Rail transit is a primary transport mode in Tokyo and has become the backbone of its urban development. Tokyo rail transit networks consist of the subway in the central area, private railways in the suburban area, and Japan Railway (JR) in both central and suburban areas. Prior research revealed that JR has better coordination of transit node functions and station-area development than subway and private railway stations, but how Tokyo's JR station-area development integrates with its network growth is less explored. This work investigates how JR station-area development grows in tandem with network expansion, by revisiting different historical phases. The results show that, in the beginning of the twentieth century, JR connected major urban nodes in both central and suburban Tokyo, and therefore became the skeleton of Tokyo's transit systems. During the post-earthquake and post-war period, central subway and suburban private railways gradually met JR on the Yamanote line, enabling the major interchange stations to develop into urban centers. In the 1960s, JR increased its services to alleviate passenger congestion and undertook grade separation projects to reduce conflicts with road networks. The 1987 JR privatization marked a turning point of massive station-area redevelopment. JR station areas have been transformed from underutilized industrial land into high-density commercial use, and major JR stations were comprehensively replanned for identity and place-making. After a centennial development, JR stations have become important interchange and express-service nodes on Tokyo transit networks with intensive land use and different urban functions. The Tokyo JR case can provide insights for metropolitan cities on how to integrate rail transit infrastructure with station-area development, including matching critical nodes in transit networks with urban functions and high-density land use and connecting these urban functions through express line services.

轨道交通是东京的主要交通方式，已成为其城市发展的支柱。东京的轨道交通网络由中心地区的地铁、郊区的私营铁路以及中心和郊区的日本铁路（JR）组成。先前的研究表明，与地铁和私营铁路站相比，JR 对交通节点功能和站区发展的协调性更好，但东京的 JR 站区发展如何与其网络增长相结合的探索较少。这项工作通过重新审视不同的历史阶段，调查了 JR 车站区域的发展如何随着网络扩张而增长。结果表明，在 20 世纪初，JR 连接了东京中部和郊区的主要城市节点，因此成为东京的骨架。的交通系统。地震后和战后时期，中央地铁和市郊私营铁路逐渐在山手线上与JR相接，使主要换乘站发展成为城市中心。在 1960 年代，JR 增加了服务以缓解乘客拥堵，并开展了坡度分离项目以减少与道路网络的冲突。1987 年 JR 私有化标志着大规模车站区重建的转折点。JR 站区已从未充分利用的工业用地转变为高密度商业用地，对主要 JR 站进行了全面重新规划，以进行身份​​和场所营造。经过百年的发展，JR车站已成为东京交通网络上重要的换乘和快速服务节点，土地利用密集，城市功能各异。
