 Welcome! My name is Moses Dubien and I am the founder and head teacher at OPEN Eikaiwa. With my years of teaching experience and my qualifications I want to improve your speaking and writing in English! Maybe you are working at a restaurant with many English speaking customers or maybe you are a product sale manager at a duty free store. Each person has their own unique needs and wants when learning English. Knowing this, I will work hard to make sure that your lessons are designed with you in mind. Lastly, although we specialize in business English, all learners are welcome!

To get started, I recommend you sign up with your email to receive your free PDF copy of "Speak English with Confidence" to learn how to start becoming fluent in English.


Moses Dubien, M.Ed. (Master of Education)


I was looking for a teacher who was qualified to teach English. However, I couldn't find it right away, so when I consulted with an American I knew, I was introduced to "Open English Conversation" based on my qualifications and experience in English education. This was my first time to teach online, but I am very happy to have taken 6 hours including experience to this day.
I feel that I am using my time to the fullest.

The teachers are very friendly and give us solid and enjoyable lessons. If you want to start studying English conversation, have a practice opportunity, but are wondering what to do, try "Open English Conversation" rather than wasting your lost time and take a quick step. It is recommended.
