Himeji station is the gateway to UNESCO World Heritage Site, Himeji Castle. It is very popular day trip destination from Kobe and Osaka. You can get Himeji by JR trains, Shinkansen and Sanyo / Hanshin Railway.
Himeji castle is National Treasure, National Heritage Building, one of the best 100 castles in Japan and UNESCO World Heritage Site. I think this castle is most well known and popular castle in Japan and I believe everybody agree with me.
You can travel Himeji from Osaka as easy day trip. In this post, I would like to explain about the access to Himeji by several kinds of trains. Since Kobe is located on the way to Himeji, I also mention about Kobe. You can drop by when you go to Himeji easily.
