About 800 armor-clad warriors are divided into the Shingen Takeda army and the Kenshin Uesugi army, and reproduce the greatest battle in the Age of Civil Wars happened in Kawanakajima, Shinshu(Nagano Pref.).

Since they have the place name Kawanakajima in Isawa-cho, this event was planned in 1979 and this year they are going to have the 27th battle.

They also have the Inatomi-style gunnery party from Yonezawa han(Yamagata Pref.)and their demonstration, which has 400 years of history, and Yonezawa was once ruled by Kenshin Uesugi. Their firearms were called “Ozutsu(large rifle)”, which has the largest caliber as a gun with a stock, and if those who are not exercising firing, the shot-reaction flow them back and might break their shoulder bone.

The weight of the gun is more than 20 kg, without exercising you cannot even aim at a target. (The writer was not able to hold right the gun at all. He is in his 30s, 180cm tall, and weighs 75 kg. Quite a healthy man.
