I was born in 1962 and brought up in Tokyo, Japan. I am a native Tokyoite, received an education in Tokyo. Since graduation from a school of economics at Tokyo University, I had worked for a multi-national trading firm for more than 30 years and then jumped into the tourism industry in 2018. During my long business career, I had visited more than 30 countries and 60 cities (including stationing in New York, Hong Kong, and Beijing) worldwide to learn international communication. This experience made me realize the importance of understanding my own cultural background.​


After 3 years’ experience as a freelance tour guide, I decided to expand my business for my fellow tour guides, and set up a new company 'ZENflow Planning LLC' at the end of 2021. This company is officially registered as a category-3 type travel company in Japan. My private guiding service 'Japan Culture Guide' is still active under the name of this company now.
