日本的JR（Japan Railways Group），正式名稱為“日本鐵道公司集團”，是日本最大的鐵路公司集團。成立於1987年4月1日，由原來的日本國有鐵道公司（JNR，日本國有鐵道，Nihon Kokuyū Tetsudō）私有化後拆分而成。JNR在二戰後經歷數十年的運營，但由於財政問題和效率低下，最終在1987年4月1日進行私有化改組，成立JR集團。JR在日本的鐵路交通中扮演著重要角色，提供廣泛的客運和貨運服務，覆蓋全國各地。

集團由七個地區性公司組成，分別負責不同區域的鐵路運輸業務，分別為東日本旅客鐵道公司（JR East/綠色）、東海旅客鐵道公司（JR-Central/橙色）、西日本旅客鐵道公司（JR West/藍色）、北海道旅客鐵道公司（JR Hokkaido/淺綠色）、四國旅客鐵道公司（JR Shikoku/淺藍色）、九州旅客鐵道公司（JR Kyushu/紅色）和日本貨物鐵道公司（JR Freight/灰藍色）。這些公司都各自獨立營運，也沒有彼此交叉持股，因設立的原因相同，因此被統稱為JR集團。

其運營網絡覆蓋整個日本，包括新幹線、在來線（傳統鐵路線）和一些城市的地鐵路線。以下是一些主要的JR地鐵站和路線。

1.東日本旅客鐵道公司（JR East）:東京站（Tokyo Station）是日本最大的鐵路樞紐之一，連接東海道新幹線、山手線、中央線、總武線等多條重要路線。新宿站（Shinjuku Station）是世界最繁忙的火車站之一，連接山手線、中央線、總武線等多條線路。上野站（Ueno Station）連接東北新幹線、上越新幹線、山手線等重要路線。品川站（Shinagawa Station）連接東海道新幹線、山手線、京濱東北線等，是東京的重要交通樞紐。

其廣泛的鐵路網絡、現代化的車站設施和高效的服務，在日本的公共交通系統中扮演著不可或缺的角色。從新幹線的高速列車到城市內的地鐵路線，JR為日本的日常通勤和長途旅行提供準時便利和可靠的選擇。

The Japan Railways Group (JR), officially known as the Japan Railways Group, is the largest railway company group in Japan. It was established on April 1, 1987, following the privatization and division of the former Japanese National Railways (JNR, Nihon Kokuyū Tetsudō). JNR had been in operation for several decades after World War II, but due to financial problems and inefficiency, it was ultimately privatized and reorganized into the JR Group on April 1, 1987. JR plays a crucial role in Japan's railway transportation, providing extensive passenger and freight services nationwide.

The group consists of seven regional companies, each responsible for railway transportation in different areas. These companies are: East Japan Railway Company (JR East, represented by green), Central Japan Railway Company (JR Central, orange), West Japan Railway Company (JR West, blue), Hokkaido Railway Company (JR Hokkaido, light green), Shikoku Railway Company (JR Shikoku, light blue), Kyushu Railway Company (JR Kyushu, red), and Japan Freight Railway Company (JR Freight, gray-blue). These companies operate independently and do not hold shares in each other, but they are collectively referred to as the JR Group due to their shared origins.
