Bunsei 12 (A.D.1829), when Mojuro Miyamoto the textile maker first visited Tokamachi he allegedly imparted Kinuchijimi weaving and new Takabata (weaving machine) to the locals.
Mojuro Miyamoto was born in Nishijin, Kyoto where the area which is advanced in textile that had once based in Jyoshu kiryu.
After his visit, the silk textile woven by this machine became major industry of Tokamachi and took its roots in the area.
　 The gimmick device based on Takabata mechanism and its technology was a high technology in those days. Each textile production regions were expecting its growth of technology and productivity, as the market was rapidly growing following economy growth. But it was still hard to understand how to program and operate the newest device.
On the other hand, there were already temple schools and dame schools spread throughout the country. And the general public acquired basic knowledge and academic skills so that they were ready to use their new skills.   Soon or later, pilgrims with most advanced knowledge and expertise would have turned up in front of them.
It was around the same time when Mojuro Miyamoto stayed in Tokamachi and when Yubun Anbori first visited this area.

　 He was from Kozukekoku Isesaki domain. Apart from he was from textile make family, there was no other detail on him. He had specialized knowledge on textile and machine, and was traveling around country.
Whereas he was a textile maker, he had developed inventions based on his own unique perspective. 
Unfortunately, these inventions were all vanished now and there is no way to confirm originals. Fragmentary data are only remained in the old book ‘Jyoshu-douguzu-irui’ ‘Echigokoku-koujinbanashi-zassan’.
It says he tried to create devices that process something that is based on binary numbers.
No one knows what these inventions are for or how he came up with these ideas. However we can presume by understanding technological situation in this area.
There once had been gimmick device called Monpi-karakuri in the area around Echigo to Jyoshu. It seems as if it behaves like a basic logic circuit, which regulates circulation of passenger, which are controlled by the door that’s open and close. For Yubun who is extremely knowledgeable in mechanism of weaving machine and also an engineer himself, he probably knew this gimmick.
Also, it was noted that he first made contact with the newly introduced weaving machine in this area. Moreover, it was presumed that he was inspired by expression of the textile pattern woven by machine, which can control whether vertical shred or horizontal shred would appear on surface.

　 After Meiji era, Japan has been rapidly modernized. Textile was the major lead industry for the growth. This could not have been achieved without highly motivated craftsman with long succession of ingenious contrivance and accumulation of technology.
　Yubun’s invention must have been one of these craftsman’s assiduous efforts.
