Nirayama Castle (Nirayama-jo) was built at the end of the 15th century by the daimyo Hojo Soun. Soun lived in this castle until his death at the age of 88. It is also well-known for the struggle that the samurai of Nirayama Castle put up by barricading themselves inside for over 100 days against an attack by the hegemon Toyotomi Hideyoshi, who ruled Japan in the latter half of the 16th century. The defense against the attack put up by the samurai protecting this castle was strong and the castle did not fall easily. When all their neighboring allies were defeated, however, they surrendered. A retainer of Tokugawa Ieyasu, who subsequently came to rule Japan, moved into Nirayama Castle.
