Near the Hirosaki Park, a tour to explore the old houses that are said to be called "Ninja Mansion", "Together with Hirosaki Hayamichi Ninja Corps! Ninja Mansion "The Last Tour" will be held on September 22.

The same house built in the Edo period. There is a space where one person can hide behind the room between the guest room and the floor of the bedroom, and a "Uguisu tension" mechanism to inform people of invasion.

According to Shigeto Kiyokawa, a tour guide and advisor to the Ninja Club at Aomori University, “As the mansion deteriorates and maintenance costs increase, it is more likely that it will be demolished by the end of the year.”

According to Professor Kiyokawa, in the Tsugaru clan, a group of ninja called "Hayamichinomono" has survived for a long time, and there is a historical fact that it was mobilized for northern guard. "In addition to intelligence activities, he was also a chief of pharmacy, so it was said that he was witnessing the collection of medicinal herbs and the trading of medicines in the Ezo area. Traces of dried flowers and rare flowers not found in the surrounding area have also been discovered."

Professor Kiyokawa said, “For three years after the discovery, I was searching for preservation as a cultural property and utilization of inbound tourism seeking ninja, but I could not find a good idea. I hope for the last chance and before it is dismantled I want many people to know about Ninja Mansion."

Tour dates are September 22nd, October 12th and 20th. Holding time is from 13:00 to 16:30. The participation fee is 2,000 yen. Prior application is required. Accepted on the "Tsugaru Town Aruki Expo" website.
