Mochibun kaisha

Mochibun kaisha (持分会社) are a class of corporations under Japanese law.[1] While mochibun kaisha have legal personality as corporations, their internal functions are similar to partnerships, as they are both owned and operated by a single group of members (社員, shain).


There are three types of mochibun kaisha:

Mochibun kaisha are formed by preparing articles of incorporation and depositing the articles with a local Legal Affairs Bureau.

The Japanese civil code also provides for partnerships (組合, kumiai), a different type of business organization. Civil code partnerships lack legal personality and are mainly used for investment funds and professional firms.
