In 1582, Oda Nobunaga was killed by Akechi Mitsuhide who used to be a Nobunaga's general. At that time, Tokugawa Ieyasu (The first ruler in Edo goverment) had visited Sakai in Osaka. When Ieyasu heard of the death, he thought it mpossible to come back his home in Okazaki (now Aichi Prefecture), because Ieyasu was allied with Nobunaga. The only survival way was to go straight to Okazaki through Iga. But this route had a very high risk. The routes was very dangerous. Anayama Baisetsu, Nobunaga's general, was mistalen Ieyasu and was killed by the farmers in the Kizu River. It couldn't be helped to chose the way to suvive. there were many Iga Ninjas who had hated Ieyasu. In the last year, many of them were killed by Nobunaga. Ieyasu ordered his general Hattori Hanzou from Iga to hire Iga Ninjas and Koka Ninjas. Ieyasu and his group were attacked by some Iga Ninjas who didn't obey. Ieyasu could run away because of Iga and Koka Ninjas. This escape was called "Shinkun Igagoe'' and Ieyasu's most dangerous moment according to the Tokugawa Jikki which was the formal documents about the Tokugawa family. Ieyasu had a rest at Tokuei-ji in Iga. So, Tokuei-ji was permitted to use "Aoi no Mon"(the design of the Tokugawa family ) forever and got a lot of lands. (The picture is of an Onigawara, the biggest tile of roofs, with Aoi no Mon.)
