Touring the home of the ninja, one encounters strange and beautiful landscapes. Surrounded by hills, the paths are like a maze.
The villages are hidden in the valleys like hidden villages, and from the sky, a complex valley topography can be seen.
This topography was formed by the erosion of the Lake Biwa Formation about 3 million years ago.
At the tip of the hill and at the entrance to the valley are the ruins of a castle, making it an ideal terrain for intercepting intruders.
There are more than 800 castle buildings in Iga and Koga, surrounded not by stone walls but by earthen mounds. Let us take you on a journey to explore the history of how this region became closely linked to the ninja organization.

The real image of the ninja was that of local samurai known as "Iga-shu" and "Kouga-shu".
During the Warring States period, autonomy developed in this region where there were no feudal lords, and the local samurai were united in autonomous organizations such as the "Iga Sokoku Irikyo" and the "Koga Gunchu Soso" to protect the region.
Their unity was called "Ichimi Doshin", and everything was decided by discussion.
This organizational power was also evident in the distribution of castle buildings; there were no large castles, but rather a cluster of castle buildings of the same shape.
However, with the advent of Oda Nobunaga and Toyotomi Hideyoshi, who aimed to unify the country, these self-governing organizations also underwent changes.
Nevertheless, the skills of the ninja were still valued, and in particular, the story of "Kamikun Iga Koshi", the escort of Tokugawa Ieyasu, is still told to this day.
We invite you to join us on a journey to explore the history of the ninja in depth.

A variety of lifestyles flourished in Iga and Koka

The daily life of the ninja was a combination of farming and martial arts.
The "Iran Ki" of Iga describes that they worked hard at farming in the mornings and practiced martial arts in the afternoons at a temple.
In times of war, all villagers participated in battle with their best weapons in hand.
In Iga and Koga, there were diverse occupations in addition to farming.
There was a tradition of lumberjacks and mountain priests from the Nara period (710-794), who trained their bodies in the rich natural environment and traveled around the country to gather information.
The ninja's skills were based on their daily life, knowledge, and techniques, and were by no means wild.
From knowledge of gunpowder and medicine to witchcraft and astronomy, ninjutsu was born from the advanced technology and religious culture of the Iga and Kouga, as well as the lives of their people.
We invite you to join us on a journey into the real life of the ninja.
