Japan Post Co., Ltd. (Japanese: 日本ヵ政株式会社/にっぽんゆうせいかぶしきかいしゃNippon yūsei Kabushiki kaisha*/?) is the holding company for Japan's postal services, headquartered in Otemachi, Tokyo. It is often referred to as Japan Post or "JP 日本ヵ政" (JP HOLDINGS in English). Japan's various postal organizations form the "Japan Post Group" (日本ヵ政グループ; Japan Post Group) with Japan Post as its core.

Japan Post Holdings (Japanese: ニュポンド株式会社), the core corporate body of Japan Post Group, is headquartered in Tokyo and established in 2007. Its predecessor, Japan Post Public Corporation, was restructured in 2003 (as part of the restructuring of the national postal system). Japan Post oversees the group's operations, encompassing mail delivery, financial, and insurance services. Its subsidiaries include Japan Post, Japan Post Savings Bank, and Kansai Life Insurance Company. The company was listed on the Tokyo Stock Exchange in 2015.
The company has undergone several restructurings: in 2003, it was reorganized from the Postal Services Agency of the Ministry of Internal Affairs and Communications into Japan Post Public Corporation. In 2007, it completed privatization and restructuring to form a holding structure. In 2015, it promoted the listing of its financial subsidiary and improved group efficiency through capital optimization. In recent years, the company has implemented a digitalization strategy, launching the "Future Post Office" pilot project in 2022 to integrate intelligent systems to enhance the service experience. The company has been listed on the Fortune Global 500 for many consecutive years, ranking 94th in 2022.
