In Hirosaki City, an old folk house owned by Hideaki Aida, the chairman of the Aomori Folk Art Association, is currently being talked about at the Ninja Mansion.

The house, which was said to have been built during the Edo period, has a space (60 cm wide x 95 cm deep) where one person can hide behind the floor between the guest room and the bedroom, and a "Uguisu tension" that informs people of intrusions with a sound. There is a mechanism like this.

According to Mr. Aida, the house that Soma Teizo, the founder of the Aomori Folk Art Association, purchased in 1952 was used as a residence by Mr. Soma until 1989, but after Mr. Soma died, it was folk art. It is said to have been used at product sales events and events. Mr. Aida says, "It's 80 years old, and it's getting harder to maintain a house."

Shigeto Kiyokawa, a professor of pharmacy at the Aomori University School of Pharmacy, who conducted a survey of old houses, speculates that "Maykata Yoshikichi Munekata, the landlord two years before the house, may have been a ninja person." According to Kiyokawa, ninja as a profession seems to have declined since the Edo period, but in the Tsugaru clan, a group of ninja called "Hayamichinomono" has long existed. "Russian ships started landing in Ezo, and because of the historical background in which Hayabusa was mobilized to guard the north, ninjas remained in the Tsugaru domain," he said.

Mr. Aida said, "I was thinking about tearing it down, and it started to move around February this year. I'm glad to receive voices and advice that I want you to leave because it became a topic in the local area." The Hirosaki City Board of Education is currently conducting a survey, and plans to create floor plans and other materials within the year.

Mr. Aida says, "I have been managing it for nearly 30 years, so I would be happy if it could be taken over by the city as a cultural property, but if it can not be done, I would like someone to continue to leave it."

Mr. Kiyokawa said, "Many ninjas had a wealth of knowledge about medicine and turned to the drug business. It was possible that it was a ninja mansion even when there was a strong smell of medicinal herbs when purchased from Mr. Munakata. Expensive”.
