Forevertale Co., Ltd.

Representative Director Ryota Nagao

  • After graduating from Waseda University School of Commerce, after working as a PwC consultant, gained experience in auditing at Deloitte Touche Tohmatsu Tokyo Office and Deloitte Hong Kong Office.

  • After retiring from Deloitte Touche Tohmatsu in 2014, he assumed his current position.

  • Passed the U.S. CPA Examination (Maine Licensed 2007-2015)

  • Passed the Certified Internal Auditor Examination

I learned accounting for the first time when I was a freshman in college. However, at that time, I was freed from studying for exams and wanted to have fun, and for some reason the teacher was a foreigner and the intonation was subtle, so I couldn't understand the content at all (it's a complete excuse...). I was so frustrated with my initial studies that I decided I would never get an accounting job.


However, I reluctantly obtained Level 2 bookkeeping for job hunting and realized the fun of accounting.


It's really a waste to stop learning by stumbling on the first step. Because there is a world that spreads after that.


From this experience, I wanted to eliminate the first stumbling block for beginners, so I was involved in everything from planning to development and created Accounting Quest.


Our goal is to create the world's most enjoyable app for learning the basics of accounting!


Accounting can be complicated, but I made an app so that you don't have to be enthusiastic about "I'm going to study!" Please take the first step in accounting with the accounting quest.
