I’m a linguist, language teacher, and translator. I help professionals, heritage learners, and curious individuals use Japanese more confidently—whether it’s for work, travel, or understanding their own family history.
If you’ve ever felt lost in translation or unsure of what’s appropriate to say, you’re not alone. I’ve been teaching for over 15 years and translating for most of my life.
Through Kokoro Communications, we make Japanese more accessible—so you can reach your goals with confidence and cultural awareness.
“Kokoro Communications' Japanese Phonetics 101 course breaks down Japanese pronunciation in easy to follow videos and accompanying materials. It's a great mix of theory and practice that would be useful not only to those earlier in their learning journey (like myself) but also those who are more advanced grammatically but wanting to sound like a native speaker.”

“I signed up for Japanese classes with Sachi, hoping to reach my goal of proficiency, in order to be able to work Japan routes as a flight attendant. I was very happy with her curated curriculum designed for my job as a flight attendant, which will help me on a day to day basis.”
— Marjorie Nadeau, Air Canada Flight Attendant
“Sachi provided translation services for my Japanese Family Registry (Koseki), and I am extremely pleased with the comprehensive and meticulous work provided. Overall, the service exceeded my expectations, delivering a thorough and precise translation that truly reflected the intricacies of my Koseki. I highly recommend Sachi and Kokoro Communications, thank you so much!”
