Tsuyoshi “Yoshi” Domoto

Camp Advisor & Consultant

Yoshi was born in Sapporo but had an international upbringing, spending his childhood in Taiwan, Hong Kong (China) and South Korea until he left for the United States for University.

His passion for education was ignited in 2014 during the time when Yoshi worked for a non-profit in Honduras when he learned that his homestay sister had only four books at home. Because he believes quality education should be accessible to all, he crowdsourced a project that resulted in the establishment of the town’s first community library (e-libro project).

Yoshi has organized, managed and delivered successful summer camp programs in previous seasons in Tokyo, Nagano and Gunma prefectures as the Country Manager of a programming school for kids and also as the Director of an academic institution for international school students in Tokyo.

Yoshi currently works as an educational consultant where he advises and consults international schools, educational institutions and individual families who want to provide a quality education for their children. He holds a Masters of Education in Technology, Innovation and Education from the Harvard Graduate School of Education (MA 2017).

His fondest memories as a child were playing outdoors in the creek with friends, camping with the Cub Scouts of America, and being outside. We built makeshift rafts, explored the neighborhood, learnt about our environment, and dealt with the weather without adult supervision. His passion is to give that right to explore, play and be in nature back to the children in an educational setting. Realizing the need to for education in an outdoor environment Kai founded iForest - International Forest School in Tokyo.

In the pursuit to become a confident outdoor counselor Kai began seeking a profession in education in 2007. Starting with the U.S. Peace Corps to a MS in Early Childhood and Family Development from Missouri State University. He has worked in prominent international schools in Minato municipality and he is a board member at NPO Harmony International School, Fujisawa, Japan.

About Tokyo Children's Garden

Tokyo Children’s Garden is an innovative, Reggio Emilia-inspired bilingual preschool nestled in the heart of Tokyo. We view children as capable learners and actively embrace their thoughts and ideas in our unique, nurturing environment.

At the start of the pandemic, we temporarily closed our Tokyo campus while seeking an alternative to online sessions. Believing young children need real-life experiences, we relocated to a scenic house in the woods of Kawaguchiko, surrounded by breathtaking views of Mt. Fuji, not knowing if any of our school families would follow us.

To our delight, most of our families joined us, resulting in a memorable summer of forest fun. Since then, we have regularly offered forest school experiences in Karuizawa and are thrilled to introduce our Nature Adventure camp to new families this summer.

This year, we're fortunate to have Kai Chang and Tsuyoshi "Yoshi" Domoto lead our Karuizawa Nature Adventure in picturesque Karuizawa. Our exciting program has engaging activities and outings to spark curiosity and inspire young minds. Campers will make new friends, explore nature, and learn new things, all against the stunning backdrop of Mt. Asama. There's no better way to spend the summer!
