Naomi Iwasaki / Administrative scrivener

I was born in Oita City, Oita, and graduated from the department of English at Seinan Jo Gakuin University Junior College before working as a  flight attendant at Japan Air System and Singapore Airlines. After that, I resolved to be a Certified Administrative Procedures Legal Specialist. I passed the exam in 2014, and set up practice in Shibuya, Tokyo, in April 2015. My specialty is completing the procedures necessary for acquiring documents such as business licenses, and supporting entrepreneurs in establishing a company and launching a new business. I watch high school baseball as a hobby. I have lived in Singapore for four years, and the United States for six and a half years.

I have spent my youth days in Sydney, Australia and when I had come back to Japan, I went to an international school in Yokohama. Having an experience as a foreigner in Australia and having a lot of foreign friends around, I have become interested in Visa related issues. My motto is “Ichi gon hou on” (meaning to not forget to thank people in every small deed) and will try to work with this motto.

Since graduating from university, I have been engaged in research on the history of Japan and China, especially the history of East Asian medicine. I still love history, but it is even more interesting to hear the stories of people from overseas who are trying to start a new business and new life in Japan. I find it very rewarding to support such people and they give me a lot of energy every day.

Mihori Inoue / Administrative scrivener assistant

After graduating from university, I worked as a flight attendant at ANA airline from 2005 to 2011.  After I left ANA, I worked as a fixed-term employee at the Ministry of Education in 2011.  Then I stayed home to take care of my child.  The working experience at the Ministry of Education made me interested in education of children.  I obtained a qualification of childcare worker by self-taught.  I like writing and learning new things.  I enjoy working at the Kaisha-Express law office.  While learning through the work daily, I hope I will provide strong support for customers.  Best regard.
