Japan Corporation (ヤフー株式会社, Yafū Kabushiki-gaisha) was a Japanese web services provider.

Japan merged with ZHD and its five subsidiaries, including Line Corp, to form LY Corporation.

In January 2000, it became the first stock in Japanese history to trade for more than ¥100 million per share.

[6] In July 2018, SoftBank bought $2 billion worth of shares in Yahoo!

Japan, in turn, bought nearly the same amount of stock from SoftBank.

[10][11][12] Upon integrating the two businesses and creating further platforms, the merged company aims to compete with the U.S. tech giants Google, Amazon, Facebook, and Apple and the Chinese tech giants Baidu, Alibaba, and Tencent,[11] as well as the Japanese e-commerce giant Rakuten.

[10] The merger also gives Z Holdings three additional Asian markets where Line is popular: Taiwan, Thailand, and Indonesia.

Japan was a founding member of the Japan Association of New Economy (JANE, at the time named Japan e-business association), a Japanese e-business association led by Rakuten CEO Hiroshi Mikitani, in February 2010; Rakuten later withdrew from the Japan Business Federation (Keidanren) in June 2011 and made moves to make JANE become a rival to Keidanren.

Japan withdrew from JANE in March 2012 and joined Keidanren in July 2012.
