Chapter 16: The Nagoya Visit
The Call and the Ask, Early March 2012
The call comes on a Tuesday morning Ann Arbor time. The country code is Spain, but he doesn’t recognize the number. He answers anyway.
“Mr. Stewart, this is Fernando Casal. I hope I’m not interrupting your morning.”
The English is smooth, the cadence underneath it Spanish. No assistant puts the call through, because Casal has dialed Michael himself. Michael sets his Diet Coke on the desk beside his laptop and leans back in his chair.
“Not at all, Mr. Casal. Good to hear from you.”
Casal doesn’t waste time. He has spent a week going over Bianca’s materials and Kenji’s preliminary Nagoya briefing. What he wants now isn’t a presentation. He wants to stand beside the assembly lines where AEGIS runs live integration, watch the robotic cells cycle, and see the predictive maintenance layer catch a fault before it cascades. He wants the engineer who built the system standing next to him while it happens. That way the questions forming in his notebook get answered at the level of how the system is built, not translated through a sales layer.
“I’m not asking you to come as a bidder, Mr. Stewart. I’m asking you to come as the man who built it. There’s a difference, and I think you understand it.”
Michael says yes before the courtesy of thinking it over would require him to pause. He hears Casal’s breath shift on the other end, and the two of them settle the shape of the trip in under five minutes. Casal will bring his operations director and his chief financial officer, and Bianca will fly from Madrid. Kenji has already offered the Yamamoto residence for hospitality and the Nagoya facility for the working sessions. The dates that work on Casal’s calendar put the visit inside the following week.
“Then we’ll see each other in Tokyo,” Casal says. “Thank you, Michael.”
The line goes dead, and Michael sits looking at the whiteboard across the office, where the name Waylon Eckermann still lives in red marker beneath the word INTENT, bracketed by the node designations in blue. The week ahead is going to ask more of him than a week usually does.
He calls Kiyomi next, and she picks up on the first ring.
“Casal just phoned me directly. He wants a live site visit at Nagoya. Next week. Him, his operations director, and CFO. Bianca from Madrid. Kenji’s already offered the residence and the facility.”
When she asks about the dates he gives them to her, and she tells him she’ll call him back shortly.
She calls back inside the hour with the trip built end to end. Flights from Detroit to Tokyo Narita, a Yamamoto driver meeting them at arrivals, accommodation for Bianca and Casal’s team at The Peninsula, where non-family working guests stay. Accommodation for Michael is at the residence. Michael is considered a son of the house, and Kenji wouldn’t have it otherwise. Asuka will accompany him as his bodyguard. Rika will fly in from Kyoto to meet them at Narita and cover the rest of the party. The working sessions at the Nagoya plant are confirmed through Kenji’s operations chief, and the hospitality dinner at the residence is booked through Kenji’s household staff. Kiyomi delivers all of it without pausing for breath, then closes with one observation in the tone she uses when she wants something heard but not belabored.
“This is the signal we’ve been waiting for. The venture firms are deciding what AEGIS is worth before the Series A closes, and their money comes with strings and a piece of the company. Until now we’ve needed it. Casal calling you himself and asking for a walkthrough as your peer changes the conversation with every investor we’ve been cultivating. If Casal signs, it may change how much of that conversation we need at all. You understand what I’m telling you.”
Michael hears her and doesn’t reply.
When her voice comes back, she isn’t talking to her CEO anymore. She’s talking to the boy who stood between Mitsy and danger and has proven himself worthy ever since.
“Michael-kun.”
He closes his eyes at the sound of it. She has called him Michael since the beginning, and Michael-san in their most informal moments. She has never once used -kun. That ending belongs to a Japanese form she keeps for her actual family, the one she uses with her younger cousins and with the children of the Matsuda house. Hearing it now tells him, before she says another word, that what’s coming isn’t a business conversation.
“It’s your first time back in Tokyo.”
“I know.”
“I wanted to say it out loud before you were on the plane. Kenji won’t ask you. Asuka won’t ask you. I didn’t want you to land at Narita with no one having named it for you first.”
“Kiyomi.”
“Let me finish, Michael-kun. I’m not asking you to be ready. I’m asking you to know that I know. That’s all. Kenji knows. I spoke to him this morning before I called you back. He’s told the house staff that nothing about the arrangements will take you past Roppongi unless you ask for it. He won’t raise the subject unless you want to. Neither will I, after this call. But I’m raising it once, right now, because you’re my kōhai, and I’m not going to let you carry it into Tokyo without anyone having named it for you.”
In Kiyomi’s world a senpai takes a junior under her wing and answers for him, and that junior is her kōhai. Michael sits with the phone against his ear and doesn’t trust his voice for a moment. Outside, the March sun is working on the last of the snow along the balcony rail. Willow is one floor down in her own unit.
“Thank you,” he says.
“Are you all right with the trip.”
“I think so. I’ll know when I’m on the ground.”
“That’s an honest answer. It’s the one I expected from you.”
“Kiyomi.”
“Yes.”
“I’m glad it’s you making this call.”
“Of course it’s me. Who else would it be.”
He hears her smile through the line, the small grin that has been delighting him for four years across every difficulty he has brought to her doorstep. She doesn’t wait for him to answer.
“Go pack. Call me from the residence when you land. Don’t forget to eat on the plane.”
She hangs up first, as usual.
Michael sets the phone down on the desk, and the tightness that has been building in his chest since Casal said the word Tokyo begins to ease.
The last call is the hard one. Kyle Brennan runs a plumbing crew during the day and doesn’t like personal calls at work. Michael pulls up Kyle’s contact and dials.
“Stew. What.”
“I’m going to miss the Iceholes game. Trip to Japan, next week. Business thing I can’t move.”
Kyle swears twice, once at Michael and once at the Iceholes, and then his voice levels.
“Go do what you need to do. We’ve played without you before and we’ll play without you again. You come back from Japan with a story worth telling, I’ll consider it a net positive.”
He hangs up before Michael can thank him.
Michael stands at the whiteboard a moment longer. The name in red, the six-week Series A window Kiyomi has been pushing since January, and now a week in Tokyo that didn’t exist on his calendar at breakfast. He pulls his duffel from the closet and starts packing.
The Working Visit, Mid-March 2012
Narita in mid-afternoon. Michael walks through immigration with Asuka a half-step behind him and Bianca at his shoulder, Casal and his two colleagues moving through the adjacent queue. He hasn’t been back to Japan since December 2010. Asuka doesn’t speak, but she is closer than she needs to be, her hip nearly brushing his arm as they move through the corridor toward the concourse.
Rika meets them at arrivals in a dark suit, standing among the drivers holding placards and the families craning for faces. She and Asuka look at each other and something settles between them that Michael doesn’t try to read.
Kenji has sent two cars. One takes Casal, his CFO, and his operations director to the Peninsula. The other takes Michael, Bianca, Asuka, and Rika to the residence. Bianca will check into her hotel later; Kenji wants her at the compound for the welcome before she peels off to the Peninsula for the evening.
The Yamamoto residence receives them with everything the house has. Kenji greets Michael in the formal courtyard, embracing him as a father welcomes a son home. His hands are firm on Michael’s shoulders, and his eyes search Michael’s face until he finds what he is looking for. He nods once and releases him.
Kim has come in from Osaka ahead of them, in a simple dress rather than kimono. Her grandfather turns to her first, a hand to her shoulder and a few words in Japanese too low for the courtyard to carry. She answers him the same way before she steps back into her professional self and bows to Michael.
Kenji turns to Bianca next. They have met only over the calls that built this visit, and he greets her now in person for the first time, a slight bow and a few words of welcome in formal English, telling her the house is glad to receive the Duke’s daughter. Bianca answers with the same formality and thanks him for the honor of being received here. She and Kim have worked together in daily email for a year and are meeting in person for the first time. Bianca kisses Kim on both cheeks in the Spanish manner, and Kim takes it with her shoulders loose and her smile easy.
Welcome tea is served in a sitting room that opens onto the garden, the shoji drawn back along one wall so the koi pond lies framed beyond the veranda. Kenji speaks to Bianca about her father, the Duke’s health, and the arrangements for the week. The sun is low across the garden and the fish are slow under the surface, their orange backs catching the last angled light, and the cold sits out past the open screens. By eight Bianca has left for the Peninsula and her first night in Tokyo. Michael is in the guest quarters with his bag half-unpacked, listening to the cedar creak in the wind and not thinking about a tower he cannot see from this part of the city.
The following morning the party boards a Nozomi for Nagoya, the Tokaido Shinkansen line carrying them west through the spring countryside. A hundred minutes of farmland and low hills and the occasional pale river flickering past the window. Bianca sleeps for the first twenty of those minutes, her head tilted against the seat rest, a novel balanced on her knee. Casal reads technical materials on his tablet, working back through preparation he finished before the trip. Kim rides with them; she’ll stay in Nagoya for the working days and go back to Osaka only if an operational issue requires it. Asuka watches the platforms at each stop, her gaze tracking every entry and exit. The Nagoya facility is forty minutes from Nagoya Station by car. By late morning the party is in the Yamamoto operations conference room overlooking the main assembly floor, and Kenji’s operations chief is walking Casal through the weekly AEGIS dashboard on a wall-sized display.
The four working days settle into a rhythm Michael comes to like for its clarity. Mornings are on the plant floor in hard hats and safety gear, with the smell of metal and coolant and the faint antiseptic cleanness of a facility that is washed down at the end of every shift. Casal has spent thirty years on factory floors, and his questions go to how this line handles the failures he has seen a thousand times. He kneels beside a robotic assembly cell and runs his finger along the sensor cluster mount. He asks the operations chief how the predictive alert moves through the maintenance queue and listens to the answer with his pen resting against his lower lip. Then he writes a line in his small black notebook and moves to the next station.
Afternoons are in the conference room with the downtime data, the predictive maintenance logs, and the Busan typhoon reroute rebuilt hour by hour on the wall display. Kenji’s chief runs the commercial and operational presentation. The customer speaks to the customer, and Michael answers technical questions only when they come up. Casal’s operations director fills his own notebook in a tight script. His CFO asks financial questions that cut close to the bone and gets plain answers. Bianca watches Casal more than she watches the data, and Michael sees what she is seeing: a man who came to test a technology and is now running a different evaluation entirely. By the end of day two Casal is no longer asking whether AEGIS works. He is asking how fast he can deploy it.
Evenings are hospitality in Nagoya. A kaiseki restaurant Kenji has used for three decades. A private dining room at the hotel where the party is staying. On the Saturday night when Michael should be at the Cube, the group is in a private karaoke room in Nagoya’s Sakae district instead. Kenji’s operations chief sings Sinatra in an accent so formal it becomes its own comedy, his hands clasped behind his back as though he’s delivering a quarterly report. Casal’s CFO, reserved all week, opens his mouth and a tenor voice he has been hiding comes out and stops the room. The operations chief sets down his microphone, and Bianca leans forward in her chair. The CFO finishes, takes a small bow, and returns to his seat as though nothing has happened.
Bianca sings a Rocío Dúrcal ballad in Spanish, and when the last note fades nobody moves until Casal begins the applause. Kim sings a Japanese song Michael doesn’t know the words to and understands anyway, her voice steady and clear, her eyes closed. Michael is pushed to the microphone and delivers what he calls the worst Sweet Caroline ever sung in the Japanese islands, and Bianca laughs so hard she has to set down her drink. Asuka stands by the door all night, doesn’t sing or drink, and smiles once at something Rika says too softly for anyone else to catch. The evening ends late. In the car back to the hotel Michael checks his phone. In Ann Arbor it is still Saturday morning, the game hours away. Kyle’s text: we’ll miss you tonight. Michael reads it and puts the phone down.
The Shinkansen ride back to Tokyo on the final morning is different from the ride out. Casal sits with his operations director, and the two of them talk in low Spanish. Michael catches AEGIS, the names of two of Casal’s plants, and the word for board, and the rest goes past him. The conversation has the cadence of men who have already decided and are now building the calendar around the decision. Bianca reads the novel she has carried all week and not opened until now, her legs tucked beneath her on the seat. Kim sits across the aisle with her tablet, working through the morning’s Osaka queue. She’ll stay at the residence through the celebration dinner and return to Osaka the day after.
Michael looks out the window and watches Mount Fuji come up on the horizon north of the track, a clean white cone against a pale spring sky, and then the line bends away and it is behind them. He thinks about the reply he is still waiting for, the question he sent into the dark weeks ago, how do you know this, and what answer a man on Mars might send back. Whoever wrote that first email understood where AEGIS is going and not just how it’s built, the direction Michael has been steering toward for two years without publishing a word. He wants to know how. The countryside runs flat and gray past the glass, and Michael puts his forehead against the cool window and closes his eyes for the first good rest he has had in four days.
The final evening is the celebration dinner at the Yamamoto residence. Casal, his operations director and CFO, Bianca, Michael, Kim, the Yamamoto operations chief, and Kenji’s deputy from the Tokyo office join their host. Nine at the low table in the formal dining room, the shoji screens drawn back on the garden in early darkness, stone lanterns casting pools of amber light across the gravel path. Kenji chooses kaiseki pacing, eight courses rather than eleven, for guests with an early flight ahead of them and a long week behind them.
The conversation is easy. Kenji thanks Casal for honoring the Yamamoto facility with his visit, and Casal thanks Kenji for the week. Neither man needs the other to say what has happened commercially. The Castile bid with AEGIS is now the bid to beat, and Casal will recommend it to his board.
Mid-dinner, between the sixth and seventh courses, Michael’s phone vibrates once against his thigh. He checks it under the table. An email from Waylon, a few lines. He hopes the week went as Michael needed it to, and when Michael is back in Ann Arbor they should talk. Then the last line: and if it is not too much trouble, bring back some real nori. I’d kill for proper seaweed up here. The hair on Michael’s arms lifts, and he almost laughs in the same breath. A man forty million miles away knows he is in Japan and wants groceries. Michael’s thumb hovers over the reply field.
Casal notices the shift in Michael’s attention and asks, curious, what has captured it.
Michael looks up and smiles. “Email from a colleague about my work. He’s noticed something I hadn’t. It’ll keep.” He turns the phone face-down beside his plate. “I shouldn’t be on my phone at the table anyway.”
Kenji’s gaze stays on Michael a moment longer than the others. The conversation moves to Bianca’s favorite painters at the Prado, and the evening keeps the tone it has held since the first afternoon in the garden room.
The dinner ends when the host stands, and his guests stand with him in the same easy rhythm they kept through the meal. Coats and farewells in the formal entry. The whole party moves out through the courtyard together, Kenji and Kim at the head, Casal and his team and Bianca and Michael in loose formation behind. Kenji thanks Casal at the gate for his visit. Kim shakes the operations director’s hand, then the CFO’s, and thanks them both in English for the work they have done with her team this week. The operations director and CFO have a six o’clock flight in the morning. They take the first car and raise a hand in farewell through the window as it pulls away.
Casal stays back, and Bianca uses the pause, turning to Kim in the amber light of the lanterns. “One Yamazaki at Peter before the night ends,” she says, naming the bar at the top of the Peninsula.
Kim looks at her grandfather, and Kenji smiles and waves her on.
The residence car comes around the gravel drive. Kenji takes Casal’s hand one last time at the gate. “Give the Duke my regards,” he says.
Casal smiles. “It’ll be my honor.” The regards will be in Madrid before morning.
Kim, Michael, Bianca, and Casal are already moving through the cedar-cold air toward a nightcap. Asuka and Rika follow in a separate car to watch over the party.
The Recognition
The four of them ride through Tokyo evening traffic together, Bianca talking about Madrid weather from the far corner of the back seat, Casal laughing at something Michael has said, Michael half-turned to answer her and half-turned toward Casal. Kim sits in the forward jump seat facing them, her handbag across her knees, one leg crossed over the other, at ease in the car that has carried her and her grandfather across this city since she was a child. She likes these three, and it has been a good week. The Peninsula rises ahead as the car turns into Marunouchi, the lit windows of the upper floors arranging themselves against the darker sky, and she is already deciding she’ll order the eighteen-year Yamazaki rather than the twelve. The week has earned it.
The hostess takes them to the window table Bianca requests. Yamazaki for Bianca and Kim, the eighteen on Kim’s side of the table, ordered by name. Cardenal Mendoza for Casal, a bottle the server brings to the table for his inspection before pouring. Diet Coke for Michael, which earns a small pause from the server. The conversation moves easily, Bianca on the Prado and Casal on his daughter’s wedding next spring and Michael on Willow writing something new that she hasn’t let anyone hear yet. Kim is in good form. She teases Michael about his Diet Coke, gets Bianca laughing over a junior engineer’s remark in the Nagoya session on Tuesday, and draws Casal out on his daughter’s fiancé until he is fully delighted. She people-watches while she talks, half-curious whether she’ll spot anyone she knows.
Asuka and Rika came in a few steps behind the group and took a small table near the door, two women in good clothes out for a late drink, and from where Kim sits she can see them without looking. Rika faces the room. Asuka faces no one, and misses nothing. Kim stopped wondering years ago how much of any evening the two of them hold in their hands while the rest of the table never feels the grip.
At ten o’clock, a Japanese woman in her late twenties walks into the bar alone, in an expensive dress with an exclusive handbag, and takes a table across the room near the window. She orders a glass of wine, sets her handbag on the chair beside her, and opens the drink menu a second time without reading it. Kim’s eyes move past her and come back.
The recognition reaches her body before it reaches her mind. Kim knows the set of those shoulders, the tilt of the head over a menu nobody is reading, and the legs crossed at the ankle rather than the knee. Then the context arrives all at once. A café in Aoyama in the spring of 2009, a matcha on a small wooden table with cherry blossom on the saucer, and a laugh across the table, hearty and conspiratorial. The name the woman gave Kim across two months of cafés, lunches, and walks, a name her grandfather’s investigators later confirmed had never existed at all. A walk through Shinjuku on a June afternoon, a hand on Kim’s forearm, a taxi at night, a door, the inside of a van, and after that nothing she can clearly remember until New York.
The woman hasn’t looked at Kim. She is at her table across the room, turned slightly toward the window side of the bar, her face angled so her gaze rests on Casal and stays there. The glass of wine in front of her hasn’t been touched.
Kim sets down her whisky without letting the glass make a sound. She lets her mouth keep the smile it had a moment ago and excuses herself to the ladies’ room, lightly, as anyone excuses themselves from a table mid-evening. She takes her handbag and walks out of the bar toward the corridor.
She turns toward the small alcove by the elevators where she used to wait for her grandfather as a child when he brought her to the Peninsula for lunch. The alcove is empty. She takes out her phone and dials him. Kenji picks up on the second ring. She tells him in Japanese what she is seeing and who the woman is and where Casal is sitting. Kenji asks once whether she is certain. She says yes. He tells her he is calling Yamamoto Security now, that he’ll have people in the lobby within ten minutes and eyes on the woman through hotel security before that. He tells her she is to stay at the hotel, not confront, and not leave Bianca, Michael, and Casal at the table with that woman in the room for long. Then he asks her to put Michael on.
Kim texts Michael: Step out. She watches the mouth of the corridor. A minute later Michael comes around the corner with his phone in his hand, and he tells her as he reaches the alcove that Willow is calling, as far as Bianca and Casal know.
