December 1987 found Tokyo in a state of complete frenzy.
With the U.S. stock market rebounding and the Bank of Japan easing monetary policy, expectations for year-end bonuses reached record heights. In Ginza, taxi drivers waved off ordinary passengers and stopped only for those holding up three fingers—signaling willingness to pay triple the fare. Department-store Christmas trees sparkled with genuine Swarovski crystals, and hotel reservations in Akasaka were already booked solid through the following year.
Amid this noisy season, The Club in Azabu-Juban preserved its distinctive tranquility.
Second floor, the core study.
"Mr. Saionji, we take your request very seriously."
Sitting across from Shuichi was Sato, managing director of the Dentsu advertising agency. This powerful figure, who controlled much of Japan's media voice, now sat upright with his hands resting on his knees in an unusually deferential posture.
Ever since Black Monday, Tokyo's upper circles had understood that the Saionji family possessed not only wealth but also the rare ability to foresee events. Receiving an order from the Saionji family was therefore more than business; it was a mark of prestige.
"Managing Director Sato."
Shuichi slid a proposal across the table.
"This Christmas, I wish to purchase the giant screen at Shinjuku Studio Alta, along with all prime-time slots on Fuji TV and the late-night programming on TBS."
Managing Director Sato opened the proposal and turned to the first page. He paused.
The page contained only a single photograph: a solitary yellow shipping container standing beside an empty, desolate stretch of abandoned railway track. Beneath the image ran a single line of small text:
"In this clamorous Christmas season, do you want to hear your true voice?"
S.A. Karaoke Box
"This…" Managing Director Sato hesitated. "Mr. Saionji, isn't this rather… somber? Everyone is seeking excitement at Christmas. I fear this 'lonely' style may not suit the festive atmosphere."
"Precisely because everyone is making noise, silence becomes all the more striking," Shuichi replied, lifting his cup of black tea. His tone remained even. "Tokyo is too loud right now. People are forced to socialize, forced to laugh, and forced to flatter their superiors at drinking parties."
He set the cup down, his gaze steady. "Trust our market research. Execute the plan exactly as written. Budget is no object; S.A. Investment will prepay the full amount."
At the mention of S.A. Investment, Managing Director Sato's pupils contracted slightly.
"Understood." He closed the proposal, rose, and bowed deeply. "Dentsu will cooperate fully. We will ensure this silent advertisement resonates across Tokyo on Christmas Eve."
At the same time, in Marunouchi at Saionji Industries headquarters, a fresh set of articles of incorporation lay on the desk.
S.A. Leisure Systems Co., Ltd.
"Stamp it, President Itakura."
Satsuki sat on the sofa by the window, reading a manga book without looking up.
Itakura wiped his sweaty palms, pressed his personal seal onto the document, and then added the company seal.
"Miss, isn't this operation spreading rather widely?" Itakura glanced at the map on the wall. In just two months, using the oddly shaped plots purchased at low cost, S.A. had already opened fifty locations across Tokyo containing a total of three hundred container boxes.
"This is only the beginning." Satsuki turned a page of her manga. "Creating this new company allows for systematic management. From now on, cleaning, maintenance, coin collection, and equipment servicing will all be handled by dedicated staff. We must run these tin boxes with the same discipline McDonald's applies to its restaurants."
She closed the book and pointed toward the stack of large cardboard boxes in the corner. "Are those the items that just arrived from Shanghai?"
"Yes!" Itakura brightened. "The 'B-grade goods' sent back by Factory Manager Takahashi—four hundred pieces in total. They are labeled seconds, but I had them inspected. Unless you examine them with a magnifying glass, the flaws are invisible."
"Very good." A faint smile touched the corner of Satsuki's mouth. "Release the announcement. Christmas Special Event: Anyone who spends a total of ten thousand yen at an S.A. Karaoke Box, or tops up a membership card with that amount, will receive an 'S-Collection Christmas Limited Edition T-shirt.' Emphasize that it is a limited edition, and use the expensive black packaging boxes with gold-stamped paper bags."
Itakura swallowed hard. "Miss, this move is ruthless. Those shirts sell for thirty thousand yen each in Shibuya boutiques, yet here we are giving them away for a ten-thousand-yen top-up plus ten hours of singing time. It is practically free."
"I believe the university students who desire that 'S' logo but cannot afford the genuine article will come in force," Satsuki said. She stood and walked to the window. "We will use these four hundred seconds to open the pockets of Tokyo's youth—and, more importantly, to open their ears. Only by drawing them into the boxes can Sachiko's voice reach their minds."
December 24, 1987. Christmas Eve.
Light snow began to fall over Tokyo. The drifting flakes turned into pink specks beneath the glow of neon signs. The city was in full revelry: streets in Roppongi were gridlocked, and couples strolled arm in arm along Omotesando to admire the illuminations.
Yet a curious scene unfolded beside the railway tracks in Shimokitazawa. Five yellow containers had been wrapped in giant red ribbons, their tops adorned with flashing LED strips and Christmas wreaths. They resembled five oversized gift boxes scattered across the snowy, desolate ground, radiating a warm glow in the dim surroundings.
In front of these gift boxes stretched a long queue of hundreds of young people, shivering yet visibly excited.
"Hurry! I heard only ten gifts remain tonight!"
"Are you serious? They are really giving away the S-Collection T-shirts?"
"Why would I lie? My roommate received one yesterday! The packaging box alone looks so prestigious when you carry it home!"
In the middle of the line, a young man removed his scarf and wrapped it around his girlfriend's neck.
"I'm sorry, Misaki. I wanted to take you to a French restaurant, but I couldn't get a reservation, and my bonus…"
"It's all right." The girl named Misaki exhaled a puff of white mist and pointed at the large yellow box. "I think this is rather nice. It will be just the two of us, without having to listen to noisy middle-aged men at the next table. And… I really want that T-shirt."
At last their turn arrived. The young man placed ten thousand yen on the counter.
"Top-up! I want the T-shirt!"
"Certainly. Here is your membership card and your gift."
The part-time worker handed over a heavy black paper bag stamped with a gold 'S'. The young man accepted it as though receiving an honor.
The couple stepped into Container No. 3. The heavy soundproof door closed with a solid thud. Instantly the outside world vanished—the cold wind, the vibration of passing trains, the chatter of the queue—all gone.
Warm air filled the box, and soft orange light bathed the leather sofa.
"It's so warm," Misaki said, removing her coat and eagerly opening the black bag. She pulled out the white T-shirt. The fabric felt smooth, and the craftsmanship was excellent. To eyes unfamiliar with the trade, it appeared identical to the exclusive item sold in Shibuya.
"This is wonderful!" She held it against herself with delight.
"Let's sing!" The young man sat at the song-selection machine and inserted a coin. "What shall we choose?"
"Tatsuro Yamashita's 'Christmas Eve,' of course! It is essential tonight!"
The introduction began. The young man prepared to sing but found the key slightly high.
"Oh, this starts a bit high…"
He noticed a red button in the lower-right corner of the screen: Guide Vocal.
"Let's try this."
He pressed it.
The next second a female voice emerged from the speakers.
"Ame wa yofuke sugi ni, yuki e to kawaru darou…" (The rain will likely turn to snow after midnight…)
That voice—clear, strong, yet filled with an indescribable tenderness—was not the original male singer's. It did not sound like a performance; it felt like a story being told directly to the listener. It cut through the electronic accompaniment and the dry air of the box, reaching straight into the hearts of the young couple.
The young man froze, forgetting to join in. Misaki stopped admiring the T-shirt and turned toward the speaker.
"Who is singing this?"
"I don't know… I have never heard this voice before."
"It's so beautiful…" Misaki whispered. "Listening to her, I feel… as though the empty place in my heart has been filled."
On this cold Christmas Eve, inside the small tin box, Sachiko's voice acted like a pair of warm hands, gently soothing the anxiety and feelings of inferiority the young lovers experienced because of their modest means and inability to afford a luxury dinner. At that moment they needed neither French cuisine nor champagne. The voice, the T-shirt, and each other were enough.
At the same moment, on the pedestrian bridge opposite Shimokitazawa Station, two figures stood by the railing, looking down at the long queue of containers.
Itakura, bundled in a thick down jacket, rubbed his hands together for warmth. Beside him stood a girl wearing a white knit hat and dark-blue scarf. Most of her face was hidden behind a mask, revealing only a pair of clear, bright eyes.
Sachiko Kamachi—soon to be known as the future ZARD.
"Do you see that?" Itakura pointed downward. "The couple who just left Box 3—they looked as though they had been crying, yet now they are smiling happily."
Sachiko watched the girl clutching the paper bag tightly, her mouth moving as though humming. Although Sachiko could not hear the sound, she could read the lip movements: the lyrics to "Christmas Eve."
"Is that my voice?" Sachiko asked softly, her words slightly muffled by the mask.
"It is yours," Itakura replied with certainty. "The young miss was right. On this frenzied night, not everyone wants to dance in a disco. Many simply wish to find a quiet place to listen to their own feelings. You have succeeded, Miss Sachiko. You are their painkiller."
Sachiko's eyes grew warm. She gripped the cold railing. Previously, as a receptionist at a real-estate office, she had felt superfluous. As a racetrack model, she had felt cheap. But tonight, seeing ordinary people find comfort in her singing, she experienced for the first time the weight of true value.
"I want to return to the recording studio," Sachiko said suddenly, her gaze resolute.
"Now? It is Christmas Eve…"
"Right now." She tightened her scarf. "There are so many more songs I wish to sing. I want to record all of them—that feeling capable of warming people."
She walked briskly down the bridge. Her back no longer appeared lost; it carried the quiet determination of an artist.
Itakura stared for a moment, then smiled with quiet satisfaction.
"Hey! Wait for me! I will drive you!"
Late that night, as the clock struck twelve, the giant screen at Shinjuku Studio Alta displayed the "Lonely Container" advertisement for the final time. Below it, thousands of young people spilled into the streets carrying paper bags marked with the gold 'S' logo.
They did not realize that every yen spent had been calculated to the last cent by the Saionji family. They only knew that this Christmas Eve had felt remarkably cool.
On that night, S.A. Karaoke Box transformed from a modest subculture experiment into a defining symbol of Tokyo's trends. And the hidden diva whose voice lived inside the boxes drifted into the dreams of countless listeners along with the falling snow, quietly awaiting the day she would emerge into the light.
