The soba shop on Koenji's backstreet had no QR code on the door. In 2029, this was a statement.
Yamamoto-san had been making soba on that corner for thirty-one years. She knew the government's target — everyone did, it had been in every newspaper since the national AI plan announcement, the one that said Japan would raise AI usage from 25% to 80% of individuals by fiscal 2030. The surveys said they were at 71%. Which meant there was a gap. And where there was a gap, there were officers.
Keiko arrived at 9 AM with a tablet and a Ministry of Digital Affairs lanyard.
"I'm not here to force anything," she said to the back of Yamamoto-san's head, where grey hair was tied in a knot the shape of a question mark. "I'm here to help with the onboarding process."
"I know how to make soba," Yamamoto-san said without turning around.
Keiko had been an AI adoption officer for eight months. The job existed because someone in the ministry had run the numbers and discovered that the remaining 29% was not ignorance. It was refusal. Old restaurant owners. Rice farmers in Yamagata. A composer in Kyoto who said he did not want the music to go anywhere he had not already been.
Her tablet showed a color-coded dashboard: completion rate by ward, by age bracket, by industry sector. The gaps were shaped like decisions. She spent her days visiting the shapes of those decisions and explaining to them why the shape was inconvenient.
"Do you know what it could do for you?" Keiko tried. "Inventory tracking. Recipe documentation. You could preserve your techniques — exactly as they are — for people who come after you."
"I already preserved them." Yamamoto-san tapped her temple. "In here. When I die, they go with me. That is how it is supposed to work."
Keiko looked at the old woman's hands. Flour-dusted, moving through the dough without hesitation, without checking anything, without waiting for a prompt. She had read that this kind of motor memory was essentially non-transferable — that it lived in the body and only partially in the brain, and that video documentation captured almost none of what made it what it was.
"What if someone wants to learn what you know?" Keiko asked.
"Then they come here," Yamamoto-san said, "and they watch. They come back. They watch again. That is how I learned. That is how it works."
Keiko filed her visit report on the train home. Target: non-adopter. Engaged but resistant. Recommends continuation of traditional knowledge transfer methods. Follow-up visit scheduled.
She looked at the report for a long time before she submitted it. The fields were clean, the boxes ticked, the outcome clearly coded: incomplete. She submitted it because that was her job.
That night she made instant noodles from a packet and ate them standing at her kitchen counter, thinking about flour on the backs of old hands and the exact weight of things that leave when a person does. The noodles tasted like nothing in particular. The broth was a flavor profile designed to be acceptable rather than memorable.
Somewhere in Koenji, Yamamoto-san was probably asleep. The shop would open at eleven. The dough was probably already resting in the cold.
Keiko put her bowl in the sink and added herself to the 71%.
