Working in a multinational company and in a multicultural environment the medium of communication is English and there is no pressing need to speak in Japanese or improve my Japanese skills as far as work environment is concerned. However living in Japan nearly about 10 years I was very much embarrassed about my poor Japanese skill. It’s not that I haven’t tried to learn Japanese, I have tried group studies, self study etc. leaned base meaning and stroakorder of about 2000 Kanjies following J.W.Heisig’s method. However none of these helped me to grow to a level where I could confidently interact in Japanese. Maybe I was following incorrect methods when it come to improving conversational skills, properly the focus was not good enough, the interactions were inadequate or perhaps the necessity factor was relatively low. Finally I came to the realization that may be for me (a person who doesn’t have necessity to interact in Japanese in day-today life, doesn’t have too many Japanese friends or the social interactions with Japanese people are not high) a method in which a direct conversational interaction is highly important and this is the point I started searching for Japanese teachers who can give interactive lessons.
I requested my friends and colleagues to suggest teachers from their known circle. I also tried to consult professional Japanese teaching centers however quickly realized that there is no very much room for customizing the lesson plans based on my skill level and requirements.
It was few months ago one of my ex-college shared me Sachi Sans contact number. In our first meeting itself I had very positive feeling. She was very much focused on trying to understand my requirement, skill level and was very open to discuss and customize lesson plans. She was also very flexible in terms of study tools as well. Being a computer architect one of my requirements was to use digital medium and tools for leaning and preferred to reduce the usage of hard copies. Sachi San was so quick in searching and figuring out those digital tools that she would use to aid the lessons. I was surprised that in quick time she bought an iPad and all tools she needed and suggested me to use those tools.
One of the amazing quality I observed in Sachi San was the ability to drive you through right path. When I started, I wanted to fly fast and set my goal as completing N3 in 6 months. Sachi San realized it quickly that I am not equipped with the skills needed to be ready for N3. Instead of saying it on the face, she tactfully gave me some sample questions and made me realize that it is too big of a target for me at that stage.
The best part in Sachi Sans teaching style is she is so calm and flexible yet strict and focused. You will get lot of opportunities to have detailed conversation, discuss your requirements and align the study plans based on it. 

As far as I am concerned, before attending Sachi Sans lessons I had very little confidence to converse in Japanese even though I was able to understand the gist of basic conversations in Japanese. With the help of Sachi San I could quickly gain confidence and start interacting with people in Japanese. The more I started interacting it helped go give a rapid progression to my learning. To give you an example, after joining Sachi Sans lessons, I managed to talk with real estate agents in Japanese (although my language skill is yet not that great) and bought a land in Tokyo. You can imagine the requirement to interact in Japanese especially when dealing with these kinds of matters.  I am extremely happy that I was able to manage those conversations myself. Now I am progressing in the discussions with construction companies to build a house in fact. I am taking this example not to say I made a rapid progress instead I would like to highlight the confidence level I gained in quick time. 
Overall I am a very satisfied student of Sachi San.
