High atop a mountain lies the ruins of Kasugayama Castle, formerly the great fortress of Uesugi Kenshin (1530-1578). The warlord is often named as a favorite by those interested in Japan's Warring States Era.
Although what remains of the castle grounds are but ruins, it is easy to understand the strategic vision behind its location and construction. Uesugi Kenshin was truly the Lord of the Mountain and all he could see.
To enjoy the site requires a good deal of walking; hence, I would encourage you to take a taxi from Naoetsu Station off the Shin’etsu Line from Niigata. I have seen the Kasugayama Station recommended online, but be forewarned there are no buses, taxis, or maps at that particular station.
If you walk, it would require nearly an hour to reach the castle ruins. I would reserve your personal, daily Japan walking allotment to use on the castle grounds. Hike the trails, enjoy the surroundings, and even meditate. Then, once done, call a taxi to take you back to Naoetsu Station. Easy.
