The journey that inspired MTJ – Japan, 1989.
MTJ was founded by Italian entrepreneur Mariateresa Agusto, who has lived in Japan since 2006. When she first visited the country in 1989, it was in the early days of international tourism when many foreign travelers were there primarily for business.
Welcomed into the home of a Japanese friend and her family, Mariateresa experienced Japan from a local viewpoint; sharing meals, everyday rituals and personal encounters revealed to her a country shaped by timeless traditions, genuine hospitality, and remarkable beauty. She was left wondering why so few global travelers were discovering this Japan.
And so, a dream was born: to help others immerse themselves in the country she had fallen in love with.

The impacts of that first visit stayed with her and she returned whenever she could, determined to understand Japan beyond the perspective of the average visitor.
In the years that followed, she was selected for the European Unionās Executive Training Programme, an initiative created to strengthen business and cultural understanding between Europe and Japan. Through the program, she studied management, entrepreneurship and business administration primarily at Waseda University in Tokyo, complemented by specialized modules at leading European institutions.
The experience deepened her understanding of Japan, international business, and the importance of building lasting cross-cultural connections.

All of this time visiting and studying in-destination led to her dream becoming a reality in 2009, when she officially launched MTJ.
Today, Mariateresa continues to lead the organization, ensuring that every journey remains true to the vision behind its creation: helping travelers from around the world discover the same, authentic Japan she first discovered decades ago.
