Episode Insights


In the first episode, Keito reflects on his early failures, revealing how his poor scores put his chances of graduating high school in jeopardy.

The series will explore his first year of studying for re-examinations, focusing on the determination needed while living away from home.

Keito Kujime's Profile


Keito Kujime is a doctor, entrepreneur, and vocalist. As the CEO of Kyoritsu Doctors Lab, he also leads the skincare brand 'KUJIME' and the music group 'O.K.THANKS.' After facing struggles during his high school years, Keito achieved the remarkable feat of entering medical school after three years of retries. His philosophy emphasizes that perfection isn’t necessary; persistence and personal pace are key to success. Keito creates content that acts as a companion to those who aspire to challenge themselves across music, video, and literature.

Quote from Keito:
"During my studying, the light always seemed far away. However, I believe the higher the mountain, the more unique the view from the summit will be for each individual. You don’t need to be perfect. Being a little slower than others is okay. Take your time, step by step, to reach the top, and I hope you experience a perspective that belongs only to you. This project and the music will serve as a tailwind for that first step."

Future Developments


Alongside releasing the 10-episode knowledge series on YouTube, efforts are underway to publish a book documenting this journey as a documentary. We envision the possibility of visual storytelling in the future as we expand the content.
