Arai Masumi

I am originally from Tokyo.
I Joined JTB Co., Ltd. and worked there as a travel adviser covering a wide range of responsibilities including domestic and overseas travel, weddings, and training subordinates.
Afterwards, I also continued to establish experience in accounting, general affairs, personnel affairs, payroll calculation, etc., and learning the workings of company management.
In order to support small and medium-sized enterprises, I left JCB and established Happy Combi Co., Ltd. with my husband.
Arai Social Insurance Workers’ Office was made to further specialize in the support of the labor field.
After opening the Social Insurance Workers’ Office,
we handle a wide range of practices, such as social insurance procedures, pension counseling,
employment rule diagnosis and preparation, grant application support, and one-parent correspondence.
Currently, I serve as a director of an incorporated corporation that raises awareness to subsidies available to small and medium-sized enterprises, and we have established a network with over 100 social insurance workers while continuing to conduct public awareness activities.
I am also a mother of two boys and enjoy playing the flute as a hobby.
