What is 'Yugen Kaisha - YK'?

Yugen kaisha (YKA) is a type of limited liability company that could be established in Japan from 1940 through early 2006. The Companies Act enacted in Japan in June 2005 abolished the YK business form. The law changed most YKs into KKs, or kabushiki kaisha, a joint stock company, which is the most common business form in Japan. The corporation law also changed the corporate governance of YKs.

BREAKING DOWN 'Yugen Kaisha - YK'

The YK was based on the German GmbH, a limited liability company and the most common form of corporation in Germany. Japan's YK structure was commonly used by small businesses and could have a maximum of 50 shareholders. The shareholders, called members, were collectively required to contribute 3 million yen in capital. YKs were required to have one director, but they did not need to have a full board of directors. After the Companies Act that became effective on May 1, 2006, no new YK could be formed, and the structure was replaced by godo gaisha.

The Four Forms of Japan's Corporate Entities

  1. Gomei kaisha (a partnership)
  2. Goshi kaisha (a limited partnership)
  3. Yugen kaisha (a limited liability company)
  4. Kabushiki kaisha replaced by godo gaisha (a joint stock company)

A yugen kaisha could have been considered similar to a subchapter S corporation, (a limited liability company (LLC) or partnership in the United States while a KK is a standard corporation). The accounting, capitalization and procedural requirements for a YK are much less strict than those for a KK. The owners of a YK have limited liability, but they also are restricted in the transfer of shares. The company cannot offer shares to the public.

Japan is a nation of small businesses. According to David Luhmen or Luhmen.org, 70% of all Japanese companies have fewer than 20 employees, and most Japanese companies are formed as KK rather than YKs. KKs are considered larger and more prestigious in Japan, which is an image-conscious nation where appearances are important.

Capitalization Requirements for KKs and YKs

The capitalization requirements for KK's and YKs changed in 1991. Before 1991, YK, a limited liability company, could be formed with approximately $1,000. After 1991, the minimum capitalization amount was changed to $30,000 (with one dollar equaling ¥100). In addition, at the same time, the minimum capitalization amount for a KK, a standard corporation, increased from about $4,000 to $100,000. 

Because of its simplified structure and relatively lax incorporation requirements, the YK form is associated with small businesses. However, some larger companies have used the form, for example, ExxonMobil's main Japanese subsidiary is a YK.
