you need to know about general aviation in Japan
