What is Daigaisha ?
In the case capital amount of a company is 500,000,000 yen or more, it is called “Daigaisha = Large company”.
In that case the company needs to prepare enough organization to protect persons concerned.
So, the company needs to appoint at least one director + one auditor ( kan sa yaku ) + one accounting auditor ( 会計監査人 = kaikei kansa nin ).
only certified public accountant ( Konin kaikeishi ) can become accounting auditor.
Change of capital amount and Daigaisha
In the case a company ( named B inc. ) has increased capital amount to 500,000,000 yen in the middle of fiscal year, it is not ” big company = Dai kaisha =大会社 ” until next ordinary general meeting of shareholders.
June 2017 Increased capital amount to 500,000,000 yen or more.
July 2017 Decrease capital amount less than 500,000,000 ( Public notice for creditors is required. It will cost several ten thousand yen).
( In this way, B inc. can avoid becoming big company and B inc. does not need to appoint accounting auditor ).
March 2018 Fiscal year end ( as of fiscal year end, B inc. is not big company )
June 2018 General ordinary meeting of shareholders.
