Company positioning and business
Japan Post Bank Co., Ltd. (株式会社ゆうちょ銀行, Kabushiki gaisha Yūcho Ginkō) is a Japanese bank headquartered in Tokyo. It is a corporation held by Japan Post Holdings, in which the government of Japan has a majority stake. [3]
It is a major financial institution that started in 1875 as a postal savings system, and that still today continues to operate primarily out of post office branches. It manages over ¥205 trillion of assets and offers services in almost 24,000 branches across Japan. At times in its history, it was the largest financial institution in the world. Since its conception, it has played a significant role in both making economic services to people in Japan and making investments towards the economic and industrial development of the country. [3]
Throughout the vast majority of its history, Japan Post Bank had always been fully government owned and organizationally a part of the postal system. In 2007, a bill was passed to begin the privatization of Japan Post Bank and to create separate companies to handle the distinct responsibilities of Japan Post. The government's sale of its shares in Japan Post Bank and its holding company are still ongoing. [3]
