This is a statue of Rokkaku Sadayori which stands in Higashi Omi city, Shiga prefecture. Rokkaku Sadayori (1495-1552) was a "Daimyo" (regional lord) who ruled the southern part of Omi province in the Sengoku period (or Warring States period from mid-15th to early 17th century). He established the foundation for the powerful Rokkaku clan which later fought against Oda Nobunaga.
Oda Nobunaga (1534-1582) preferred to use "Nanban Dou Gusoku" which was created based on western armor. The statue in this photo shows Nobunaga wearing this armor with a western helmet in his left hand and a "Hinawa-ju" (matchlock gun) in his right hand. While he wore western body armor, he used Japanese style armor for the lower half of his body and his arms. This style was used to defend against bullets while enabling quick movement.
Takeda Shingen (1521-1573) was a powerful "Daimyo" (regional lord) who ruled Kai (present-day Yamanashi prefecture) and Shinano (present-day Nagano prefecture) provinces. He is one of the most famous Daimyos of the Sengoku period (or Warring States period from mid-15th to early 17th century) along with his rival Uesugi Kenshin (1530-1578) who ruled Echigo province (present-day Niigata prefecture).
