The Author's Journey

Erika Yamaguchi, an empowered solo entrepreneur and the founder of Atelier ERICA, was born in Tokyo in 1990.

Her belief that writing serves as a lifeline propelled her to launch Self0, which she revitalized in 2022. The experience of loss deepened her commitment to her mission, transforming her journey into one of empowerment and purpose.
