■Trigger for learning English
As the world went into lockdown due to the spread of the Coronavirus, I decided to try something new and make a change in my life. I started learning English and playing the piano, which I had been interested in for a long time. However, I continue to enjoy learning English and playing the piano every day.■The desire to use English practically
Then, as I was learning English, a desire to use it practically started to emerge. I realized that my field of certified public accounting and tax accounting, in which I have over ten years of experience, was the perfect fit for this desire.■Supporting foreigners starting businesses in Japan
While the Coronavirus seems to be nearing its end, the world is still in turmoil. During this situation, through providing support to those who love Japan and wish to start businesses here, encountering various cultures and values, receiving stimulation and deep thinking, I aim to connect with the world broadly rather than isolating myself.■Characteristics of our firm
