It is a tour that traces the path of the samurais from the Warring States period to the end of the Edo period. Starting from the World Heritage Site of Nirayama, Reverberatory Furnace, we will head to the Egawa Residence through the "Path of Lord Egawa Tannan’s Contemplation." It is said that Tannan, who planned to build the Reverberatory furnace at the end of the Edo period walked the path. The small mountain that you can see after passing the residence of the Egawa family is Nirayama Castle. It was the residence of Hojo Soun during the Warring States period. Let's look at the Tagata Plain from the top of the castle mountain and think about the exploits of Yoritomo and other Kamakura samurais.
